Like most Tradescantias it is easy to root. On T. pallidas I usually do it in soil. T. pallidas have stems that break off easily. Much easier than most Tradescantias. Some usually root just lying on the ground, even where they get foot traffic on them. Moving them in place for the summer, several pieces broke off. I stuck them in a catchall bed on the east side of the garage and haven't much attention to them. They are now growing pretty strongly. The red/purple color is affected by the amount of sunlight. I never have gotten the best color. All day sun and they get brownish or sort of a khaki color that's not attractive. Not enough and they tend to etoliate a bit and become more green. I think further out from the tree trunk would be better light for good color, but that space is taken.
