Description

Andropogon ternarius is a very ornamental, tough bunchgrass. Forming dense clumps 1' in diameter, it reaches a height of 4' when in bloom. The leaf blades are slender, and develop a blue cast as they mature. The slivery-white seed tufts are about 2" long and split in two, hence the common name splitbeard. They emerge all along the stems, which is an unusual feature among grasses, and are truly spectacular in fall when they contrast against the stems and leaf blades that by then will have developed vivid shades of orange purple and red.

Cultivation

Splitbeard bluestem is adapted to dry, infertile soil and lots of sun. Can be used as a specimen, planted in large groups, or incorporated into a native meadow. It provides strong visual interest well into winter, and shouldn't be cut back until early spring, before new growth emerges. Zones 5-10

Propagation

Propagate from seed. No treatment is required.
