In the wild, P. emarginata is usually found on mossy rocks where water constantly flowers year round. This species has small rosettes with curled leaves, and the center of the plants turn a nice reddish color. The flowers are jagged and among the most variable. I've seen white, blue, purple, and pink flowers of varying sizes and shapes. It flowers frequently during th cooler months. I keep this species wetter than normal pings, and have a higher amount of peat in the mix, as it seems much more suspecitble to drying out compared to most other Mexican species.
