Etymology
The specific epithet "graniforme" (pronounced gran-NY-form-ee) means "grain-shaped" and refers to the shape of the leaves of this species.
Origin
Rhinephyllum graniforme is native to South Africa. It grows on shaley flats between Laingsburg and Prince Albert in the Western Cape province.
Description
Rhinephyllum graniforme is a succulent shrublet with grain-shaped leaves densely packed along the branches. It can reach a height of 6 inches (15 cm). The leaves are gray-green and rough to the touch due to raised dots. They can grow up to 0.3 inches (1.7 cm) long. The old leaves remain dry on the branches for several years.
In the late winter and spring, Rhinephyllum graniforme produces solitary flowers with narrow, bright yellow petals. The flowers open in the late afternoon or early evening. The fruits are 5-locular capsules with broad valve wings and can reach a diameter of 0.3 inches (0.7 cm).
How to Grow and Care for Rhinephyllum graniforme
Light: Rhinephyllum graniforme requires bright light but not too much direct sunlight. So, a windowsill that receives 4 to 5 hours of direct sunlight in the morning and partial shade in the afternoon will be a perfect spot for indoor growing.
Soil: The plant thrives in porous soil, allowing the water to drain away quickly. Therefore, use commercial soil for succulents or make your own well-draining mix.
Temperature: High temperatures are not a problem as long as there is plenty of fresh air, but this plant is not cold-hardy. It grows best in USDA Plant Hardiness Zones 10a to 11b, with average minimum winter temperatures ranging from 30 to 50 °F (-1.1 to 10 °C).
Watering: To keep your Rhinephyllum graniforme healthy, it is most important to know when, how much, and how often to water it. During the dormant period, usually in summer, the plant requires little or no water. From fall to spring, water it thoroughly but allow the soil to dry between waterings.
Fertilizing: As long as you repot this plant every two years, it does not need fertilizer.
Repotting: Even if your plant can stay happy in the same pot for years, you can repot it once in a while to give it more space anytime during the growing season. However, the best time is at the beginning of the growing season.
Propagation: One simple way to propagate this plant is by stem cuttings during the growing season. Another option is to start it from seeds by sowing them in well-draining soil during the fall.
