24-28 tall x 15 wide. A superb native grass, Bouteloua curtipendula (Sideoats Grama Grass) is a delight in the xeric garden. This grass will provide year-round visual interest in waterwise gardens, and is not appetizing to deer. It grows best with full sun and thrives in any soil type including clay. Established plants are quite xeric and a fine choice for very dry sites. Mature plants have an attractive vase-shaped growth habit that mixes in nicely with other native late season bloomers like Rudbeckia, Ratibida, and Salvia azurea.
