Top 10 Native Plants for a Thriving Denver Xeriscape
Creating a successful xeriscape in Denver means working with nature—not against it. By choosing native plants that are already adapted to the semi-arid climate and USDA Zone 5b, you’ll enjoy a beautiful, low-maintenance landscape that supports pollinators, conserves water, and stands up to Colorado’s fluctuating weather.
Whether you’re replacing a traditional lawn or simply want a more sustainable landscape, these 10 native perennials, shrubs, and trees will help you build a xeriscape that thrives in Denver’s unique environment.
🌼 1. Rocky Mountain Penstemon (Penstemon strictus)
Type: Perennial
Bloom Time: Late spring to early summer
Why It Works: This stunning blue-purple flower is a Colorado classic. It’s drought-tolerant, attracts hummingbirds, and adds vertical interest to any garden. Ideal for sunny borders and dry slopes.
🌿 2. Blue Grama Grass (Bouteloua gracilis)
Type: Perennial Grass (and CO’s State Grass)
Bloom Time: Summer
Why It Works: As one of the most iconic prairie grasses, Blue Grama is perfect for replacing thirsty turf. It’s low-growing, soft underfoot, and creates a meadow-like feel in full sun.
🌸 3. Blanket Flower (Gaillardia aristata)
Type: Perennial
Bloom Time: Late spring through fall
Why It Works: With vibrant red and yellow blooms, this native wildflower adds bold color and long-season interest. It thrives in poor soils and is loved by bees and butterflies.
🌱 4. Rabbitbrush (Ericameria nauseosa)
Type: Shrub
Bloom Time: Late summer to fall
Why It Works: This hardy shrub features silver-gray foliage and bright yellow blooms in fall—when most plants are fading. Perfect for sunny, dry areas and roadside plantings.
🌼 5. Prairie Coneflower (Ratibida columnifera)
Type: Perennial
Bloom Time: Mid-summer to early fall
Why It Works: Also known as Mexican Hat, this wildflower adds texture and whimsy. It thrives in full sun, well-drained soil, and pairs beautifully with native grasses.
🌲 6. Pinyon Pine [a.k.a. Piñon Pine] (Pinus edulis)
Type: Small Evergreen Tree

🌸 7. Showy Milkweed (Asclepias speciosa)

🌿 8. Big Sagebrush (Artemisia tridentata)

Why It Works: Known for its silvery foliage and iconic scent, Big Sagebrush offers excellent erosion control and low-water performance. Use it as a bold anchor in dry gardens or hillsides.
🌼 9. Sulphur Flower (Eriogonum umbellatum)
Type: Groundcover Perennial
Bloom Time: Early to mid-summer
Why It Works: This hardy groundcover spreads low and wide, with bright yellow blooms that pop against gravel or mulch. It’s especially well-suited for rock gardens and berms.
