PropagationPropagation Material: Seeds
Description: Very easy to propagate from seed in spring or fall though a fall seeding is recommended. Seeds do not have to be treated but may benefit from a period of stratification. Plants from seed usually bloom the second year. Be sure the seed is in good contact with the soil by lightly raking it into loose topsoil. Seeding rate is two to four pounds per acre. There are approximately 1,230,000 seeds per pound.
Seed Collection: Seed is available commercially or can be collected in late summer. Collect seed from several plants to increase the spectrum of color. If possible, collect seed from plants with solid yellow ray petals to contrast with plants with reddish-brown ray plants.
Seed Treatment: Stratify at 40 degrees for 9 weeks.
Commercially Avail: yes
Maintenance: Supplemental watering may be required if the winter and spring are unusually dry. Watering in summer often extends the flowering period. After flowering ceases, allow seed to completely mature (let cones become dry and brown) before mowing for reseeding or collecting seed to plant in another area.
