I love cold hardy broad leaf evergreens and other exotic plants.
I'm trying to make a nice collection in my allotment for a third year.
This is what I bought yesterday - some sort of Agave (no label), Leucothoe, Pachysandra and Ceanothus americanus - concha
Here is my allotment. I have various evergreen plants there already from the last year:
like Pieris, bergenia crassifolia, Prunus laurocerasus, Musa Basjoo (I dig it out every autumn though),
several Rohds, Buxus, Ilex, Yucca and some other species I can't remember.
I'll list them later.
All of them proved to be cold hardy this winter with no shelter.
This winter was mild though - a few days down to 5F, mostly around 10-15F for 2-3 months.
