Big Bluestem (Andropogon gerardii 'Red October') is easily grown in average, dry to medium, well-drained soils in full sun. It is tolerant of a wide range of soils and growing conditions but tends to flop in rich moist soils. This ornamantal grass is a tall, Kansas native, perennial, warm season grass that dominates much of the tall grass prairie extending into the Flint Hills. In fact, Big bluestem, Indiangrass, Little bluestem, and Switchgrass comprise 75% of the species in this ecosystem. It may be grown as an ornamental grass because of its attractive foliage which changes color seasonally along with its good architectural height and its interesting flower/seed heads. Andropogon gerardii 'Red October' is primarily distinguished from the species by its slightly shorter height, deeper green summer foliage and brilliant scarlet red fall color. An excellent garden performer with a clumping form and upright habit. Leaves emerge deep green with red highlights in spring, remain green through much of the summer, change to purplish-red to purple by late summer and finally turn a vivid scarlet red after first fall frost. Burgundy red flowers bloom in August. Plants typically grow to 4-5' tall.
