One of the most popular plants with maroon leaves is the Red Maranta or 'Prayer Plant'. This plant is native to Brazil, and it features striking foliage that can bring a unique look to any home. The top side of its leaves are deep purple-maroon in color, while their underside is light green. It grows slowly so you don't have to worry about pruning it too often. With adequate care, the Red Maranta will reward you with an abundance of vibrant foliage for years to come! When grown indoors, this plant needs bright indirect light and high humidity levels in order for its full potential of dark maroon shades to be achieved. To provide adequate moisture on those hot days during summertime, misting your Prayer Plant's leaves will help promote better air circulation around them too!
