''Umbilicus rupestris'' (Navelwort, Penny-pies, Wall Pennywort) is a fleshy, perennial, edible flowering plant in the stonecrop family Crassulaceae (in the genus ''Umbilicus'') so named for its umbilicate (navel-like) leaves. Wall pennywort grows to an average of high. The pallid spikes of bell-shaped, greenish-pink flowers of this plant first appear in May, and the green fruits ripen through the summer. Both the name "navelwort" and the scientific name ''Umbilicus'' come from the round shape of the leaves, which have a navel-like depression in the center. == Distribution == The plant is found in southern and western Europe, often growing on shady walls or in damp rock crevices that are sparse in other plant growth (thus, "wall" pennywort), where its succulent leaves develop in rosettes. It is not at present under threat.〔Lockton, A.J. (2009-12-05). ("Umbilicus rupestris" ). BSBI Species accounts.
