Inch Worm is a plant with succulent stem , from the Arabian peninsula and northeastern Africa. It is a cactus-like plant, but interestingly, belongs to the sunflower family. It is so named because of the growth habit of its rounded, segmented stems that grow out of the soil, then curve downward into the soil then back out again and continue along the ground surface, rooting at internodes. Flowers are bright orange-red in color.
