Earlier this year I was given a bunch of these and they lasted ages. There were quite a few little off shoots which I cut off and trimmed and dipped in rooting dust. I laid them on a piece of newspaper at 2in intervals and covered with a light sprinkling of compost. Folded over the newspaper to contain the compost and rolled up tightly, fasten with an elastic band and tucked into a jam jar and kept watered. Most will root and the result is what you see here. When they have finished flowering I will replant them into individual pots. (which I should have already done but didn't get around to it) Free flowers! and a reminder of a spontanous gift from my lovely neighbour !
