I took a large stem cutting today and have put it in water, so it is not yet rooted, but I have successfully propagated them this way. I'm giving it to anyone who can collect it in the next 7 days.
I don't know the name of the variety because it came from a friend's daughter who lives in Canada. It has lovely leaves and shell pink flowers in the summer. It could go out in the garden in summer in the shade. But it's a risk as it's not yet rooted so take your chances, and bring a plastic bag to take it home in.
Please let me know when you can collect it from Northfield, if you are interested.
