How to plant: Break off the seeds from buds in the package. Wet the area where seeds will be planted. Scatter seeds shallowly in a bright, sunny area in late fall for blooms in late spring or in late winter for summer blooms. Step on the seeds to ensure they are shallowly dug into the dirt.
 
Recommended: Prepare the area for seed sowing by removing weeds, and adding a thin layer of healthy soil mixture of native soil, compost, sand, and garden soil for planting. Check that the soil is healthy, loamy, medium-moist, and well-drained. Water when soil dries; keep the seeds moist, but do not overwater until they are sprouted. Recommend to mulch sprouts in winter. Flowers will go dormant in winter and mulch protects them. Blooms March through October.
