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.
