Anthurium crystallinum
This crystal anthurium is a foliage species prized for large, velvety leaves with bright silver veins. It stands out where dramatic, reflective venation is desired. Small green spathes may appear but the foliage is the feature. It performs best with bright, indirect light, warm temperatures, and humid air. In North America it is typically grown indoors or under glass.
