Carpobrotus edulis (L.) L. Bolus
Mesembryanthemum edule L.
Ice Plant, Hottentot Fig, Highway Ice Plant, Pigface, Sour Fig
I couldn’t find an explanation for the common name, “ice plants.” It certainly isn’t related to their preferred climate, which is hot and dry. Ice plants are succulents—plants that cope with arid regions by storing water in thick leaves. Ice plants are native to South Africa. They were introduced into North America, where they thrived and are classified as invasive species in many habitats.
Identification: Plants form large, low-growing mats less than 5" (13 cm) high. Leaves are about 24-51" (60-130 cm) long, and triangular in cross-section, with each edge about ⅜-⁷/₁₆" (1-1.2 cm) long. Flowers are yellow or light pink and 2½-6" (6.3-15 cm) in diameter. Don’t confuse these with Carpobrotus chilensis:

Edibility: Fully ripe fruit can be made into pickles, chutney, etc. Leaves are edible, used in salads or as a substitute for pickled cucumber, though some don’t like the sticky nature of the interior (like okra).
