- These seeds require a period of cold stratification to germinate. If you do not simulate winter conditions, the germination rate can be quite low. To cold stratify, place seeds in moist soil and refrigerate for 18 days prior to planting. Seeds can also be planted in the fall, as long as soil temperature will drop into the 30's, to provide natural stratification.
- Plant seeds just below soil surface in full sun and maintain moist soil until seedling is established. Germinates best if soil is kept around 70 degrees. Germination can take 3-4 weeks, so please give your seeds the attention they need during this time by keeping the soil warm and moist until the seedlings are established.
- Grows 3-4' tall with 3-4" purple flowers. Can take until the second year to bloom when grown from seed
