Biting Stonecrop is common and widespread throughout the UK and Ireland.
This low-growing member of the stonecrop family is an evergreen. The leaves have a sharp taste, from which it gets its Latin name 'acre', meaning sharp.

Biting stonecrop is found in dry, rocky places including stone walls. It also grows in sandy soils. The flowers appear in June and July.
English Stonecrop, similar in size and general structure but with smaller leaves than biting stonecrop, has white and pink flowers and is often found on cliff tops as well as on drystone walls.
