Anthurium andraeanum Tailflower, Flamingo Flower
Growing best in low-light conditions, Anthurium are handsome exotics with shiny dark green, oblong, heart-shaped leaves. The long-lasting, showy flower bracts come in shades of red, rose, pink, and white with a protruding pale yellow, tail-like flower spadix. The flower bracts have a puckered appearance and shine as though they were lacquered.
Anthurium will bloom more or less continuously, each plant having four to six flowers during the year. Each flower will last about six weeks on the plant or several weeks when cut and placed in a vase of water.

Use and Management
Soils should be moist and high in organic matter, and relative humidity should remain high. Anthurium leaves lose their shiny texture and may die if humidity drops below 50% for more than a few days. For interior use, keep potted plants on trays of moist gravel or spray several times per day with water and protect from drafts. Single plants are best used in small gardens. In larger landscapes, a mass of many plants together looks best.
Plant two to three feet apart to form a dense foliage effect.
Propagation is by division.
The shiny, deep green leaves and lush leafy form of Anthurium will give the landscape a cool tropical feel. The mass of smooth, heart-shaped leaves highlights the bright, showy flowers. Pair with plants that are softer with small foliage and low-growing mounding or spreading forms, or with other large-leaf tropicals with irregular, coarse texture such as philodendrons. Yellow-green or variegated green foliage in the companion plants will highlight the deep green of the leaves. When pairing with other flowering plants use white and bright yellows to contrast the deep green and highlight the warm reds of the flower bracts and the yellow spadix.
Pest and Diseases
No diseases are of major concern.
Mites, scales, mealy-bugs, and nematodes can be a problem.
