Senecio rowleyanus, commonly known as string-of-pearls or string-of-beads, is a creeping, perennial, succulent vine belonging to the family Asteraceae. This plant was named after British botanist Gordon Douglas Rowley who specialized in Cactaceae and succulents. It is native to the drier parts of southwest Africa. In its natural environment its stems trail on the ground, rooting where they touch and forming dense mats. It often avoids direct sunlight by growing in the shade of other plants and rocks.
