Spiky leaves and thistle-like flowers in beautiful shades of silvery grey through to cobalt blue. The leaves are dark green and the stems can be silver, green or greeny-blue. Its a fabulous one to pick for fresh flower arrangements and also dries beautifully too.
It's full of nectar richness for the pollinators in the summer months and come winter it looks gorgeous silhouetted against the bleak, cold skies.
Sea Holly grows well in coastal areas and gravel gardens. It likes gritty, well drained soil and full sun and is drought tolerant.
But despite being a hardy perennial it will suffer in the winter unless it's given a good straw mulch to help to keep from rotting.

I have ordered many seeds from this website, the delivery is reasonable and so are the seeds. I get fantastic germination and am no expert. I have tried other seed companies and nothing compares. This is a very safe bet and one that you won’t regret.
Completely a beginner but they have germinated after a couple of days and seedlings seem to be coming along nicely, very healthy and happy little plants … seeds came in addition to sow a long package and all beautifully presented … will be a repeat customer
