Sea Holly not thriving

Hello, I'm a totally new gardener.  And I've not got a clue.  We have inherrited an old very clay garden.

At the moment I'm growing plants in pots in the hope that we can get the ground suitable for planting them next spring.

I have a sea holly and just planted it in ordinary compost that we had in a pot, but it's not thriving at all, and slowly the "flowers" are turning brown, and it's not happy at all.

And I have no idea what to do.

    is this Eryngium maritimum, sea holly as seen on beaches, or one of the garden species? They all like good drainage, but this one more than many I've grown,

    The brown isn't just the flower dead and seeds forming is it. How about a photo?

  • I'll get a photograph and find the full name of the plant tomorrow.

    Don't try an upload too large a pic tomorrow, I reduce mine to 30% and they upload. People are always having problems with large files

    It's Moroccan Sea Holly  Etyngium varifolium

    Even though I've put a copper strip round the pot the slugs have got the bedding plants that were in it, and I wonder if they've got it the Sea Holly too.

    I thought with it being silver and spiny they'd leave it alone!  Never underestimate my slugs obviously.

    SS abseil, they'll drop in from overhanging plants and adjacent pots - I learned that lesson the hard way image

    Did you keep it moist for the sake of the bedding plants? This one grows on some of my poorest, driest soil. It doesn't look great. I wouldn't worry about brown flowers, there will be more next year. Are there any live leaves left at the bottom? they're more important

  • Not really, I think the slugs have had them.

    I'll move the pot away from the others and see if that helps, and not water.

    Hopefully keeping the slugs off it will help.

    Perhaps not the plant for my garden, I've got clay soil, next pot along is a Echinops, which is doing much better.

    Yes, put it up a corner and ignore it. No water except what drops from the sky. Probably better in a pot if you have clay soil but very quick draining compost
