Tammy, I want them sooooooo bad! I've been trying for two years and only had one success from 7 bareroot plants I bought from someone (can't remember what catalog) . It bloomed that summer, then didn't come back the next year. Then I tried seeds , twice, and got nothing at all. I did try starting them inside, I have a lil mini fridge for them. I know it says not to , but I was trying them in peat pots and I figured if they did sprout I could just cut the bottom and bury them in the peat pot???? Anyway, I'm going to try direct sowing this fall again. I'll let you know .............

I have the same feelings about chinese lanterns and money plants so I know how you feel.

The germination instructions change quite a bit depending on the type of sea holly you are growing so make sure you get the botanical name for your type and then follow the directions very carefully. Pay particular attention to the "light sandy soil" I don't think these will grow if you try to start them in starting potting soil. Or regular potting soil either.
