Native Americans chewed leaves and flowers of this plant to relieve sore throats, and chewed roots to relieve toothache. 
Plants established by seedlings can be started by sowing seed in containers in January and placed in a greenhouse. Seed should be covered lightly with soil and kept moist until germination. A layer of pea gravel can be applied to the soil surface to prevent seeds from floating. Seeds planted in this manner will begin germination about Day 7 and complete germination by Day 14.
