I'm assuming that this is an alpine of some sort as I, *ahem* picked a tiny stem from the rock gardens that our local council are constructing near the beach. I popped it into a pot and forgot about it. This was a month a go. It was dark purple then and tightly closed up. I noticed today that it had undergone a complete transformation. not only from purple to green but it's unfurling from what were closed up leaves. Does anyone know what it is? A type of sedum maybe?
