Cultivation details

Thrives in full sun or dappled shade on rich, moisture-retentive soils sheltered from strong winds[200]. The plant is heat tolerant in zones 9 through 5. (Plant Hardiness Zones show how well plants withstand cold winter temperatures. Plant Heat Zones show when plants would start suffering from the heat. The Plant Heat Zone map is based on the number of "heat days" experienced in a given area where the temperature climbs to over 86 degrees F (30°C). At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 (no heat days) to 12 (210 or more heat days). For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a clumper with limited spread [1-2]. The root pattern is fibrous dividing into a large number of fine roots [1-2].

I am looking for information on the production, vegetative and seed, for Chasmanthium latifolium. Nursery production and field scale production for seed and plant increase. This is for local ecotypic establishment of native and locally collected seeds. Information on row and plant spacing, sun or shading for optimum seed production in a field setting.
