Cultural Information

Propagation is best from seeds. Collect the capsules when they become wrinkled but before they fall from the plant. The capsules should dried then crushed to release the seeds. Fresh seed should be planted in fall (in cool soil). Cold/moist stratification (90 days at 33-40 degrees F) improves germination (Phillips 1985, Steffen 1997). There are about 7,568,000 seeds/lb and the recommended planting rate is 0.5 lbs/acre. Seedlings are easily transplanted and often bloom 1-2 years after germination. Clumps may be divided in early spring but require moist conditions. (Phillips 1985). An early spring wildflower that reseeds readily in good garden soil.

Habitat

Meadows, grassy places, damp woods, deciduous woods, moist prairies, low, wet areas, sandy or rocky acid soils.
