Sleepy Granny is an Astrophytum myriostigma variegated. A variegated plant has sectors, patches, or stripes with two or more different colors, even distinct shades of green. Plants with variegated stems or leaves are often attractive and highly prized. In most species, the stems or leaves are normally green, and variegated epidermis is an uncommon mutation, termed a chimera. Chimeral variegation is due to losing the ability to produce chlorophyll in some of the plant’s tissue so that this tissue is no longer green. Tissues lacking chlorophyll are usually white or pale yellow colored (due to carotenoid pigments) or red (due to betalain or anthocyanin pigments) contrasting with the normal green tissue. There are several forms of variegation, depending on the tissues that have been affected. The variegation in some forms is unstable. The extent and nature of the variegation can vary, and sometimes the plant will return to the green form. In others, it is stable and does not change under normal conditions. Because the variegation is due to the presence of two kinds of plant tissue, propagating the plant must be by a vegetative method of propagation that preserves both types of tissue about each other.
