Best Flowering Shrubs for Colorado

Here’s our roundup of the best flowering shrubs for Colorado, hand-picked for beauty, resilience, and local flair. These shrubs for Colorado thrive in zones 3-7, perfect for our Front Range and beyond.

1. Spirea (Spiraea)

Spirea is a crowd-pleaser for Colorado gardens. This compact shrub, growing 2-5 feet tall, bursts with white or pink blooms in spring and early summer. Varieties like ‘Goldmound’ add golden foliage for extra pizzazz, while ‘Grefsheim’ offers cascading white flowers. Spirea loves full sun, tolerates drought, and needs minimal pruning—just a trim after blooming to keep it tidy. It’s perfect for borders, rock gardens, or foundation plantings in Colorado Springs or Boulder. Bonus: its fall color shifts to yellowy-green, adding late-season charm.

2. Potentilla (Cinquefoil)

Looking for spring blooming shrubs yellow? Potentilla’s your star! This tough, low-growing shrub (2-3 feet) blooms from early summer to frost with buttercup-yellow, pink, or white flowers. ‘Gold Drop’ is a favorite for its sunny vibes and long bloom time. Native to tough climates, Potentilla thrives in Colorado’s dry, sunny conditions and poor soils. It’s low-maintenance, deer-resistant, and great for hedges or mass plantings in Aurora or Littleton. A light spring prune keeps it blooming strong.

3. Lilac (Syringa)

Nothing says spring like the sweet scent of lilac! These classic flowering bushes in Colorado grow 5-12 feet tall, with purple, pink, or white blooms in May. ‘Dwarf Korean Lilac’ is ideal for smaller yards, staying compact at 4-6 feet. Lilacs love full sun and well-drained soil, handling Colorado’s cold winters like champs. Plant them near patios in Loveland or Greeley to enjoy their fragrance. Prune right after blooming to shape and boost next year’s flowers. Watch for aphids, but they’re generally easy to care for.

4. Serviceberry (Amelanchier)

Serviceberry is a three-season superstar. In spring, it’s covered in delicate white flowers, followed by edible purple berries in summer that birds adore. Come fall, its leaves turn fiery red or orange. Growing 6-15 feet, ‘Autumn Brilliance’ is a top pick for larger spaces in Fort Collins or Parker. This native shrub loves part shade to full sun and tolerates drought once established. It’s perfect for naturalized gardens or privacy screens in Colorado’s foothills.

5. Viburnum

Viburnum shrubs are a Colorado gem for year-round interest. ‘Korean Spice’ offers fragrant pink-to-white flowers in spring, while ‘Summer Snowflake’ blooms white from spring to summer. Both grow 4-8 feet and feature red berries and stunning fall foliage—yellow to burgundy. Viburnums thrive in partial sun and moist, well-drained soil, ideal for Denver or Arvada borders. They’re pest-resistant and attract wildlife, making them a low-fuss choice for shrubs in Colorado. Prune lightly after flowering.

6. Apache Plume (Fallugia paradoxa)

A Colorado native, Apache Plume is a xeric champ. This 3-6 foot shrub boasts delicate white flowers in spring, followed by feathery pink seed heads that look like tiny pom-poms. It’s drought-tolerant, loves full sun, and thrives in rocky soils—perfect for xeriscape gardens in Grand Junction or Castle Rock. Its wispy texture adds softness to landscapes, and it needs almost no care. Trim lightly in spring for shape, but let it grow wild for a natural vibe.

7. Butterfly Bush (Buddleia davidii)

Want a pollinator magnet? Butterfly Bush delivers with long spikes of purple, pink, or white flowers from summer to fall. ‘Miss Molly’ stays compact at 4-5 feet, ideal for smaller yards in Lakewood or Longmont. It loves full sun and well-drained soil, and pruning to 10 inches in spring boosts blooms. Note: some areas consider it invasive, so deadhead spent flowers to prevent spreading. It’s a vibrant pick for best flowering bushes for Colorado.

8. Nanking Cherry (Prunus tomentosa)

One of the first to bloom, Nanking Cherry lights up spring with pinkish-white flowers, followed by tart red cherries that kids and birds love. Growing 6-10 feet, it’s great for hedges or windbreaks in Colorado Springs or Pueblo. This hardy shrub thrives in full sun, tolerates drought, and needs minimal care. Prune older branches to encourage blooms and fruit. Its edible cherries make it a fun, functional choice for shrubs in Colorado.
