Description: I. rubra was the most successful of over twenty individual species field-tested at the National Wildflower Research Center in 1984-85, yielding an average of over 200 seedlings per square meter when seeded at the recommended rate. Propagate by sowing seed in fall. A fall seeding recommended. Be sure the seeds are in good contact with the soil by lightly raking the seed into loose topsoil. Since it is a biennial, it is recommended that you plant two consecutive years in order to produce flowering stalks each year.
Seed Collection: After flowering ceases, allow seeds to completely mature before moving for reseeding or collecting seed to plant in a new area.
Commercially Avail: yes
Maintenance: The first year of growth will produce a ferny rosette, followed by a flower spike the second year. When the spike has bloomed out, cut it off, and new spikes will be formed.
