Crassula ovata or 'jade plant', I have it for six years now.
It was a tiny cutting when I got it, it has grown unruly as I don't cut it to shape it.
I've taken few leaves and tiny branches to propagate this one too
along with several sedum leaves and cuttings.
I've been looking for this plant (crassula umbella) for ages but never managed to find it,
sometimes when you stop searching for something you'll find it.
