The charming, somewhat odd looking String-of-pearls calls South Western Africa its home. There, it grows in a strictly limited geographical region in the Eastern and Western Cape provinces. It often thrives there in the shade of bushes or mountains which provide some protection from the strong sun. Senecio rowleyanus belong so the daisy (Asteraceae) family. The Senecio genus has more than 1,000 species, which include annual and perennial shrubs and woods, as well as some succulents, such as string of pearls.

They are a popular cultivated as an ornamental foliage plant in baskets thanks to their spectacular appearance, the ‘pearl strings’ can easily grow to 3 feet long.

String-of-pearls leaves

The leaves of the Senecio rowleyanus are lined up like little ‘pearls on a string’.

They certainly have a novel shape: Several green-white bracts sit directly under the flower head. The bracts grow to three quarters of their length and have a violet margin.
