My son announced yesterday that he wanted to make a model alien from this Project X Alien Adventures book.

Obviously, I don’t have pipe cleaners. Or sticky eyes. I’ll buy some the next time I am in Cass Art.
There are a couple of things that I need to add to my shopping list – pretty much all plants. The slugs have now eaten all my petunias, most of the pelargoniums (bit of a surprise, that), the flowers (but not the plants themselves) of some alpine plant I’d put in there and all the bugle. The Greek oregano that I’d planted elsewhere is much reduced. However, they have also started eating the bastard creeping yellow buttercup. Which is a hideous weed – it is super invasive and is basically my nemesis. On balance, I think I prefer slugs to the buttercup weed.
The question is, what can I put in the flowerbed, given that the slugs have eaten everything but thyme? I absolutely love heather but my husband really wants small plants in that bed so they don’t clash with the box hedge. I’ve seen heather up Headon Warren that comes up to my waist so that’s out (I have no idea how you would prune heather). I would just bung some more lavender in there but my husband has got a bit sick of the endless lavender (to be fair, it is one of the only things the slugs won’t eat, apart from winter flowering heliotrope).
Perhaps sedum? More sea holly?
