Bouteloua gracilis

Blue Grama is a warm-season grass in the Poaceae family. It can get anywhere from six inches
to two feet tall and is very drought resistant, but it will use less water if let grown taller, as it
provides shade. It is one of the most drought tolerant grasses, as it can survive on as little as
seven inches of rain a year! Since it likes rocky soils, it would do well in a rock garden. Blooms
with a purple tint appear on this plant in summer, resembling mosquito larvae. Blue Grama is a host plant for several species of Skipper butterflies.
