Sowing and Growing Notes
Sow Blanket Flower in fall or early spring onto a firm, weed-free surface in full sun with sharp drainage. The seed needs light, so press it in rather than covering it. It does not require cold stratification, unlike the milkweeds and penstemons, so a spring sowing works fine. Keep the surface damp until seedlings establish, then reduce water sharply.
Water: Low
Sun: Full Sun
Soil: Sharply drained; lean soil, rots in heavy wet ground
Mature size: W 1'-1.5' x H 1'-2'
Maintenance
Blanket Flower often blooms in its first year from an early sowing. Once established, deadhead through the season to prolong bloom, and cut it back fully in fall if you do not want volunteers, since Gaillardia is an exception to the leave-a-third rule. Let some seed drop if you want the stand to renew itself, because individual plants are short-lived.
