Martin, you took the words right out of my mouth!
Yes, Benny, I would most certainly recommend Glendoick Gardens, they have a selection of vireyas I would love to grow! I would need to keep them under glass, perhaps with a little extra frost protection as well, here in Aberdeen , two miles form the cold north sea! I have no room, so I can only wish! If you have a conservatory or sun-room attached to your home many of them will grow there very happily, i would think.
