Stapelia paniculata var. scitula Family: Apocynaceae (Asclepidaceae). An attractive Stapeliad fuzzy upright stems. Flowers are dark red with many bumps and folds. Flowers are most common and numerous in the late summer and fall but can bloom any time of year if happy. They can take some direct sun, but aren't full sun plants. These flowers have no strong scent, so you don't have to worry about it stinking up your house (lots of Stapeliads smell like rotting meat).
Give lots of light, but protect from hot afternoon sun in summer. During the growing season they can be watered as much as any other succulent (i.e. regularly but don't let the soil stay wet). Keep drier in the winter. Cool and wet or low light and wet are what rot this and all other Stapeliads.
