Best Summer-Long Flowers for Bees (Home Garden List)

By Austin Little

No single flower blooms June to September and feeds every bee. A relay of long-blooming, open-faced plants does. Here's the list, how to stack it, and what to skip.

Short answer (read this first)

If you want flowers that feed bees all summer, plant a relay, not a hero. The plants that carry a home garden through the hot months most reliably are the ones that either bloom for a long stretch on their own or keep re-blooming when you deadhead them. For most temperate US gardens, the backbone list looks like this:

• **Catmint (Nepeta)** — long flush, re-blooms after a shear.
• Lavender — strong early-to-midsummer, especially in dry, sunny spots.
• **Anise hyssop (Agastache foeniculum) and other agastaches** — mid-to-late summer workhorses.
• **Bee balm (Monarda)** — midsummer, loved by bumble bees.
• **Purple coneflower (Echinacea purpurea)** — midsummer into fall.
• **Black-eyed Susan (Rudbeckia)** — midsummer into fall.
• Single-flowered sunflowers — late summer, pollen-heavy.
• Single zinnias, cosmos, and borage — easy annuals that keep going if you keep cutting.
• Oregano, thyme, and basil left to flower — small blooms, big traffic.
• Asters and goldenrod — the late end of summer into fall, critical before frost.

Plant three or more of those in clumps, make sure something is open in every month from late spring to first frost, skip the pesticides, and you've done most of the job.

Why "all summer" is the hard part

Spring is easy. Fruit trees, dandelions, willows, and early bulbs throw a wall of bloom at bees in a short window. Fall has asters and goldenrod in many regions. The stretch that breaks a lot of gardens is mid-to-late summer, when spring bloom has finished, lawns have gone brown or been mowed flat, and heat shuts down plants that aren't adapted to it.

Beekeepers call a stretch with little nectar coming in a dearth. In many places a summer dearth shows up somewhere in July or August, though timing swings a lot with climate and rainfall.

A home garden can't fix a regional dearth by itself. It can make your block a little less of a desert, and for native bees that only forage a short distance from their nest, a little can matter a lot. That's the job: keep something useful open through the gap.

What makes a flower "good for bees" in summer

Before the list, the filter. These traits separate real forage from pretty filler:

1. Open, accessible flowers. Bees need to reach nectar and pollen. Single-petaled forms (one ring of petals around a visible center) are usually better than "double" forms bred for extra petals, which can hide or replace the pollen-bearing parts. If you can't see the center of the flower, a bee may not be able to use it.

2. Long bloom or repeat bloom. A plant that flowers for six weeks beats one that flowers for six days, especially in summer.

3. Heat and drought tolerance where you live. A plant that wilts and stops blooming in July isn't a summer plant in your yard, whatever the tag says.

4. Mass. Bees forage efficiently. A clump of one plant, roughly a yard across or more, is easier for them to find and work than a single plant tucked in a mixed border. You'll see this advice repeated in most pollinator planting guides.

5. Variety of flower shapes. Short-tongued bees (many small native bees) like shallow, open flowers: daisies, herbs, umbels. Long-tongued bees (bumble bees, some others) can work tubular flowers like bee balm and agastache. Honey bees sit somewhere in between. A mixed palette feeds more kinds of bees.

6. No systemic pesticide history. Nursery plants are sometimes treated with insecticides before sale.

The backbone list: perennials that carry summer

These come back every year once established, which means less work and deeper roots that handle dry spells better than fresh annuals. Ranges are typical, not promises.

Catmint (Nepeta)

If you plant one thing from this page, many gardeners would say catmint. It's tough, it handles poor soil and dry spells once established, and it blooms in a long first flush in late spring and early summer. The trick: when the first flush fades, shear it back by roughly a third to a half. Many varieties push a second round of bloom.

Honey bees and bumble bees both work it heavily. It's also deer- and rabbit-resistant in many gardens, which helps if you're fighting those battles.

Watch out: some catmints self-seed.

Lavender

Lavender is a summer classic for bees, especially in hot, dry, well-drained spots. It hates wet feet and heavy clay that stays soggy. English lavender (Lavandula angustifolia) types tend to bloom early-to-midsummer; lavandins (Lavandula × intermedia) often bloom a bit later and longer.

Trim after bloom to keep plants from going woody and to sometimes coax a lighter second flush. Don't cut into old bare wood; many lavenders won't regrow from it.

Agastache (anise hyssop and relatives)

Agastaches are some of the most bee-crowded plants in a summer garden. Anise hyssop (Agastache foeniculum) is native to parts of North America and blooms from midsummer into fall in many areas. Spikes of small purple flowers, licorice-scented leaves, steady visitors.

Many agastaches need good drainage and can be short-lived in wet winters. Let a few seed heads stand; they often reseed gently.

Bee balm (Monarda)

The name isn't an accident. Bee balm is a magnet for bumble bees in midsummer. Wild bergamot (Monarda fistulosa) is a widespread North American native and tends to be tougher and more open to a range of bees than some showy hybrids.

Powdery mildew is the common complaint. Give it airflow, don't crowd it, and choose mildew-resistant selections if humid summers are your norm.

Purple coneflower (Echinacea purpurea)

Coneflower is the poster plant of pollinator gardens for a reason. It blooms in midsummer and keeps going into late summer, especially if you deadhead some flowers. Bees work the raised center cone.

Skip the frilly double coneflowers with pompom centers if feeding bees is the goal. Stick with forms that show the cone. Leave some seed heads in fall; birds like them.

Black-eyed Susan (Rudbeckia)

Bright, tough, and long-blooming, rudbeckias fill the mid-to-late summer gap in many gardens. Rudbeckia hirta is often grown as a short-lived perennial or biennial; Rudbeckia fulgida is a longer-lived clumping perennial. Both draw a range of bees and other pollinators.

Salvias (perennial sages)

Many salvias bloom for a long season and re-bloom after a trim. Woodland sage types (Salvia nemorosa) handle colder climates; in warm, dry regions like much of California, native and Mediterranean sages can carry bloom deep into summer.

Not all salvias are equally useful to every bee. Some tubular, red, hummingbird-shaped salvias are built more for birds.

Mountain mint (Pycnanthemum)

Mountain mint is less famous than it should be. In much of eastern and central North America it's native, blooms in mid-to-late summer, and attracts a busy mix of small bees, wasps, and other pollinators. It spreads, but usually more politely than garden mint.

Asters and goldenrod (the late shift)

They're technically late summer into fall in most regions, but they're the last big meal before winter for many bees, so they belong in any "all summer" plan.

Annuals that fill the gaps fast

Annuals are your patch kit. They bloom the first year, they're cheap, and many keep producing as long as you keep cutting or deadheading.

Single zinnias

Zinnias bloom from early summer to frost in warm climates if you keep picking them. Choose single or semi-double forms where you can see the central disk. Fully double "dahlia-flowered" zinnias look great in a vase and often get ignored by bees. Butterflies love zinnias either way.

Cosmos

Cosmos are open, simple, and easy from seed. They often reseed. Bees and other small pollinators work the yellow centers. Plant in a sunny spot and don't over-fertilize; rich soil can give you tall leafy plants with fewer flowers.

Borage

Borage has nodding blue star flowers that bees visit constantly. It blooms for a long stretch, reseeds freely, and is easy to pull where you don't want it. It's also an edible herb, which is a nice bonus.

Sunflowers (single-headed, pollen-bearing types)

Sunflowers are a late-summer pollen bonanza, especially for native bees, some of which specialize in sunflowers. One catch: some sunflowers sold for cut flowers are bred to be pollenless so they don't drop pollen on tablecloths. Those are less useful to bees. Check the seed packet.

Phacelia

Lacy phacelia (Phacelia tanacetifolia) is famous among bee people and often used in cover crop mixes. It blooms relatively quickly from seed and can be sown in succession for more weeks of bloom. In hot summers it may finish quickly, so succession sowing helps.

Basil, cilantro, dill, and other herbs allowed to bolt

This is the easiest trick in the book. Let a few herb plants go to flower instead of pinching every bud. Flowering basil draws bees hard. Dill and cilantro (coriander) give you umbrella-shaped flower heads that small native bees and beneficial wasps like. Leave a few, harvest the rest.

Shrubs and bigger plants that anchor summer bloom

If you have space, a few woody plants give you a lot of bloom per square foot.

• **Blue mist shrub (Caryopteris)** — late summer blue flowers, very busy with bees.
• **Bluebeard / chaste tree (Vitex)** — in warm climates, long summer bloom.
• Abelia — long-blooming small flowers in many warm regions.
• Native shrubs in your region — for example, in parts of California, buckwheats (Eriogonum) carry bloom through dry summer months.

**A word on butterfly bush (Buddleja).** It's popular and does draw insects, but it's listed as invasive in some states and regions. If you grow it, choose sterile cultivars and check your local invasive plant list first.

Building the relay: a month-by-month way to think about it

Here's a simple structure that works in a lot of temperate gardens. Shift it a month earlier for warmer, longer summers and a few weeks later for short northern summers.

Late spring to early summer

• Catmint (first flush)
• Lavender (English types)
• Salvia nemorosa
• Borage and phacelia from early sowings

Midsummer

• Bee balm
• Coneflower
• Agastache starting
• Zinnias and cosmos in full swing
• Flowering basil and oregano
• Lavandins

Late summer

• Agastache and mountain mint at peak
• Rudbeckia
• Sunflowers
• Catmint second flush (if sheared)
• Caryopteris

End of summer into fall

• Asters
• Goldenrod
• Late zinnias and cosmos
• Sedum (stonecrop) types in many gardens

If you walk your garden on the first of every month from May to October and can point to at least three things blooming, your relay is working. If one month is empty, that's the gap to fill next season.

Native plants vs garden favorites

You don't have to pick a side. A lot of gardens do best with a mix:

• Native plants support native bees that evolved with them, including some specialist bees that only collect pollen from specific plant groups. They're usually adapted to your rain, soil, and heat.
• Non-invasive garden plants like catmint, lavender, and many herbs feed generalist bees, including honey bees, and are easy to find at any nursery.

If you want to lean native, regional plant lists from organizations like the Xerces Society, your state's native plant society, or your local cooperative extension office are the best starting place.

Simple habits that stretch bloom by weeks

The plant list matters. What you do with the plants matters almost as much.

Deadhead. Removing spent flowers before they set seed tells many plants to make more flowers. This works on zinnias, cosmos, coneflowers, salvias, and lots more. Toward the end of the season, stop deadheading some plants and let them seed for birds and next year.

Shear and reset. Catmint, some salvias, and similar plants respond to a hard trim after their first flush with a second bloom.

Succession sow. Sow a short row of annuals like cosmos, zinnias, phacelia, or borage every few weeks from spring into early summer. Each batch peaks at a different time.

Water deeply, not daily. Plants stressed by drought often stop flowering. In dry summers, a deep soak at the root zone once or twice a week (adjusted to your soil and local water rules) usually beats a nightly sprinkle. Drip or soaker lines also keep water off the flowers.

Don't over-feed. Heavy nitrogen fertilizer often grows leaves at the expense of flowers. Most of the plants on this list prefer lean-to-average soil.

Plant in clumps. Three to five of the same plant grouped together beats one of each scattered around.

What to skip or think twice about

• Double-flowered forms. Frilly, petal-packed flowers often hide pollen and nectar. Pick singles.
• Pollenless cut-flower sunflowers. Great in a vase, less useful to bees.
• Invasive species. Check your state's invasive plant list. A plant that feeds bees but escapes into wild areas can crowd out native forage.
• Plants pretreated with systemic insecticides. Ask your nursery.
• "Bee-friendly" seed mixes with no species list. If the bag doesn't tell you exactly what's in it, you can't check it for invasives or for fit with your region.
• Spraying anything on open flowers. If you must treat a pest problem, read the label, follow it exactly, and never spray blooming plants when bees are active.

Small-space version: balcony, patio, or one bed

You don't need an acre. A short list for containers and small beds:

• One large pot of catmint or lavender (sunny spot, good drainage).
• One pot of basil and oregano you let flower.
• A pot or window box of single zinnias or cosmos (dwarf varieties exist).
• A pot of agastache if you get strong sun.
• A late-season pot of asters or a compact sedum.

Water containers more often than beds; they dry quickly in summer heat. Group pots together so bees see one bigger patch rather than scattered single plants.

Don't forget water and nesting

Flowers are only half of a bee garden.

Water. Bees drink, and honey bees haul water back to cool the hive in heat. A shallow dish with stones or marbles sticking above the water gives them a landing spot so they don't drown. Change it every few days so it doesn't breed mosquitoes.

Nesting. Many native bees nest in bare, undisturbed soil. Others nest in hollow stems or old beetle tunnels in wood. Leave a sunny patch of bare ground unmulched, and leave some cut flower stalks standing through winter (cut to varied heights in spring) so stem-nesting bees have homes.

A garden full of summer flowers and no nesting habitat feeds visiting bees but doesn't help them raise the next generation nearby.

Honey bees vs native bees in your summer garden

You'll likely see both. Honey bees are managed livestock that may be flying in from a hive somewhere in the neighborhood. Native bees include bumble bees, sweat bees, mining bees, leafcutters, carpenter bees, and many others, often smaller and easy to miss.

A diverse flower palette helps both. Some research has raised concerns that dense honey bee populations can compete with wild bees for limited forage in some settings. That's not a reason to panic about a neighbor's hive.

Safety notes for a bee-busy garden

Planting for bees means more bees near paths, patios, and play areas. Most foraging bees are focused on flowers and aren't aggressive away from their nests. Still:

• Put the busiest plants a few steps back from doorways and seating if anyone in the household is nervous or allergic.
• Teach kids not to grab or swat at bees on flowers.
• Wear shoes on lawns and flower-dense paths; stepping on a bee is a common way to get stung.
• If anyone in the household has a known bee or wasp venom allergy, talk to their doctor about precautions before turning the yard into a bee magnet.

A simple starter plan you can copy

If you want a decision instead of a list, here's a sunny-bed plan for a typical temperate yard:

1. Back row: coneflower, rudbeckia, and a clump of sunflowers.
2. Middle row: bee balm, agastache, and mountain mint (or a native alternative for your region).
3. Front edge: catmint and lavender.
4. Gaps and edges: zinnias, cosmos, and borage from seed.
5. Herb corner: basil, oregano, and thyme left to flower.
6. End-of-season anchors: a native aster and a goldenrod suited to your area.

Plant in clumps, water through the first summer while roots establish, deadhead through August, and leave seed heads standing in fall.

How to tell if it's working

You don't need a lab. You need a lawn chair and ten minutes.

• Pick a sunny, calm morning once a week.
• Sit near the bed and count how many different kinds of bees you notice. Big fuzzy ones, tiny shiny ones, striped honey bees.
• Note which plants have the most traffic.
• Write it down with the date.

After one season you'll know which plants are earning their space in your garden, which ones bees ignore, and which month needs help. That's better data for your yard than any national list, including this one.

Common mistakes

Planting one of everything. A scattered "pollinator garden" with one plant per species looks nice and feeds fewer bees. Clump.

All spring, nothing after June. The most common gap. Walk the garden in late July. If it's quiet, add agastache, rudbeckia, sunflowers, asters, or mountain mint.

Deadheading too tidy in fall. Seed heads feed birds, and stems house bees. Let some stand.

Mulching every inch. Thick mulch over every bed blocks ground-nesting bees. Leave some bare, sunny soil.

Spraying "just a little." Any insecticide on blooming plants is a risk to bees. If there's a problem, identify the pest first, try non-chemical fixes, and follow labels to the letter if you treat.

FAQ

What is the single longest-blooming flower for bees? There isn't one that wins everywhere. Catmint, many salvias, agastache, and zinnias with regular deadheading are common long-season picks in temperate gardens. Your climate decides the winner.

Do bees like marigolds? Some single marigolds get bee visits; heavily doubled forms usually get far fewer. If bees are the goal, other annuals on this list are stronger choices.

Are hydrangeas good for bees? Mophead hydrangeas are mostly sterile showy florets and offer little.

How many plants do I need? Start with three to five plants of each of at least three species, staggered across the season. Grow from there.

Will a bee garden bring wasps? You'll see some wasps; many are beneficial predators and pollinators. Yellow jackets are a separate issue tied mostly to protein and sugar sources, not flowers. See Apiary's yellow jacket guides for that.

The bottom line

The best summer-long flower for bees is a sequence: catmint and lavender early, bee balm and coneflower in the middle, agastache, rudbeckia, and sunflowers late, asters and goldenrod at the end, with zinnias, cosmos, borage, and flowering herbs filling the cracks. Plant in clumps, choose single flowers, deadhead to stretch bloom, leave some bare ground and stems for nesting, and keep pesticides off open flowers.

Walk the garden every month from late spring to frost. If something's blooming each time, the bees will find it.
