One of my favorite types of desert plants are the African Conophytums. Those in my collection have just begun to grow and bloom this year, so I've watered them for the first time since around April. In the winter they do their growing in areas that get a bit of winter rain, and in the summer their two leaves die, leaving a sheath that looks so much like normal ground that they are protected from both the hot sun and herbivores. Then when the weather starts to cool, and the first rain falls, they break out of their own mummies, often with a delicate flower of yellow, white or red:
and during the growing season have all sorts of nice shapes, colors and markings. Not the easiest plants to grow; they can't have any water during the summer or they rot, they burn if an unexpected hot day comes, the grow really slowly. But they can be very rewarding given the diversity of color and shape.
