Growth Chart
Hardiness Zones: 4 to 7 Light Requirement: Full to partial sun Soil Type: Rich, loamy, moist Sow Depth: 1/4 inch Plant Spacing: 12 to 24 inches Germination Note: Cold stratification required Stratification Time: 30 days Bloom Time: June through July Growing Tips
Direct sow in late fall by planting the seeds just below the soil's surface. For earlier planting, mix seeds with moist sand and store in the refrigerator for 30 days (cold stratification) before direct sowing.
A Note on Cold Stratification
These seeds require cold, moist stratification. To naturally stratify the seeds, plant outdoors late fall on a weed-free site and allow seeds to overwinter.
To artificially stratify the seeds, place the seeds and a moist medium (such as a damp paper towel, coffee filter, sand, or vermiculite) in a labeled, sealed plastic bag and store in a refrigerator (33-40°F) for the amount of time noted on the growth chart before sowing.
