Bee friendly plants: the best flowers, trees and shrubs for bees in every US region

Bee friendly plants are the ones that give plenty of nectar and pollen in flowers bees can actually open, and the best garden is one where something is in bloom from the first warm day of late winter to the last frost of fall. Across most of the US that means willows, red maple and fruit trees in spring; native mints, coneflowers, sunflowers and clovers in summer; and goldenrods and asters in fall, with single rather than double flowers. Because the country spans deserts, rain forests and subtropical swamps, the right species depend on where you live: this guide gives a calendar, region-by-region picks from the Northeast to California, how to turn a lawn into a bee lawn, which plants your state may ban, and what all this means for the honey in a beekeeper’s jar.

What makes a plant good for bees?

Bees collect two things from flowers. Nectar is a sugar solution that fuels flight and, in the honey bee, becomes honey. Pollen supplies the protein, fats, vitamins and minerals every larva is raised on. A plant can be rich in one and poor in the other: red maple is valued mostly for early pollen, basswood for its July nectar. A good planting covers both.

Four things decide whether a plant pulls its weight:

• Reward: how much nectar and pollen each flower makes and how many flowers the plant carries. One mature linden or tulip poplar holds more food than a whole bed of annuals.
• Access: whether a bee can reach it. Deep tubular flowers suit long-tongued bumble bees and hummingbirds; open, shallow flowers suit honey bees, sweat bees and small native bees.
• Timing: food in March or September is worth more than food in late May, when almost everything blooms at once.
• Mass: bees work patches. Plant at least 3 ft by 3 ft (1 m by 1 m) of one species, or three to five plants together, rather than scattering single plants.

Single flowers, not doubles

Many ornamentals have been bred for double flowers, where extra petals replace the stamens that carry pollen and crowd the nectar out of reach. Double petunias, double begonias, pompom dahlias and most bedding geraniums are poor bee plants. Choose single, open forms with a visible center: single dahlias, single roses, species zinnias and cosmos.

Native plants and honey bees

The US has thousands of native bee species, and many of them are tied to native plants. The best evidence for this comes from a three-year Oregon State University study, published in 2022, which grew Willamette Valley wildflowers at the North Willamette Research and Extension Center from 2017 to 2019 and collected 57 bee species on them. Its top 10 native picks were varileaf phacelia, globe gilia, Douglas’ aster, California poppy, farewell-to-spring, rose checkermallow, common madia, Canada goldenrod, Oregon sunshine and common yarrow. Douglas’ aster attracted the widest variety of bees, and lavender, one of the non-native comparison plants, attracted the fewest bee species.

The honey bee is itself an introduced, generalist species, and much of the US honey crop comes from non-native plants such as white and sweet clover, alfalfa and citrus. For a yard planting, the practical rule is to build the backbone from regional natives and add proven non-natives, such as culinary herbs, where they fill a gap.

Which bee friendly plants bloom when?

The table gives a general sequence for the eastern half of the country. Move everything about six to eight weeks earlier in the Gulf states and Florida, and two to four weeks later in northern New England and the Upper Midwest. For what colonies are doing at each point, see our beekeeping calendar.

Season	Trees and shrubs	Perennials and herbs	Wild and farm plants	Main reward
Late winter (Feb to Mar)	Red maple, silver maple, willows, witch hazel, elm	Crocus, snowdrop, hellebore	Henbit, purple dead nettle, chickweed	Pollen
Early spring (Mar to Apr)	Redbud, serviceberry, wild plum, cherry, pear, apple, blueberry	Creeping phlox, rosemary in the South	Dandelion, mustards, early clovers	Pollen and nectar
Late spring (May to Jun)	Black locust, tulip poplar, hawthorn, holly, blackberry	Penstemon, salvia, catmint, chives, baptisia	White clover, vetch, alfalfa	Main flow in much of the East
Summer (Jul to Aug)	Basswood (American linden), sumac, sourwood in the Appalachians, chaste tree	Bee balm, anise hyssop, mountain mint, purple coneflower, blazing star, oregano, thyme, borage, sunflowers	Sweet clover, alfalfa, milkweed, soybeans and cotton in some areas	Nectar; summer dearth in the Southeast and much of the West
Fall (Sep to Oct)	Seven-son flower, abelia	Asters, goldenrods, sedum, boneset, Joe Pye weed	Goldenrod, aster, Brazilian pepper in central and south Florida	Fall flow and winter pollen

Late winter and spring

The first big pollen in the eastern US usually comes from red maple. The North Carolina Department of Agriculture’s apiary calendar for central North Carolina has red maple pollen starting brood rearing in February. In the North the same trees bloom in March or April, often alongside willows. Dandelions follow in every lawn; leave them to flower rather than spraying them, because in many places they are the main food between the trees and the fruit bloom.

The summer dearth

In much of the country there is a lull after the spring flow. In central North Carolina the apiary calendar warns that nectar is scarce in August, when bees turn defensive and rob; in Florida the UF/IFAS management calendar has the main flow stopping in July everywhere. Gardens can make up some of the gap with plants that bloom through heat: mountain mint, anise hyssop, bee balm, oregano, purple coneflower, sunflowers, blazing star and, in the South, chaste tree and crape myrtle (which gives pollen but little nectar).

Fall: goldenrod and aster

Goldenrods and asters are the backbone of fall forage from the Atlantic to the Rockies. They feed honey bees building winter stores, bumble bee queens fattening before hibernation and many late native bees. If you have one patch of “weeds” to leave alone, make it these. Goldenrod does not cause hay fever; ragweed, which blooms at the same time and is wind-pollinated, does.

What should you plant in your region?

There is no single national list. Two free resources narrow the choice to your area. The Xerces Society publishes “Native Plants for Pollinators and Beneficial Insects” lists for the Northeast, Mid-Atlantic, Southeast, Florida, Great Lakes, Midwest, Northern and Southern Plains, Rocky Mountains, Great Basin, Inland Northwest, Maritime Northwest and four Southwest regions, with separate “Recommended Plants” lists for California. Pollinator Partnership offers 36 US ecoregional planting guides, free as PDFs, which you find by entering your zip code; they were funded by partners including the National Fish and Wildlife Foundation, the U.S. Forest Service and the Bureau of Land Management. Your land-grant university extension service and state native plant society can confirm what grows well in your county.

Northeast and Mid-Atlantic

• Spring: red maple, willows, serviceberry, redbud, highbush blueberry, fruit trees.
• Early summer: black locust, tulip poplar (south of New England), white clover, catmint, penstemon.
• Summer: basswood, sumac, bee balm, mountain mint, anise hyssop, swamp milkweed, purple coneflower, oregano.
• Fall: New England aster, smooth aster, goldenrods, Joe Pye weed, boneset.

Midwest and Great Plains

• Spring: willows, maples, wild plum, crabapple, dandelion.
• Summer: white and sweet clover, alfalfa, basswood, wild bergamot (Monarda fistulosa), purple prairie clover, leadplant, prairie blazing star, rattlesnake master, sunflowers.
• Fall: stiff goldenrod, showy goldenrod, aromatic aster, sky blue aster.

The northern Plains are the honey belt of the country, built largely on clover and alfalfa: USDA’s March 2026 honey report put North Dakota first in 2025 with 30.8 million lb (about 14,000 metric tons) of a national 116 million lb (about 53,000 metric tons).

Southeast

• Late winter: red maple, henbit, wild plum.
• Spring: tulip poplar, black locust, blackberry, holly, gallberry on the coastal plain.
• Summer: sourwood in the southern Appalachians, sumac, clover, mountain mint, partridge pea, butterfly milkweed.
• Fall: goldenrods, asters, frostweed, and in the mountains late aster flows.

The central North Carolina apiary calendar puts the heaviest flow in April and the scarcest nectar in August. NC State Extension describes sourwood honey as usually amber, with a buttery, caramel-like flavor.

Florida and the Gulf Coast

Florida has almost no true dormancy. The UF/IFAS calendar has the primary flow starting in April in north Florida and orange blossom honey extracted from late April in south Florida, with a fall flow from Brazilian pepper in central and south Florida in September. In the Panhandle, the Gulf County extension office describes tupelo bloom from about mid-April to the end of May along the Apalachicola River and the Dead Lakes. Saw palmetto and gallberry give other regional honeys. For gardens, choose native plants that handle heat and sandy soils: dotted horsemint, beach sunflower, blanket flower, coreopsis (the state wildflower), firebush for long-tongued visitors and saw palmetto for larger yards. Brazilian pepper is a major bee plant but a listed invasive in Florida: never plant it.

Pacific Northwest

West of the Cascades, the Oregon State list above is the best starting point: varileaf phacelia, globe gilia, Douglas’ aster, California poppy, farewell-to-spring, rose checkermallow, Oregon sunshine, Canada goldenrod and yarrow. Bigleaf maple, willows, Oregon grape, red-flowering currant and snowberry are useful native shrubs and trees. Himalayan blackberry gives honey bees a major summer flow but is invasive; do not plant it.

California

California’s beekeeping year starts with almonds, which bloom in February. The California Department of Food and Agriculture’s border inspection report for the 2025/26 season counted 4,619 truckloads of bees, an estimated 1.9 million colonies, entering the state for pollination between September 2025 and mid-March 2026. Beyond the orchards, native sages (black, white and purple sage), California buckwheat, ceanothus, manzanita, California poppy and phacelias are excellent bee plants that also survive summer drought. Yellow starthistle shows the trade-off between forage and weeds: UC IPM calls it an important source of pollen and nectar for honey production, but estimates that it infests over 14 million acres in California, and it is toxic to horses.

Southwest and Intermountain West

In dry country, choose natives adapted to little water: desert willow, mesquite and catclaw acacia in the low deserts; Rocky Mountain bee plant, globemallow, penstemons, rabbitbrush, desert marigold and sunflowers at higher elevations. Irrigated alfalfa and sweet clover carry much of the honey crop in Utah, Idaho and neighboring states.

Which trees and shrubs feed the most bees?

A single large tree can give more flowers per square foot of ground than any flower bed, and it keeps giving for decades.

Tree or shrub	Region	Bloom	Value for bees
Red maple (Acer rubrum)	East	Feb to Apr	Early pollen and some nectar
Willows (Salix spp.)	Nationwide	Feb to Apr	Pollen (male plants) and nectar; native species in every region
Serviceberry (Amelanchier)	East and Midwest	Mar to Apr	Nectar and pollen; small yard tree
Eastern redbud	East and South	Mar to Apr	Nectar for early bees
Fruit trees (apple, pear, cherry, plum)	Nationwide	Mar to May	Nectar and pollen; need bees to set fruit
Black locust	East and Midwest	May	Heavy nectar in a good year
Tulip poplar (Liriodendron tulipifera)	East and South	Apr to Jun	Major nectar tree; dark honey
Basswood or American linden (Tilia americana)	East and Midwest	Jun to Jul	Major nectar flow; pale, minty honey
Sourwood (Oxydendrum arboreum)	Southern Appalachians	Jun to Aug	Prized varietal honey
Ogeechee tupelo (Nyssa ogeche)	Florida Panhandle and south Georgia river swamps	Mid-Apr to May	Tupelo honey
Citrus	Florida, California, Texas	Mar to Apr	Orange blossom honey
Sumac (Rhus spp.)	Nationwide	Jun to Jul	Summer nectar and pollen

Sourwood makes a good small ornamental tree in acid soils, with white summer flowers and fall color from peach to scarlet and reddish purple, but do not expect a crop: NC State Extension notes that sourwood blooms from June to August, and that honey enthusiasts claim an excellent sourwood crop comes only about once a decade, depending on weather, timing and beekeeping skill.

Which garden flowers and herbs are best for bees?

The plants below are reliable across most of the country and easy to find. Check that each one is suited to your soil and hardiness zone.

• Mint family: bee balm, wild bergamot, anise hyssop, mountain mint, oregano, thyme, catmint, salvia, rosemary, lavender (more for bumble bees and honey bees than for native specialists).
• Daisy family: purple coneflower, black-eyed Susan, sunflowers, coreopsis, blanket flower, asters, goldenrods, single zinnias and cosmos.
• Others: blazing star (Liatris), milkweeds, penstemon, borage, phacelia, baptisia, purple prairie clover, sedum.

Containers, patios and balconies

A sunny balcony can feed bees if it has some bloom from spring to fall. Use pots at least 8 to 12 in (20 to 30 cm) deep, and group three or four of the same plant together.

Container plant	Pot depth	Bloom	Notes
Crocus and grape hyacinth	6 in (15 cm)	Feb to Apr	Plant bulbs in fall
Chives and thyme	6 to 8 in (15 to 20 cm)	May to Jul	Let them flower
Oregano	8 in (20 cm)	Jul to Sep	One of the best bee herbs
Anise hyssop	12 in (30 cm)	Jul to Sep	Native to the northern Plains and Midwest
Purple coneflower	12 in (30 cm)	Jun to Aug	Leave seed heads for birds
Salvia (native species for your region)	12 in (30 cm)	Jun to frost	Good in the South and West
Aromatic aster	12 in (30 cm)	Sep to Oct	Compact native fall aster

Water deeply in heat waves: drought-stressed plants produce less nectar.

Vegetable gardens

Squash, pumpkins, cucumbers, melons, tomatoes (buzz-pollinated by bumble bees), beans, blueberries, raspberries and strawberries all feed bees and give better crops when bees visit. Squash bees, native to the Americas, often reach squash and pumpkin flowers at dawn before honey bees are flying. Let a few herbs, such as cilantro, dill, basil and oregano, bolt and flower.

How do you turn a lawn into a bee lawn?

A bee lawn keeps the turf but lets low flowers bloom in it. The University of Minnesota tested the idea in Minneapolis parks with funding from the state’s Environment and Natural Resources Trust Fund. The project used low-input fine fescues and seeded Dutch white clover, self-heal and creeping thyme into them. Surveys from 2016 to 2018 recorded 62 bee species on flowering lawns across 280 site visits; Dutch white clover alone hosted 55 wild bee species, and seven species were found only on self-heal. Lawns with all three flowers had more diverse bee communities than lawns with clover only.

How to do it:

1. Prepare the turf. Late summer or early fall suits cool-season lawns in the North. The Minnesota team mowed the existing lawn very short, under 1 in (2.5 cm), and aerated it before overseeding.
2. Overseed with a mix of fine fescues and low flowers suited to your region: white clover, self-heal and creeping thyme in the North; in the South, consider native options suggested by your extension office.
3. Mow higher and less often. Self-heal kept flowering in the study even with regular mowing to 3.5 in (9 cm). Every two to three weeks in summer lets clover rebloom between cuts.
4. Stop broadleaf herbicides, which kill clover and every other flower in the turf.

Minnesota’s Board of Water and Soil Resources runs Lawns to Legumes, which reimburses residents up to $400 of the cost of establishing pollinator habitat in their yards during sign-up periods; as of October 2026 its individual grant program was not open for applications. Some cities and watershed districts elsewhere offer similar rebates, so ask your local soil and water conservation district.

Which plants should you avoid?

State noxious weed lists

Several good bee plants are invasive in parts of the US, and the rules are set state by state, sometimes county by county. A few examples:

• Butterfly bush (Buddleja davidii): in Oregon, the noxious weed quarantine allows only Oregon Department of Agriculture approved seedless cultivars, which produce 2% or less viable seed, such as ‘Blue Chip’, ‘Ice Chip’ and ‘Purple Haze’, and certain interspecific hybrids such as ‘Miss Molly’ and ‘Miss Ruby’, to be propagated, moved or sold. In Washington, King County’s noxious weed program lists it as a non-regulated Class B noxious weed and says the state quarantine makes it illegal to buy, sell or offer the species for sale. In most other states it is legal, and it is far better for butterflies than for bees.
• Yellow starthistle: a valued honey plant in California but a damaging weed of rangeland that is toxic to horses.
• Himalayan blackberry, Brazilian pepper and purple loosestrife are all productive bee plants and all invasive where they have escaped. Do not plant them, and follow your state’s control rules.

Before buying anything unfamiliar, check your state department of agriculture’s noxious weed list and your state invasive plant council.

Plants treated with systemic insecticides

Some nursery stock and bedding plants are grown with systemic insecticides that move into nectar and pollen. Minnesota addressed this in its pollinator labeling law, Minnesota Statutes 18H.14, first passed in 2014 and last amended in 2023: a seller may not label or advertise annuals, bedding plants or nursery stock as beneficial to pollinators if they were treated with a systemic insecticide whose label carries a pollinator or bee precautionary statement and they have a concentration in their flowers or leaves above the “reference value”. The state agriculture commissioner sets that value, based on pollinator protective values published or approved by EPA. Few states have such a rule, so ask the nursery how plants were grown, buy from growers who do not use systemic insecticides, or start bee plants from seed.

How can farms and larger properties add habitat?

On farmland, pollinator strips and blocks can be enrolled in federal conservation programs. The USDA Farm Service Agency’s practice CP42 (pollinator habitat) under the Conservation Reserve Program requires each habitat area to be at least 0.5 acre (0.2 ha), with strips at least 20 ft (6 m) wide; contracts run 10 years with annual rental payments. FSA’s May 2025 continuous CRP fact sheet lists cost-share of up to 50% of eligible establishment costs, a practice incentive of up to 50%, and a signup incentive of 32.5% of the first full year’s rent. That fact sheet noted CRP authority ran only to September 30, 2025 under a short-term extension: authority and sign-up periods depend on Congress and the Farm Bill, so check with your FSA county office and your Natural Resources Conservation Service (NRCS) office, which also funds pollinator plantings through other conservation programs.

For any planting larger than a garden bed:

1. Control weeds for a full season first, by repeated tillage, smothering or herbicide, because perennial weeds are the main reason pollinator plantings fail.
2. Choose a regional seed mix of at least a dozen native wildflowers that cover spring, summer and fall, using the Xerces or Pollinator Partnership lists, plus a few native bunchgrasses.
3. Sow in late fall or winter in the North, where freezing and thawing help many native seeds germinate, or at the start of the rainy season in California and the Southwest.
4. Mow high in the first year to keep annual weeds from shading seedlings, then mow or burn only part of the planting each year so some habitat is always left for overwintering insects.

What do bee plants mean for beekeepers?

Forage range

Honey bees fly well beyond the yard. A study that decoded 5,097 waggle dances over two years found mean foraging distances of about 540 yards (493 m) in spring, 1.3 miles (2,156 m) in summer and 0.8 mile (1,275 m) in fall. Bees fly farthest when flowers are scarcest. The forage within a couple of miles of your apiary, not just your garden, decides how much honey you take, which is why siting comes first in where to put a beehive. Many native bees forage only a few hundred yards from their nests; see our guide to wild bees.

US honey plants and their honeys

Plant	Main regions	Flow	Honey
White and sweet clover	Northern Plains, Midwest, Northeast	Jun to Aug	Pale, mild; the classic table honey
Alfalfa	Plains, Intermountain West	Jun to Aug	Pale, mild, granulates fairly fast
Orange blossom (citrus)	Florida, California, Texas	Mar to Apr	Light, floral
Tupelo	Florida Panhandle, south Georgia	Apr to May	Light, buttery, very slow to granulate
Tulip poplar	East and South	Apr to Jun	Dark amber
Sourwood	Southern Appalachians	Jun to Aug	Usually amber, buttery and caramel-like; much sought after
Basswood	East and Midwest	Jun to Jul	Pale, minty
Buckwheat	Northeast and Midwest where grown	Jul to Sep	Very dark, malty, strong
Sage	Southern California	Spring	Pale, slow to granulate
Goldenrod and aster	Northeast, Midwest, South	Aug to Oct	Golden, strong aroma; often left for the bees

Beekeepers who want a varietal honey take off or extract supers just before the target bloom. The central North Carolina apiary calendar, for example, suggests harvesting before the sourwood flow begins in mid-June so the sourwood crop stays pure.

Labeling a floral source

FDA’s February 2018 guidance on the proper labeling of honey says that naming a floral source such as “clover honey” or “orange blossom honey” is optional, but if you do it you should be able to support that the named plant is the chief floral source. Some states have their own honey standards on top of this. Our guides to harvesting honey and how to choose honey cover extraction, labeling and what the names on the jar mean.

When forage runs short

Planting helps, but no yard can carry a colony through a drought, a cold spring or a summer dearth on its own. Heft or weigh your hives before winter and after the main flow, and if they are light see our guide to feeding bees.

Frequently asked questions

What are the best bee friendly plants for a US garden?

It depends on your region, but a few groups work almost everywhere: native asters and goldenrods for fall, mints such as bee balm, mountain mint and anise hyssop for summer, and willows, red maple and fruit trees for spring. In Oregon State University trials, Douglas' aster attracted the widest variety of bees. Use the free Xerces Society or Pollinator Partnership lists for your ecoregion.

Are native plants better for bees than garden flowers?

For wild bees, usually yes. In a three-year Oregon State University study in the Willamette Valley, native wildflowers such as varileaf phacelia and Douglas' aster drew far more bee species than non-native comparison plants, and lavender attracted the fewest. Honey bees are generalists and also work many non-native plants, such as clover, alfalfa and citrus, but a native-based garden feeds both.

Is butterfly bush bad for bees?

It is a weak bee plant and an invasive one in the Pacific Northwest. Oregon allows only approved seedless cultivars or certain hybrids to be sold, under its noxious weed quarantine, and King County says Washington's quarantine makes it illegal to buy or sell the species in the state. Elsewhere it is legal, but native alternatives like mountain mint or New England aster feed more bees.

What is a bee lawn?

A bee lawn is turf in which low flowering plants grow among the grass. University of Minnesota research in Minneapolis parks used fine fescues with Dutch white clover, self-heal and creeping thyme, and found 55 wild bee species on clover alone, while seven species appeared only on self-heal. Minnesota's Lawns to Legumes program has reimbursed residents up to $400 for such plantings.

What flowers bloom first for bees in spring?

In most of the eastern US, red maple and willows give the first big pollen of the year, from February in the South to April in the North, followed by dandelion, henbit, redbud, serviceberry and fruit trees. In California, almond bloom in February is the first major source for millions of colonies. Crocus and other early bulbs add a little pollen in gardens on warm days.

Can I plant to make tupelo or sourwood honey?

Not really. Both come from native trees that grow in specific places. Tupelo honey comes from Ogeechee tupelo (Nyssa ogeche) in the river swamps of the Florida Panhandle and south Georgia, and sourwood from the southern Appalachians, where, as NC State Extension reports, honey enthusiasts say an excellent crop comes only about once a decade. You can plant a sourwood tree as an ornamental, but a varietal honey needs whole forests in bloom.

Do pesticides on nursery plants harm bees?

They can. Some bedding plants and nursery stock are treated with systemic insecticides that move into nectar and pollen. Minnesota law bars retailers from labeling or advertising such plants as beneficial to pollinators if their flowers or leaves carry residues above a reference value set by the state using EPA data. Elsewhere, ask the nursery how plants were grown or raise bee plants from seed.

How far will honey bees fly to reach my flowers?

Usually within a mile or two. In a study that decoded more than 5,000 waggle dances, honey bees foraged on average about 540 yards (490 m) from the hive in spring and about 1.3 miles (2.2 km) in summer, when flowers were scarcer. Many native bees forage much closer to their nests, so a yard planting mostly feeds bees from the neighborhood.
