I grew some teasels two years ago: and last year grew some more from their
seeds.

They are doing fantastically well - very healthy. I noticed again the amount
of water which collects in the leaf bases - and then I saw a number of small
slugs and snails - drowned - in some of them. I wondered if they were acting
a bit like a Pitcher Plant - and were carnivorous in any way. A few searches
about teasels and I find that lo and behold they are.

Thanks for that, it's very interesting. I've often noticed the puddles
but never thought about them having a purpose.
