Senecio rowleyanus
Medium · Some experienceAbout String-Of-Beads
Senecio rowleyanus, the string of pearls, is an instantly recognizable trailing succulent with slender stems strung with perfectly round, pea-sized green beads. Native to the arid regions of southwestern Africa, each 'pearl' is a modified leaf with a tiny translucent window that allows light to penetrate for photosynthesis while minimizing surface area to reduce water loss. The trailing stems can reach 60–90 cm, making stunning cascades from high shelves. Small white flowers with a cinnamon-like scent appear in favorable conditions. It is sensitive to overwatering.

History
Senecio rowleyanus is native to the dry rocky habitats of South Africa's Eastern Cape and parts of Namibia, where its nearly spherical pea-shaped leaves reduce water loss by presenting the smallest possible surface area to the sun — a remarkable example of xerophytic leaf geometry. It was named in 1968 after British succulent botanist Gordon Rowley. After decades as a minor curiosity it became a viral houseplant phenomenon in the 2010s as trailing container plantings moved from Instagram to mainstream retail.
Recent taxonomic work has moved it to the genus Curio as Curio rowleyanus, though Senecio remains dominant in the trade. It is moderately toxic to pets and can cause significant GI and neurological effects. String of pearls is named after Gordon Douglas Rowley (1921–2019), a British succulent expert who spent over 70 years studying and writing about succulent plants.
The spherical leaf shape is a masterpiece of evolutionary engineering — the sphere has the lowest surface-area-to-volume ratio of any shape, minimizing water loss while maximizing storage. The translucent 'window' stripe on each bead channels light to chloroplasts deep inside. This adaptation evolved independently in several unrelated desert plants. The plant became a social media phenomenon in the 2010s, driving prices up and inspiring jewelry and fabric designs.
