Lithops bromfieldii var. mennellii (L.Bolus) B.Fearn
Accepted Scientific Name
Lithops bromfieldii L.Bolus
This succulent is native to South Africa (a small area south of Upington near Orange River in the Northern Cape). It is not accepted as a variety, and it is treated as a form of Lithops bromfieldii.
Lithops bromfieldii var. mennellii is a dwarf succulent with bodies that consist of two thick, fleshy leaves fused in the shape of an inverted cone, with a central fissure dividing them. The bodies grow up to 0.6 inches (1.5 cm) tall, solitary or usually in clumps of 2 to 10. The upper surface of the bodes is flat or slightly convex, elliptical to kidney-shaped, up to 1.4 inches (3.5 cm) long, and up to 0.8 inches (2 cm) wide. They are beige to pinkish-gray with impressed, branched, dark brown lines on the upper surface. Flowers are yellow, up to 1.2 inches (3 cm) in diameter, and appear from the fissure between the leaves in fall.
The varietal epithet "mennellii (men-NEL-ee-eye)" honors Brian T. Mennell, who collected this plant in April 1934.
How to Grow and Care for Lithops bromfieldii var. mennellii
Light: A sunny windowsill where the plant receives 4 to 5 hours of direct sunlight during the early part of the day and partial shade during the afternoon is the perfect spot to grow your L. bromfieldii var. mennellii. You may place the pot on the balcony or in the garden from spring to fall.
Soil: L. bromfieldii var. mennellii thrives best in a growing medium that will drain quickly. Use a commercial soil mix for succulents, or make your own.
Temperature: High temperatures are not a problem for this plant as long as there is plenty of fresh air, but it is not a cold-hardy succulent. L. bromfieldii var. mennellii can withstand temperatures as low as 30 °F (-1.1 °C). USDA Plant Hardiness Zones 10a to 11b, 30 to 50 °F (-1.1 to 10 °C).
Watering: Like all Lithops, this succulent has a specific yearly cycle of growth, and it is important to water only during certain stages, but it is also important to keep the soil dry at other stages of its growth. How often you need to water your L. bromfieldii var. mennellii depends on how quickly the potting mix dries out. It is essential to let the soil dry out between waterings. Stop watering during the winter to allow the old leaf pair to dry out and the new pair to develop.
Fertilizing: L. bromfieldii var. mennellii does not need to be fertilized. It will thrive without any feeding. If you decide to feed, use a fertilizer with high potassium and low nitrogen levels.
Repotting: This small succulent will happily stay in the same pot for several decades. The common reason for repotting is dividing the plant or allowing space for clusters to grow. Repot only when its growing season starts.
Propagation: L. bromfieldii var. mennellii is most often grown from seeds. However, if you have a multi-headed plant, it can also be propagated by division. Sow the seeds during the summer.
