Near my composter they have eaten chrysanthemum and millfoil and left perennial geraniums, veronica and day lilies.(Geranium sanguinium is specially nice at the front of a border) For annuals they have eaten sweet sultan and more or less left cosmos and nasturtiums. They don't touch marigolds or nepeta. Hope this helps.

now they adore any of the marigolds i put out. do you mean the calendula ones or the tagetes type?
havent found anything sacrosanct this year :o(

I can't grow marigolds at all - they attract all the slugs in the county!! I used to find impatiens fairly resistant, then after a few years, they started on them too. Trial and error is possibly the only way to find out - or ask your neighbours, they may entertain the same slugs! (They are currently enjoying my runner beans). I think they - the slugs, that is - are thriving in the wet conditions.

The big calendulas and their reverted seedlings seem to be OK. the African ones and the tagetes types seem to be the delicious ones. I had some lovely cream ones last year interplanted with some ageratums and it was meant to be gorgeous, but what I got was ageratums and stalks.

Sounds familiar!

Thank you all so much for taking the time to reply. I'll keep everything crossed that they are enjoying themselves so much in the composter that they don't come out.
Melchisedec - I smiled when you mentioned checking with my neighbours as one side has flagstones and the other has laid loose stones, maybe the slugs lived there once upon a time!
Thanks again!

Perhaps that's why they're all in your composter!!!
