Desert Coreopsis

Name: Desert Coreopsis
Brand: Outdoor Dream Builders

Coreopsis bigelovii

Sheets of golden yellow wildflowers transform the desert floor in early spring, attracting butterflies by the dozen.

A cool-season annual in USDA zones 9-11; fall-sown for early-spring bloom in the low desert, it completes its cycle before summer heat and relies on reseeding to return.

AMWUA Notes

A low-water spring wildflower that carpets bare ground in gold from a single fall sowing.

Care Guide

💧Watering

Water every 1-2 weeks through the cool growing season; winter rains often supply most of what it needs, and it dislikes soggy soil.

✂️Pruning

No real pruning — as a spring annual it simply finishes and dries after bloom; leave seed heads to reseed before pulling the spent plants.

🌱Fertilizing

None needed; lean desert soil produces the best flower display.

🛡️Pests

Trouble-free.

☀️Seasonal Notes

A cool-season desert annual; sow seed in fall for a golden early-spring display, then let it dry and reseed as temperatures climb.

Soil, Feeding & Propagation

🪨Soil

Lean, sandy or gravelly, well-drained desert soils; poor soil yields the best bloom.

💧Drainage

Needs well-drained soil.

🌱Nutrient Needs

None — thrives in lean desert soil without fertilizer.

🌰Propagation

Seed; broadcast-sow in fall (cool-season) and let it dry and reseed.

📐Spacing

1.5 ft

🌳Roots & Placement

Minimal; a shallow-rooted spring annual that relies on reseeding to return.

Placement Tips

•Broadcast-sow across open ground in fall for a sheet of golden spring color.
•Mass with other spring wildflowers for a layered bloom rather than isolated plants.
•Let it dry and drop seed before cleanup to guarantee next spring's show.
•Full sun; a classic component of a low-desert spring wildflower mix.
