Mystery - very useful - plant

The plant was given to me by a sweet old lady and she had no idea what it was beyond some vague thought that "it may be some sort of Sedum"

It's evergreen. It flowers lots - fresh and yellow - in March, April and May. You can see some late flowers on the second photo.

It is so easy to propagate. Cut a bit off, make a hole with a pencil, stick it in. Bob's your uncle.

I use it as a box substitute! It's happy trailing down containers. Those containers were each made with a handful of two inch cuttings about two years ago.

Google reckons -

Sedum Kimnachii
though the name sedum has been changed to something unnecessarily complicated

 

Thanks @Pete8 I should have thought to have used google.

This looks like quite a good on line resource
