Huernia zebrina is a succulent suited to growing on a sunny protected porch.
This is one of the Stapeliad group of succulents, often known as the starfish flower group, which mainly come from Africa and Madagascar. Heurnia zebrina is commonly known as the lifesaver plant, due to the round disc on the flower looking like a Lifesaver ring. The plant makes a clump of compact angular stems up to 8 cm tall. Most Stapeliads are frost sensitive, and should not be watered much if at all in the colder months. They are also susceptible to mealy bug.
Apart from these challenges, most stapeliads grow well in the warmer months, and like to be watered regularly when growing. The very showy flowers of Stapeliads come in a range of shapes and colours, and may depend on pollination by flies - in which case the flowers may not have a nice smell. The genus Huernia usually does not have species with unpleasant smelling flowers.
