Any tropical American plant belonging to the genus Anthurium, of the arum family, certain species of which are cultivated for their glossy red heart-shaped bract surrounding a rodlike spike of tiny yellow flowers. Anthurium is a genus of herbs often growing as epiphytes on other plants. Some are terrestrial. The leaves are often clustered and are variable in shape. The inflorescence bears small flowers which are perfect, containing male and female structures. The flowers are contained in dense spirals on the
spadix. The spadix is often elongated into a spike shape, but it can be globe-shaped or club-shaped. Beneath the spadix is the spathe, a type of bract. This is variable in shape, as well, but it is lance-shaped in many species. It may extend out flat or in a curve. Sometimes it covers the spadix like a hood. The fruits develop from the flowers on the spadix. They are juicy berries varying in color, usually containing two seeds.
The spadix and spathe are a main focus of Anthuirium breeders, who develop cultivars in bright colors and unique shapes. Anthurium scherzerianum and A. andraeanum, two of the most common taxa in cultivation, are the only species that grow bright red spathes. They have also been bred to produce spathes in many other colors and patterns.
Anthurium plants are poisonous due to calcium oxalate crystals. The sap is irritating to the skin and eyes. Anthurium can be propagated by seed or vegetatively by cuttings. In the commercial Anthurium trade, most propagation is via tissue culture
