Homeowner Growing Tips

Grow in shade to part shade, or dappled sun. Amend soil with compost and lime; prefers alkaline soils. Prefer consistant moisture during the growing season, but excellent drainage is required to overwinter successfully. May be divided, if necessary, after blooming. Does not do as well in hot, humid climates.
