I've always believed the evergreen type are not hardy in the UK outside, pot
culture only. My ones grown for seed are the other type and they are hardy
of sorts but position is everything.

I'm surprised at the comments on good drainage; because in NZ and
Madeira I've seen wet drainage ditches heavily colonised by agapanthus ,
and several varieties of deciduous types grow very well in my high-
rainfall garden, in places that are often water logged. I've not lost
one in 11 years here.
I don't give them any winter protection at all. We do have relatively
mild winters (just a few degrees of frost) but they have survived a
spell of several weeks cold enough that ice on the pond never melted.
