Anthurium Cultivation@@@@@@ Anthurium is an evergreen, tropical herbaceous plant cultivated for its colourful spathe and unusual attractive foliage. Among the number of species available, the most popular and economically important species are Anthurium andreanum and A. Scherzerianum, which posses’ attractive longlasting inflorescence. The Anthurium belongs to family Araceae. Derives its name from Greek language ‘Anthos’ means ‘flower’ and ‘Oura’ means ‘tail’ indicating the flower with a tail. The attractive colourful plant that is traded is actually a modification of the leaf, which is botanically called ‘spathe’.  The heart shaped spathe appears on a long flower stalk and a number of veins that originate from the junction of the spathe and the flower stalk. The veins are interconnected with secondary and tertiary veins.  A cylindrical fleshy ‘spadix’ originates from the same junction and produces a number of bisexual flowers (150-250 flowers) which are arranged in concentric whorls.  The female part of the flower matures first (protogynous), which can be noticed by nectar like secretions in the form of shining droplets on the flowers. The genus Anthurium can be categorized into two distinct groups – o Flowering types and o Foliage types. Although some Anthurium species flowers are inconspicuous and unattractive, they have unique velvety attractive foliage. Such Anthurium is grown as foliage potted plants. The flowering group products remarkably attractive spathe and colourful spadices, but the foliage may not be so attractive. VARIETIES The present day flowering Anthuriums are mostly hybrids of A. andreanum and A. scherzerianum. Some of the hybrids/varieties evolved during early stages of varietals improvement are listed below.

TYPES OF ANTHURIUM There are three basic types of Anthurium flowers 1. STANDARD: They have the most common heart shape, the spathe lobes often overlap. Sizes range from 12x11cm to 20x18cm. Colour range includes red, orange, pink, Coral, white and green. 2. OBAKE: Popular for their two-tone coloration usually a bi-colour pattern of green and a major spathe colour. Some varieties will lose their green colour in summer resulting in solid coloured spathe. Sizes vary from 8x7cm miniatures 28x23cm large varieties. 3. TULIP: They have up right cupped spathes, with a straight and erect spadix. The spathe size ranges from 10x6cm. Tulip types are mostly hybrids with more than one species as their parents. DIURNAL TEMPERATURE For a luxuriant growth the cultivated Anthurium (A. andreanum and A. scherzerianum) required 18.3oC during night whereas A higher night temperature of 21.2 to 23.9 oC is essential for initiation of flowering. Anthurium cannot tolerate freezing temperature. At the same time Anthuriums do not prefer temperatures above 35 oC. If the temperature exceeds 35 degree centigrade coupled with low relative humidity leaf scorching is common.
