Plant details

The purple flowers of Eryngium varifolium open on top of sturdy, upright stems from July to September. The plant requires free-draining ground and a sunny position. Like all eryngiums, the tiny flowers are packed together in a tight cluster, surrounded by a ruff of spiny bracts. Keep away from the edge of a border if children are present because the spines are very sharp. The long, sliver bracts of Eryngium varifolium looks wonderful in gravel gardens and large herbaceous borders. The small flowerheads last well when cut and can also be dried.

The feature on the Sea Holly is good, I have tried for 2 year now to grow it from seed with no success at all, which is a bit worrying as I am having a lot of success with everything else although I am only learning and new to all this. So I am really disappointed that It didn't grow again, any suggestions for me. I'm determined to get it to grow.

Hope you can help me
