Santa Rita Mountain Draba: A Rare Gem for the Specialized Native Garden
Meet the Santa Rita Mountain draba (Draba petrophila), a charming little perennial that’s as tough as the rocky mountain slopes it calls home. This diminutive native wildflower might not win any height contests, but what it lacks in stature, it makes up for in character and ecological value.

As a perennial, it returns year after year, forming neat little rosettes that burst into bloom with clusters of tiny white flowers in early spring.
Santa Rita Mountain draba grows exclusively in Arizona and New Mexico, where it has adapted to life in the challenging mountain environments of the Southwest. This limited geographic distribution makes it a true regional treasure.
