Cultivation Details
Andropogon gerardii has a wide native range, growing from the prairies of southern Canada to higher elevations in the tropical regions of MesoAmerica. In the temperate zone it is found in areas where annual daytime temperatures are within the range 10 - 20°c, but can tolerate 3 - 28°c[1]. When dormant, the plant can survive temperatures down to about -15°c, but young growth can be severely damaged at -5°c[1]. It prefers a mean annual rainfall in the range 700 - 1,200mm, but tolerates 350 - 2,800mm[1]. Requires a light porous sandy soil in full sun[2]. Easily grown in average, dry to medium, well-drained soils in full sun[3]. The plant is tolerant of a wide range of soils and growing conditions[3]. It puts out lots of growth in moist, fertile soils, but is less apt to topple in dryish, infertile soils[3]. It prefers a pH in the range 5.5 - 6.5, but tolerates 4.5 - 7.6[1]. Established plants are very drought tolerant[3]. The plant freely self-seeds in optimum growing conditions[3]. It develops an extensive root system and is somewhat slow to establish, but, once established, is easy to maintain[3]. A very ornamental plant, it forms large clumps, spreading by short stolons[2]. Various cultivars have been developed, many of these especially for use in rehabilitating prairie land with native grass species[4].
Propagation
Seed - surface sow in early spring in a greenhouse. When large enough to handle, prick the seedlings out into individual pots and grow them on for the first winter in a cold greenhouse. Plant out in late spring or early summer, after the last expected frosts. Division in spring.
