Rhizomatous Bluestem (Schizachyrium rhizomatum)
Rhizomatous Bluestem (Schizachyrium rhizomatum)
Description: A slowly spreading rhizomatous grass, with rather stiff blades, forming dense patches with time. Leaves 1- 2 ft tall, with flower spikes to 4’.
Natural Habitat: A frequent component of mesic/hydric pine rocklands in Miami-Dade, and marl prairies; endemic to peninsular Florida.
Planting and Care: Grows on limestone substrates with little soil, prefers moist habitats but grows (more slowly) in drier sites, and tolerates drought once established.
No other special care; once established, it usually does well.
In mixed plantings, keep well away from shorter wildflowers, such as Scale-leaf Aster.
Pros: A medium-height grass ideal for pineland restorations. The patches are dense enough to suppress weed intrusion. The spreading habit contrasts with most pine rockland grasses, which are “clumps”. Dried leaves provide further contrast and a “natural” look, but can be cut back or mowed yearly for a more tidy appearance.Tolerates drought and poor-quality soil.
Cons: It can spread and overshadow small herbs and wildflowers. AVOID planting close to smaller wildflowers.
