Origin and Natural Habitat
Conophytum meyeri is a dwarf succulent endemic to the Richtersveld region of the Northern Cape in South Africa. It specifically inhabits the rocky, quartz-strewn hillsides in the region. In its natural environment, it grows in grit-filled crevices where it is frequently subjected to coastal fogs that provide moisture during the winter growing season.
Plant Characteristics
This species belongs to the “bilobum” group of Conophytum and is known for its small, heart-shaped or two-lobed bodies. The soft, fleshy leaves are typically a pale milky-green to glaucous-grey. Over time, it forms dense, attractive cushions of many individual heads. In autumn, it produces relatively large, bright yellow flowers that emerge from the fissure between the lobes, often completely obscuring the plant body.
Care Guide
Light
Conophytum meyeri requires bright, filtered light to maintain its compact shape and healthy colouration. While it enjoys direct morning sun, it must be protected from the intense heat of the afternoon sun, especially during the summer dormancy. A greenhouse with 40% shade cloth or a very bright windowsill with filtered light is an ideal location.
Soil
A very gritty, inorganic mineral soil is essential for the survival of this species. We recommend a mixture of pumice and akadama. The medium must be free-draining and should not contain any coco peat or heavy organic matter that could retain moisture around the base of the plant.
Water
Conophytum meyeri follows a strict seasonal cycle. Begin watering in late autumn when the new bodies begin to break through the old, dry sheaths. Water thoroughly, but infrequently, during the winter months. Allow the soil to dry out between each watering session. Stop watering completely in late spring as the plant begins to go dormant. During the summer, the leaves will shrivel and turn into a paper-like protective sheath. Do not water during this time, as any moisture will cause rot.
Pot size
Because of their small size and shallow root systems, these plants are best suited for small, shallow pots. An 8cm clay or plastic pot is usually more than enough for a cluster. Using a smaller pot also helps prevent the soil from staying wet for too long.
Temperature
This species is well-adapted to the cool, damp winters and hot, dry summers of the Northern Cape. It is happiest in temperatures between 10Β°C and 25Β°C during its growing season. It can tolerate light frost if kept bone dry, but it should generally be protected from freezing temperatures.
Humidity
Conophytum meyeri appreciates good air circulation and moderate humidity, mimicking the coastal fogs of the Richtersveld. However, it is very important to avoid stagnant, humid air, especially during the summer dormancy, as this can encourage fungal growth under the protective sheaths.
Fertilizing
Use a half-strength diluted liquid fertilizer once or twice during the peak growing season. Do not fertilize in summer.
Growing season
The active growing season is from autumn through early spring. This is when the plant flowers and produces its new bodies. Throughout the summer, the plant is strictly dormant.
Propagation
Conophytum meyeri can be propagated through seed or by division of older clumps.
Division: Cuttings or divisions should be taken in early autumn just as the plant is waking up. Ensure each head has a small portion of the woody stem attached. Let the plant callous for at least two weeks, then place the cutting in a gritty medium until new roots begin to form.
Seed germination: Sow seeds in autumn on the surface of a fine, sandy mineral mix. Keep the tray in a cool, bright spot and mist regularly with a fine spray. Germination usually occurs within one to two weeks. The tiny seedlings should be kept lightly moist. Do not let them dry out.
