This genus belongs to the large bromellad family (Bromeliaceae) and consists of around 65 species of evergreen perennials and about 500 cultivars. Most species are epiphytic or rock dwelling and come from Mexico and the warmer regions of Central and South America. The leaves form a tubular rosette and range in color from dull olive green to gray-green with a variety of attractive markings. Showy stalked flower clusters emerge from the leaft rosttes. The flower are globular to cylindrical and have side spikes of blue-green to navy blue petals. Bright pink or red banner-like bracts appear underneath the flowerhead. Billbergia plants are commonly referred to as vase plants because the central hollow of the plant acts as an important storage area for water between rainfalls.
CULTIVATION
Most plants in this genus are easy to grow and are suitable for both indoor and outdoor planting. If planting outside, keep the plant in a sheltered humid spot in a porous fast-draining soil mix or a mound of stones. Use the shoots that grow from the base of the plant for propagation.
Top Tip
If grown as indoor plants, Billbergia species need to be potted in a mixture composed of leaf mold, bark, and sand. They do best if placed in a warm sunny position.
