Often a stunning two-toned orchid of bright pink-red and white, this flower is a hybrid that can actually have various freckles and specks, and even other colors, such as orange. The Cattleya orchid are very fragrant, and they are very popular for use in corsages. They grow up to eight inches in width and come in a variety of colors and designs. The flower is also very popular among breeders and collectors, and they do well indoors.
This type of orchid has over 200 species and has a star-shaped appearance. Most of them have small- to medium-sized blooms and come in colors such as yellow, white, or light green, although most of them are white. The flower has a wonderful fragrance, needs even amounts of water, and prefers temperatures between 60 and 80 degrees Fahrenheit, mainly because they are not a bulb plant and therefore cannot store water. They also look beautiful in hanging baskets and pots.
Horticultural techniques have been devised for germinating orchid seeds on an artificial nutrient medium, eliminating the requirement of the fungus for germination and greatly aiding the propagation of ornamental orchids. The usual medium for the sowing of orchids in artificial conditions is agar agar gel combined with a carbohydrate energy source. The carbohydrate source can be combinations of discrete sugars or can be derived from other sources such as banana, pineapple, peach, or even tomato puree or coconut water. After the preparation of the agar agar medium, it is poured into test tubes or jars which are then autoclaved (or cooked in a pressure cooker) to sterilize the medium. After cooking, the medium begins to gel as it cools.
Most orchids are not heavy feeders. Many orchids bloom year after year with no fertilizer at all. During active growth, when new leaves are being produced, you may fertilize every other time you water at half the strength recommended on the fertilizer package. However, it's important to deliver water without fertilizer at least once a month to flush excess fertilizer salts from the bark mix and avoid fertilizer burn to the roots.
