Also need to know what this is please. It's got wierd shaped leaves, almost like a rubbery feel and not sure what colour flowers. It also spreads and grows anywhere.

Looks like a sedum to me.  ???

Definitely Sedum.

Sedum reflexum (I think), used to be called Sedum rupestre.

Not a euphorbia then?

Sedum album is a possibility.
Being a bit nit-picking, but something to indicate scale would help in identifying plants. I usually put a coin down next to the plant, it helps no end if one has a good idea of the size of leaves and flowers etc. :)

Thankyou so much,
Sedum reflexum it is! Just done a search on askjeeves and it came up everywhere, apparently has yellow starry flowers in summer. Looking forward to them  :D

Yup. Will grow on the thinnest of layers of soil, e.g., the moss on my porch roof!

Yes it has very pretty yellow flowers, its lovely in the right place.
