One of the few zebrinas that do not have silver stripes. It is green in a dark place and purple stripes appear in a sunny place (it looks a bit like 'Tikal').
Below is a comparison of two cultivars called 'Purple Plush': Tradescantia zebrina var. mollipila 'Purple Plush' (left) and Gibasis geniculata 'Purple Plush' (right).
