Lithops optica 'Rubra'
Lithops optica 'Rubra' is almost identical to Lithops optica, but the body is milky pink to reddish-purple with light to dark ruby-red, windowed tops. It is a succulent with obconical, almost club-shaped pair of opposite leaves up to 1 inch (2.5 cm) in diameter. The stem is very short and not visible. Each leaf pair will produce one solitary, bright, daisy-like flower, white in color, sometimes with pink tips and up to 1 inch (2.5 cm) in diameter.
USDA hardiness zones 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. In late summer, Lithops will go dormant 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 be growing, but you should stop watering, even as the older leaves shrivel up 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 their summer dormancy period and the emergence of new leaves in the fall.
Lithops are very slow growing, small plants, which makes 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… – See more at: How to Grow and Care for Lithops
