Description
Lithops pseudotruncatella subsp. volkii is a dwarf succulent with bodies that consist of two pale bluish-white leaves veined and mottled with olive-brown on the tips. It can either grow solitary or from a small clump. The bodies can grow up to 2 inches (4 cm) tall, while the upper surface can reach up to 2 inches (5 cm) in length and 1.4 inches (3.5 cm) in width.
The flowers are yellow, occasionally white, and appear from late summer to fall, reaching up to 2 inches (5 cm) in diameter.
Hardiness
USDA hardiness zone 10a to 11b: from 30 °F (−1.1 °C) to 50 °F (+10 °C).
How to Grow and Care
These plants develop a new set of leaves every year, with new leaves emerging in the fall and growing through the winter and into the summer. Lithops will go dormant in late summer, and water should be severely restricted to prevent bursting leaves. The flowers appear near the end of summer or fall, first showing up as a small bud forcing its way between the leaves, and growth will begin again. It's safe to water during this period. Heading into the winter, the leaves will still grow, but you should stop watering, even as the older leaves shrivel and encase the new growth. In the spring, it's safe to begin lightly watering again as the plant begins to grow again, heading toward its summer dormancy period and the emergence of new leaves in the fall.
Lithops are very slow-growing, small plants, making them ideal as houseplants (once you get the hang of their watering schedule). Older plants form attractive clumps of "pebbles" in their pots, which are highly prized. In general, plants should only be repotted if there are cultural problems (soggy soil) or the plant has outgrown its dish container, which will only happen every several years.
