Stromanthe Triostar
Stromanthe sanguinea
Stromanthe triostar (Stromanthe sanguinea 'Triostar') is a bold, variegated tropical plant with striking, painted foliage — each leaf displays a blend of green, creamy white, and hot pink, while the undersides glow magenta. It’s part of the prayer plant family (Marantaceae), which means it exhibits nyctinasty — folding its leaves upward at night.
Native to the rainforests of Brazil, this plant thrives in bright, indirect light, high humidity, and consistently moist soil. It’s perfect for plant lovers looking to add a pop of color, but it does best in homes where humidity can be boosted or maintained.
