I have an Arum lilly in a pot, given to me this year, only 1 flower
but grown on very well and now quite 'dense'
I am wondering what to do for the winter as I would like to keep it in
the pot, all the time. Also a bit of root broke off which I put into
another pot......... forgot about, and is now poking leaves through. I
would like to plant this in the garden (next year?) ANY advice please.
