The genus Vriesea is known primarily for spectacular inflorescences among its 250 species. Although it is very closely related to Tillandsia, the plants are usually very different. Most vrieseas are tank bromeliads with soft, shiny (nearly scaleless), yellow-green to dark green leaves. Many have foliage that is red or strikingly marked with intricate patterns of bands or translucent windows.
The mostly sword-shaped (strongly flattened) flowering spikes vary from single to many-branched. The bracts are usually colored brilliant red or yellow and last several months. Bicolored and multicolored spikes are common. Many hybrids have been produced; these cultivars are vastly superior in color and ease of culture to most of the wild species. Just as some tillandsias are green, tank-forming plants, some vrieseas are gray-leafed, atmospheric epiphytes. Give these gray species tillandsia culture. The instructions in this section are for the soft-leafed, tank vrieseas. LIGHT. Vrieseas adapt to a wide range of light conditions from fairly deep shade (guzmania conditions) to nearly full sunlight (neoregelia conditions), a range of 1500 to 8000 footcandles. At higher intensities plants require high humidity to prevent burning. The best growth is obtained between 2000 and 5000 footcandles. In sunny climates 60% to 70% shade cloth is recommended. TEMPERATURE. Vrieseas adapt to a wide range of temperatures. Mid90soF/ mid-30soC are tolerated with good air circulation, but hot, stuffy conditions will quickly damage the plants. Hot nights adversely affect foliage and inflorescence color. Brazilian species and hybrids will tolerate near or slightly below freezing; Central American and Andean types will not tolerate cold. AIR. Follow basic culture. WATERING. Follow basic culture. POTTING AND MOUNTING. Follow basic culture. Small pots are especially important for this group. Vrieseas are not recommended for mounting except in very humid growing conditions. Moss is not necessary. FEEDING. Follow basic culture. Vrieseas adapt to strong or weak fertilizing. PROPAGATION. Follow basic culture.
