St. Andrew’s Cross is a small, loose branching semi-evergreen subshrub. Its 4-petaled yellow flowers form the shape of an “X” or cross, for which it is named. Flowers bloom continuously from mid-summer through early fall, and grow best in full sun, but also tolerate partial shade. St. Andrew’s Cross prefers dry to moist, sandy to loamy soil, with a pH range from slightly acidic to slightly alkaline. It is relatively short-lived. Its native habitat includes dry open woodlands and upland slopes throughout the southeast, from Texas to New Jersey. The Coastal Plain of New Jersey is its northern-most range limit.

Wildlife Value: The bright yellow flowers attract bees, butterflies and other pollinators. Birds consume the seeds and use the small shrub for cover.
