Plants That Attract Bees in Colorado

What Bees Actually Need From a Garden

Attracting bees isn't about any single plant — it's about continuous bloom. Colorado's native bees and honeybees need nectar from the last frost to the first one, and most yards have a bloom gap in late summer when everything planted in a spring garden-center run has finished. The plants below are chosen so their bloom windows overlap into an unbroken season.

Two more things matter more than people expect: plant in drifts (a three-by-three-foot patch of one species is far easier for bees to find and work than singles scattered around the yard), and skip the systemic insecticides — a treated plant feeds poison to exactly the visitors you invited.

The Six Workhorses

English Lavender shrub

English Lavender

Lavandula angustifolia

Height
18–24 inches
Width
18–24 inches
Sun
Full sun
Water
Low
Bloom
Late spring into summer

Lavender is a honeybee magnet and thrives in exactly the conditions Colorado provides free of charge: sun, lean soil, and dry air. Sharp drainage is the one requirement it won't negotiate — plant it high, never in a low wet spot.

Shear it lightly after the first flush and most years it gives a second, smaller bloom.

Rocky Mountain Penstemon shrub

Rocky Mountain Penstemon

Penstemon strictus

Height
24–30 inches
Width
18–24 inches
Sun
Full sun to light shade
Water
Very low
Bloom
Late spring to midsummer

A true Colorado native with electric blue-purple spikes that bumblebees work all day, and one of the best plants in the state for native bee species. Once established it wants essentially no supplemental water in a normal year.

Let it self-sow — a penstemon patch that's allowed to move around stays vigorous for decades.

Hummingbird Mint shrub

Hummingbird Mint

Agastache spp.

Height
24–36 inches
Width
18–24 inches
Sun
Full sun
Water
Low
Bloom
Midsummer to frost

Agastache covers the late-season gap that kills most pollinator gardens — it hits its stride in August when almost everything else is done, feeding bees and hummingbirds into October.

Like lavender, it demands drainage and hates winter-wet soil. Leave the stems standing over winter and cut back in spring.

Bee Balm shrub

Bee Balm

Monarda spp.

Height
24–48 inches
Width
24–36 inches
Sun
Sun to part shade
Water
Moderate
Bloom
Midsummer

The name is earned — the shaggy red and purple blooms pull in bumblebees, honeybees, and hummingbirds at once. It's the one plant on this list that appreciates a bit more water, so group it with your thirstier perennials.

Give it air circulation; crowded bee balm powders up with mildew by August.

Blanket Flower shrub

Blanket Flower

Gaillardia aristata

Height
12–24 inches
Width
12–18 inches
Sun
Full sun
Water
Very low
Bloom
Early summer to frost

The longest single bloom window on this list — red-and-yellow flowers from June until hard frost with almost no help. A native that treats poor soil and reflected heat as a feature.

Deadhead occasionally to keep it pumping, or leave late seed heads for finches.

Yarrow shrub

Yarrow

Achillea spp.

Height
18–30 inches
Width
18–24 inches
Sun
Full sun
Water
Very low
Bloom
Early to late summer

Yarrow's flat-topped clusters are landing pads for dozens of small native bee and beneficial insect species that the showier flowers miss. Ferny foliage looks good all season and shrugs off drought completely.

Cut spent heads back to a side bud for reliable rebloom into September.

  • Plant in drifts of three to five of one species, not scattered singles.
  • Group by water needs — the lavender/penstemon/agastache crowd on one drip zone, bee balm with the thirstier plants.
  • Skip landscape fabric in pollinator beds; most native bees nest in bare ground beneath the plants.
  • Leave stems and seed heads standing through winter — that's where next year's native bees overwinter.
  • Buy plants from growers who don't use systemic (neonicotinoid) treatments; ask before you buy.
