This spectacular perennial hybrid has 18-inch-tall spires of buttery yellow flowers in late spring and beautiful blue-green foliage throughout summer. Tough, exceptionally drought tolerant, and extremely long-lived, it's the southern substitute for the much sought-after lupine.

A member of the conifer clan, Ephedra equisetina is commonly called bluestem joint fir due to its finely textured blue stems. In spring, it features a conspicuous froth of yellow blooms that are often followed by red berries. It is perfect for naturalized areas since it reliably spreads.
