Houseplant, String of Bananas Plant

Botanical name: Senecio radicans
Synonmy: Curio radicans
Family: Asteraceae

String of Bananas Plant also called String of Fishhooks is a unique houseplant which bears pendant thread-like stems on which are tiny leaves shaped like small green bananas. String of Bananas is a creeping, perennial, succulent vine native to the drier parts of Southwest Africa. In its natural habitat, it grows as a trailer, with stems trailing on the ground, rooting where they touch and forming dense mats. It prefers the shaded conditions growing under other plants and rocks. The odd shaped leaves is an adaptation to arid conditions and allows for the storage of water while exposing minimum surface area to the dry desert air which greatly reduces water loss. The fleshy leaves and stems store water, which allows the plant to go for a considerably long period without being watered. Each leaf bears a translucent window that runs the length of the leaf which allows light to reach into interior of the leaf where photosynthesis takes place.

String of Bananas Plant is closely related to Senecio hallianus, which is very similar to String of Bananas but its foliage is blue-green; Senecio rowleyanus (String of Pearls), whose leaves are spherical; Senecio herreanus (String of Beads), whose foliage is oval-shaped; Senecio peregrinus (String of Dolphins), whose foliage looks like jumping Dolphins and Senecio citriformis (String of Tears), whose foliage is lemon-shaped. The cascading thread-like stems and the odd-shaped foliage make these plants perfect for a hanging basket, table top or a shelf.
