What does wallpepper mean?
Wallpepper is a botanical name for a small succulent plant, most often identified as Sedum acre, a member of the stonecrop family. It has fleshy leaves and bright yellow, star-shaped flowers, and it is well suited to dry, rocky ground, crevices, and old walls. The name combines the plant's wall-dwelling habit with the pungent or pepper-like taste of its leaves, an association preserved in the alternative name wall pepper. In contemporary use, wallpepper is chiefly a horticultural and botanical term rather than a general name for an edible pepper or household spice. Gardeners may encounter it under scientific or alternative common names, including stonecrop and gold-bloom stonecrop, so its identification can depend on context. The word is useful because it distinguishes a particular low-growing plant from ordinary peppers and evokes the compact, resilient vegetation often found in rock gardens, dry borders, and masonry. Although uncommon in everyday speech, it belongs to the vocabulary of garden design, plant identification, and natural-history writing, where it names both a familiar garden subject and a characteristic feature of dry habitats.

Wallpepper earns its name twice: it grows on walls, and its succulent leaves have a pungent, pepper-like taste.
