Sweetheart plant..

This sweetheart plant belonged to my mum and is at the very least twenty five years old and is probably taken from a cutting of a plant that was very much older. I remember, even a child, that we always had one of these growing prettily in a plant pot.
Since my mum passed away in February I would hate to lose this plant and so, to be safe, I regularly take cuttings so that I always have one growing !
