Aganisia cyanea (formerly Acacallis cyanea) is a showy species of orchid native to Colombia, Venezuela, Peru and Brazil and widely cultivated elsewhere as an ornamental. [1] It is remarkable because some cultivars of this species produce blue flowers, the color blue being quite rare among the orchids. They are considered difficult to maintain in cultivation without a controlled growing environment. [2]

Biology

Aganisia cyanea is found in very wet, lowland rain forests in northern South America growing on lower sections of the trunks of large trees. The plants can be submerged under water during monsoons for several weeks due to flooding in habitat with no apparent harm. [2] [3]

The plants grow from a creeping rhizome with inter-spaced pseudobulbs with one apical, usually pleated leaf. These plants bloom from the base of the pseudobulbs, and produce a raceme of up to 10 flowers.

The flowers of these plants have a metallic, almost surreal appearance and appear to be made of bluish metal. This is very striking. The flowers take on a more bluish cast when not exposed to direct sunlight. [2] [3]

Cultivation

In cultivation, they are best accommodated on tree fern or cork bark slabs mounted bare root and given high humidity and abundant water and feeding year round, and moderate shade. They prefer moderate to warm temperatures.

The species is much sought after in cultivation because of its blue metallic flowers. These plants are protected under CITES II and local and regional laws and should not be removed or disturbed in habitat.

The plants are available commercially from flasked seedlings of varieties that are amenable to cultivation and these plants are easily obtainable. [2] [3]

Orchids are plants that belong to the family Orchidaceae, a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is found in the tropics.

<i>Bulbophyllum</i> Genus of orchids

Bulbophyllum is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is the largest genus in the orchid family and one of the largest genera of flowering plants with more than 2,000 species, exceeded in number only by Astragalus. These orchids are found in diverse habitats throughout most of the warmer parts of the world including Africa, southern Asia, Latin America, the West Indies, and various islands in the Indian and Pacific Oceans. Orchids in this genus have thread-like or fibrous roots that creep over the surface of trees or rocks or hang from branches. The stem is divided into a rhizome and a pseudobulb, a feature that distinguished this genus from Dendrobium. There is usually only a single leaf at the top of the pseudobulb and from one to many flowers are arranged along an unbranched flowering stem that arises from the base of the pseudobulb. Several attempts have been made to separate Bulbophyllum into smaller genera, but most have not been accepted by the World Checklist of Selected Plant Families.

<i>Vanda</i> Genus of orchids

Vanda, abbreviated in the horticultural trade as V., is a genus in the orchid family, Orchidaceae. There are 90 species, and the genus is commonly cultivated for the marketplace. This genus and its allies are considered to be among the most specifically adapted of all orchids within the Orchidaceae. The genus is highly prized in horticulture for its showy, fragrant, long-lasting, and intensely colorful flowers. Vanda species are widespread across East Asia, Southeast Asia, and New Guinea, with a few species extending into Queensland and some of the islands of the western Pacific.

<i>Laelia</i> Genus of orchids
