Remember I said I found two variegated Commelina communis this spring? Well, I have spent the summer propogating it into two large clumps. I will post a pic of it when I get home tonight. Several people on the Name That Plant! forum were convinced I had an escaped houseplant (a form of Tradescantia) on my hands, and that it would bloom white. Well, this is not that. It blooms a lovely blue every morning, just like regular Commelina! Here's a tidbit of plant knowledge for you regarding the type of variegation that my plant likely has... it's kind of like my plant is a mixture of an albino plant (which can't survive in the wild) and a regular one. I noticed that this plant seems a little more "spidery" than regular Commelina, and grows slower. That fits, based on the info below.

Chimeral variegation

Plants bearing such variegation are chimeras, with more than one type of genetic makeup in their tissues. A lack of chlorophyll producing tissue in some tissues causes variegation with white or yellow coloured zones on the leaf, contrasting with the usual green tissue. It is due to some of the plantÂs meristematic tissue losing the ability to produce chloroplasts, so that the tissue it produces is no longer green.

There are several types of such 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 in relation to each other.

As these plants have some of their tissue unable to carry out photosynthesis, the plant will be weaker than the plain green plant. They should generally be expected to die out in nature.
