Senecio rowleyanus is a creeping evergreen perennial succulent with cascading stems of large, round, bead like leaves. Its trailing stems can reach 60-90cm (2-3 feet). There is a small point at the tips of the spherical leaves and a window on the side. This window allows the light to enter the leaf for photosynthesis but protects the cells from extreme heat. The leaf sphere shape allows the most water storage and reduce the surface area exposed to the hot sun and dry air, thus minimizing the loss of precious water through evaporation.It bears white daisy like flowers during the summer. The flowers are clusters of small 1cm (0.4 inch), white trumpet-shaped flowers studded with colorful stamens. A compound flower which looks like a cluster of tiny white lilies with long anthers sticking out the center of each flower. The small white flower is not showy but fragrant. The bloom will last about a month. The flower is followed by seed. The seeds have cottony filaments attached probably to aid the spread with winds. It pops open like a dandelion.
