People garden for lots of reasons and one is to experiment with unusual - okay, weird - varieties. If oddities float your boat you'll like Lithops, commonly known as Living Stones. These peculiar plants were first discovered in South Africa in the early 1800's by W. J. Birchell, an African explorer who was fascinated by the rock formations at his feet only to discover that the pebbles were actually plants. These succulents require next to no care and grow slowly so you won't find yourself having to trim and fuss. Plant them in the sun, in well drained soil that receives scant moisture and let them masquerade as paired half moon shaped stones (which they do in wild setting to avoid being eaten.) Or park them on a sunny windowsill and watch friends' reactions. (Hint - regardless of their age they'll want to touch the "stones".) Just to keep you guessing, lithops produce cactus-like flowers when you least expect. In their native lands Living Stones thrive in areas that receive 2" of rain a year (no, that's not a typo) so if you provide a tablespoon of water every two months, these plants will be happy. We'll send a 5.5" pot with a grouping of plants, each of which consists of two semi-circular "leaves" in peach, tan and gray with mottled markings.
