When we were at Malvern Show the wife bought 3 Trilliums, being a
Canadian from Ontario she felt she should have her national flower.
Now that we are home she has now asked me what I am going to do with
them, pity she didn't ask before buying.
Has anyone grown them for a prolonged period in pots?
I could plant them out under trees but she would then never see them
as she wouldn't be able to get close enough.

I'm pretty sure there was one in the alpine house at Harlow Carr last
time I was there, so growing in pots would seem to be possible.
