Wall Pepper, or Biting Stonecrop, is a small evergreen perennial. The flowers are star-like with five petals and are a bright yellow. The leaves are small, thick, fleshy and have a peppery taste. The creeping stems make the plant form an attractive, yellow-flowered mat. Wall Pepper grows on mortared walls, poor soil, shingle, railway embankments and limestone generally and is very common in Ireland.
There is a garden form 'Aureum'.
Roger Phillips in his book Wild Flowers of Britain claims that in Suffolk and Dorset this plant used to be known as 'Welcome home husband, though never so drunk.'
The flowers appear in June and July. Wall Pepper grows all over Europe, western Asia and North Africa. It is naturalised in North Am
