Well it can, but you run the risk of losing it, because it's more exposed. And it is lovely in a tall tub, trailing down the outside, but it's up to you - I wouldn't put in the garden because you'd need to have some kind of framework to attach it to, or it'll sprawl all across the ground, but that's just my preference.

I have two in my front garden.
One is ground cover and one trails over a wall, they're great plants !

Oh, to live in the mild south west, as you do, Louise! Not sure where Brackets lives though...

:-))
I'm always thankful i live here Bamboo, i take a lot of liberties with my plants and planting and they've mostly always paid off ;-)
I wouldn't get away with it anywhere else, i know !

Missed this one. My parents had C. mauritanicus growing at the base of a south wall where is sprawled out into a nice patch of low stems, leaves and lovely blue flowers in SE Northumberland for at leat five years. Given the right spot it is a great plant.

Thanks everybody!
