Spoon leaved stonecrop

The flowers look similar to the one that grows like a weed around here, especially along a one mile stretch of dual carriageway. I grabbed some last year and tucked it into my wall and it seems to have taken well.
Are those leaves very small?

Yes, it's very small. Those little rosettes are about the size of a 5p. The green spikey leaves that are poking through belong to another plant though. This one is just the grey rosettes and the yellow flowers. It's growing in a patch that's like a little rockery (but it's really just a pile of rubble at the moment) so I think they must like little crevices.

Ah - the foliage is huge then compared to my weed variety!

That comment above which is credited to Iciar was actually by me - for some reason it happens from time to time.

I thought mine were really small but yours must be tiny! How cute!
The rosettes on mine are probably about half and inch at most in diameter but most are around 1cm or less.
