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 25 cm (9.8 in) 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.
