Stromanthe Sanguinea (S)While some plant families harbour thousands of family members, others are relatively small. The Stromanthe tropical house plant family is of the latter kind and consists of roughly ten different varieties, of which the Stromanthe Sanguinea is one. Close relatives of prayer plants, Stromanthe plants are native to South America and do well in partial shade or indirect light. They do not tolerate sunlight so stay away from south facing windows.
