Scientific Name
Conophytum cubicum Pavelka
Scientific Classification
Family: Aizoaceae
Subfamily: Ruschioideae
Tribe: Ruschieae
Genus: Conophytum
Origin
Conophytum cubicum is native to South Africa. It was discovered by Petr Pavelka at the end of the 20th century and is only known to occur on one quartzitic hill northeast of Eksteenfontein in the Northern Cape province.
Description
Conophytum cubicum is a spectacular dwarf succulent that forms a small clump of more or less cubic bodies with a concave upper surface. The bodies consist of a pair of leaves joined to their tips with only a small opening through which the flower stalk appears in mid-summer or early fall. They can grow up to 0.6 inches (1.5 cm) tall and 0.4 inches (1 cm) thick, tapering slightly toward their base. The epidermis is smooth, pale bluish-green to brownish, often red-spotted to red-crossed on the upper surface.
The diurnal flowers are white with a brownish-orange tube that can reach up to 2.4 inches (6 cm) in length. They are possibly the largest flowers in the genus.
Hardiness
USDA hardiness zones 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
Most Conophytums need bright light but do not like too much intense sunlight. To avoid sunburn, place them in a position to receive a few hours of full sun in cooler periods of the day.
These plants thrive best in a porous growing medium that will drain quickly. Use a commercial succulent soil mix specially designed for growing succulents, or make your own.
When Conophytums go dormant in the spring, they require little or no water. When plants begin growing in the fall, it is safe to water deeply, allowing the soil to dry before watering again.
Conophytums are light feeders and do not need fertilizer if repotted every two years. It is best to feed at the beginning of the growth period and just before flowering.
These succulents will benefit from repotting. Depending on the pot's size and growth rate, they typically need to be repotted every 2 to 4 years. The best time to repot a Conophytum is at the beginning of the growing season.
Conophytums are easily propagated by division. They can also be grown from seeds.
