Ratings & Reviews
So far I haven't had any luck with germination. I have tried not stratified and cold stratified methods. I generally have a high success rate with germination as I am fairly experienced. I will try direct sow in the fall. Really hoping I can get this plant to grow as it looks gorgeous.
