Curio rowleyanus, formerly known as Senecio rowleyanus, is a very popular succulent with trailing stems lined with small pea-shaped leaves. The stems root at the nodes and grow up to 3 feet (90 cm) long. Leaves are almost spherical, about 0.3 inches (0.8 cm) in diameter, with a small pointed tip and a longitudinal translucent stripe. Brush-like clusters of small white to nearly white flowers with long red stamens and bright yellow anthers appear in summer on up to 1.5 inches (3.8 cm) long peduncles. They have the aroma of cinnamon.

The specific epithet "rowleyanus" honors Gordon Douglas Rowley (1921–2019), a British botanist and writer specializing in cacti and succulents.

Fertilizing: The members of this genus can take a bit more fertilizer than other succulents if you want them to grow fast.

Repotting: You do not need to repot Curio plants often. You can do it when you see that the container becomes too small or shallow.
