About this plant
Andropogon gerardii 'Red October' is an ornamental grass with bold, reddish foliage that intensifies in color as the season progresses. The narrow, upright leaves start green in the spring but transform into rich hues of red and burgundy by late summer and fall. In late summer, this cultivar produces airy, tan flower panicles that add texture and movement to the landscape.
This variety of big bluestem thrives in well-drained soil and full sun, where it grows into a tall, upright clump. Once established, 'Red October' is drought-tolerant and low-maintenance, making it an excellent choice for xeriscapes, naturalized areas, or prairie-style gardens. Its ability to withstand poor soils and dry conditions adds to its appeal for gardeners seeking a hardy, low-care plant.

Design tip
Late flowers extend the season, so set it behind or beside plants that finish in midsummer. In full sun it holds its shape best, and grouping several together keeps the color strong enough to be seen from across the garden.
Where to see it
This plant can be seen at the Center for Urban Horticulture and in the perennial border at the Bellevue Botanical Garden.
