Eryngium varifolium

Plant details

Eryngium varifolium is a compact sea holly, bearing small spiky flowers on sturdy, upright stems from July to September. It looks wonderful in gravel gardens and large herbaceous borders. The small flowerheads last well when cut for use in arrangements, and can also be dried.

For best results grow Eryngium varifolium in free-draining soil in full sun. Keep away from the edge of a border if children are present because the spines are very sharp.

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
