Seen growing out the top of a 10ft high stone wall in Empingham. Height approx up to 1 foot.
I don't think so - but I'm not sure what it is! I am wondering if it Corydalis cheilanthifolia? - a plant I have occasionally grown in the garden. The top of a wall would be a good habitat for it.
Thanks Sue, i will check that out and also keep an eye on the plant to see if it flowers?
