Senecio rowleyanus has small spherical leaves about 1/4 inch in diameter. These are strung on thin stems like beads of a necklace. These stems also carry adventitious roots which grow down into the soil as the stems lengthen so that eventually the plant becomes a dense mat on top of the soil as well as the lengthening stems hanging over the edge of the pot at they grow longer. Small flowers are white and smell like cinnamon. Senecios must have bright light including two to three hours a day of direct sunlight through the year.
