I bought an hosta last year planted it in a tub in the yard and it grew great lovely leaves and flowers, and the slugs didnt bother it at all.I just let it die off then trimmed it back,didnt know if that was the right thing to do,but it has started to grow again.
The thing is it looks as if their is three growing now in the same tub, can someone tell me if these self seed, their is definitely more than one growing.

thank you.
