Stromanthe Triostar (Stromanthe sanguinea 'Triostar') is a dazzling prayer plant grown for its bold tricolour leaves splashed in green, cream and pink, with striking magenta-pink undersides revealed as the foliage lifts at night. A member of the Marantaceae family, it forms a bushy clump and brings vibrant tropical colour to bright, humid interiors. Native to Brazilian rainforests, it loves warmth, steady moisture and high humidity. Growing to roughly 60-90 cm indoors, it makes a showpiece for living rooms, offices and shaded balconies. It is non-toxic to pets and rewards consistent care with intensely coloured, ever-shifting foliage.
