Golden Dyssodia
Thymophylla pentachaeta
A diminutive desert gem that covers itself in tiny golden daisies from late spring through fall, attracting butterflies all season.
A short-lived native (USDA zones 8-11) grown as an annual to tender perennial in the low desert; it blooms into fall, is nipped by hard frost, and reseeds to return.
AMWUA Notes
A low-water native that delivers a long season of miniature golden bloom and butterfly forage from easy reseeding.
Care Guide
Water every 1-2 weeks in the warm season; drought tolerant once established, it blooms for months on modest moisture with good drainage.
Lightly shear spent flowers to keep the tiny mound tidy and encourage continued bloom; otherwise it self-cleans and reseeds.
None needed; lean desert soil keeps it compact and floriferous.
Trouble-free.
A short-lived native (annual to short perennial) that blooms late spring through fall; sow in fall and let it reseed to renew the low golden carpet.
