This small-leaf plant tends to look creamy and light at first. But then its ruddy stems become visible, and the reason for its name becomes evident. With lavender-pink blooms appearing on the tips of stems in spring, this plant’s creamy leaves are only the start of how this plant adds color to an indoor display. Portulacaria afra rainbow bush likes warmth, so be sure to position it in a draft-free location. While Portulacaria afra rainbow bush grows as a fairly sizable shrub in the right climates, it can be kept petite when grown in containers. And its pale green leaves with creamy margins will offset the colors of other plants you have in your collection.
