I haven't had success with these yet. But if I ever get where I can try them again I will. I've gathered the following information so far but I could definitely use any hints tips or corrections you have as far as dealing with these plants.
Scientific Name of Plant: Eryngium alpinum Common Name of Plant: "Alpine Sea Holly" Indoor/Outdoor Plant: Outdoor Days to Germination: around 89 days USDA Growing Zone: 5 to 9 Conditions for sprouting: Direct sow only. Place seeds on top of the soil and press lightly so they do not move when watering, some types need light to germinate. Needs a soil temperature of 68F or cooler. Chilling seeds may help with the germination but is not considered necessary. Mature Plant Care: Lighting requirements: Full Sun Fertilizer requirements: Average Watering requirements: Can take drought conditions Soil requirements: Light Sandy Soil pH: Dead Heading: Only if not harvesting seeds Pinching flower spikes: No Plant spacing: 18 inches Pruning times and amounts: Conditions for Blooming: Plant Life Cycle: Perennial Propogation: Propagate by division, seed or root cuttings all done in the spring.

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.

Good point, Tammy, I never thought about that! I knew they liked growing in the sandy soil, I just didn't think about them starting in sandy soil. I think I have just the right spot for them ..............I'll keep you posted .
