One of the succulent
Senecio, S. kleinia has articulated branches (constrictions that make them look like rows of sausages)
and thick, stubby, elongated leaves which rest directly on the main stem or branch without a petiole
Petiole (botany)
In botany, the petiole is the stalk attaching the leaf blade to the stem. The petiole usually has the same internal structure as the stem. Outgrowths appearing on each side of the petiole are called stipules. Leaves lacking a petiole are called sessile, or clasping when they partly surround the...

Horticulture

The plant is used in gardens with dry conditions. The plant requires a minimum exposure of the sun. The minimum winter temperature it can endure is -2 °C.

S. Kleinia has been successfully cultivated as a houseplant and as landscaping. It is on a list of suggested fire safe landscaping.
