LithopsLithops are an amazing plant - yes, I said plant. I know, they don't look like one! They are called living stones for a good reason. They look just like a couple of pebbles, and this camouflage prevents hungry, thirsty animals in their native South Africa and Namibia from gobbling them up during a drought.
They have several other interesting survival strategies; one they use during a prolonged drought is to burrow down into the soil leaving just a tiny portion of their special window showing. This window is a clear area on the top of the truncated or shortened leaf through which they allow light in to be photosynthesized. They also have a long taproot to enable them to reach any moisture lower down in the soil layer. In cultivation, they’ve been known to live for over fifty years. There are many different colourations in Lithops. They range in colour from almost white, grey, pink, purple, beige or smoky green. They have varying patterns to enable them to more closely resemble a small stone. This, and the fact that they’re so slow growing, makes for a fascinating hobby – you can collect from among over two hundred differing types and species. Because of their small size, you can fit a lot of Lithops in a small space. BloomingAn amazing thing happens when Lithops bloom. A flower will emerge from between the two fat little leaves, and gradually over the span of a few days, open into a large white or yellow daisy like bloom. This is usually in autumn or winter and is dependent on the amount of light a plant receives in the spring and summer. A three year old plant will commence blooming with these slightly spice scented flowers.CareLithops are not a hardy succulent plant – they cannot stand any temperatures lower than 4 degrees Celsius, but can withstand a lot of heat, a legacy from their native habitat. They must have a dry dormant period in winter and early spring, until they completely rebuild their body. During this time they should be kept cool, but not allowed to freeze. Then the old shriveled parts can be removed, and you can water again.
Watering - Especially Important!When watering, the soil must be thoroughly soaked through, then allowed to dry almost completely. In late spring or early summer, they must be allowed a dry dormant period again to rest, after which they will begin growing. This dormant period is important for the health of the plant, so make sure they won’t accidentally get watered with other summer growing plants in your collection. They also need good ventilation at all times.LightLight should be bright, but avoid full sun in a south facing window as it can burn the plants.SoilPreferred soil is very well drained, either a cactus mix specifically blended for cactus, or something like Sunshine Mix #4, which has added aggregate. It’s good to add even more grit to the mix for additional drainage. Lithops don’t need any fertilizer, so don’t worry about the addition of nutrients. They really do prefer a lean soil.Look for Lithops here in 2011 as I’ll have some for sale then.
