Conophytum burgeri L.Bolus. Br.
Burger's Onion, Little Light Bulbs
Conophytum burgeri is a dwarf succulent with two fleshy leaves fussed in an onion-shaped body with a tiny fissure at the top. It slowly grows up to 1.2 inches (3 cm) tall and up to 1 inch (2.5 cm) in diameter, solitary or gradually subdividing to form a small clump of up to 5 bodies with age. The body is smooth, shiny, and translucent, varying in color from light green to purple.
The flowers are purple and appear in early fall, opening briefly in the mid-afternoon.
Conophytum burgeri is native to South Africa. However, it is restricted to the mines of the Aggeneys valley in Northern Cape Province, occurring at a single, small subpopulation numbering fewer than 250 plants.
USDA hardiness zones 10b to 11b: from 35 °F (+1.7 °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 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 they are 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. They typically need to be repotted every 2 to 4 years, depending on the pot's size and growth rate. The best time to repot a Conophytum is at the beginning of the period of active growth.
Conophytums are easily propagated by division. They can also be grown from seeds.
