Do your part to help the beautiful Monarch butterfly with this preferred food source of their caterpillars. Bright pink to red vanilla-scented flowers appear in June and July. Seeds must under go the process of stratification before sowing to ensure good germination, below are some helpful tips for stratification. Full sun. Perennial. Hardy to zone 4.
|Average Seed / oz||Seed / 100' Row||Average Yield / 100' Row||Days to Harvest|
|Planting Season||Ideal Soil Temp||Sun||Frost Tolerance|
|Fall||65-80°F||Full Sun||Lightly Tolerant|
|Sowing Method||Seed Depth||Direct Seed Spacing||Seeds Per Packet|
|Mature Spacing||Days to Sprout||Production Cycle||Seed Viability|
These North American native milkweeds are hardy perennials that will tolerate full sun to partial shade and thrive in a wide variety of soils.
For best results, expose seeds to moist, cold conditions (stratification) prior to sowing. For cold stratification, place seeds in moist potting soil or sand and store in a refrigerator for 4-6 weeks. After stratification, sow seeds in containers or direct seed outdoors after the danger of frost has passed. Sow seeds 1/8-1/4" deep and 6-8" apart. Optimal soil temperature for germination is 65-80˚F. Seeds will sprout in 10-28 days. Thin seedlings so that mature plants are 24-36" apart.
