This plant, cryptanthus bivittatus "ruby" is a great, somewhat different bromiliad because of its flattened growing habit and wonderful coloration of the leaves. Unlike many bromiliads, its primary "show" is the foliage rather than the blooms. When I purchased it from Westwood Gardens in Fayetteville, AR, it had its characteristic, wonderful, red foliage, but after a few gloomy weeks indoors, it lost this coloration and became an attractive green, yet this was not the coloration for which I purchased it.

They grow best when the soil is allowed to dry out slightly, then totally soaked. They also grow well when the soil is kept evenly moist but not damp. Though Cryptanthus are considered low light or light shade plants, many actually only begin to display their beautiful foliage colors when exposed to more intense ligh... read more

Flowers are small and white, appear near the center. Small pups develop between the leaves; when they are 1/3 the size of the parent, detach them (they should come away with a gentle tug) and repot them. Another variety often seen is
Cryptanthus "Starlite".
