I used germination sponges followed by cow pots. I also used a heating mat and grow lights. Really good success rate

- Rebecca H.Verified BuyerRated 5 out of 5 stars4/23/26Good germination
Did both a winter sow and traditional indoor sow after cold stratification and had good germination with both. Seedlings are looking happy. Picture of winter sown jug in April zone 7b.

- Tiffany T.Verified BuyerRated 1 out of 5 stars4/22/26Poor germination
Sprinkled out the whole packet and got one seedling. I've grown this every year and while it can be hard to get it to germinate in my climate, I've never had such poor results.
