Description of Hippeastrum, Amaryllis
Family Amaryllidaceae – Amaryllids
The native name ” Hippeastrum” was created by the combination of the Greek words hippeos meaning knight rider, horse and star. there are more than 80 original parental species.. Hippeastrum has been so thoroughly cultivated after years of hybridization with related species that today’s hybrids grown under the generic name ” Hippeastrums. are very different from their parent wild type of bulbs, leaves and especially huge bell shaped flowers that are wide open and in pure colors( red, pink, white, yellow or colored in color). Today there are a large number of hybrids and cultivars that can no longer be traced and they are lost in history.. An estimate of their number is about 600. Around 20-25 new varieties presented for sale every year and 10-15 are canceled each year. New and exotic are sold with the greatest interest and the fastest sale ratio.
Hippeastrum species comes from the mountains of savanna and forests of subtropical America (Argentina, Peru, Brazil, Mexico) and from Africa. Formerly its scientific name was ” Hippeastrum amaryllis “. At present, however, Amaryllis refers to a plant originating from South Africa. They are mutually interchangeable. The true amaryllis is ” Amaryllis belladonna “it is the plant which grows best in the outdoor environment.
The largest bulbs can measure upto 14 to 16 inches (36 to 41 cm) in circumference and can produce three or more scapes (flower stems) with four or more blooms each. flowering depends on bulb size.The common available bulbs measure 10 to 12 inches (28 to 34 cm) which can produce two scapes having four to six flowers on each stem which depends on the cultivar. Some healthy bulbs can send two flower scapes (flower stems) at the same time while many other wait several weeks between blooms and sometimes the second scape decreases flower power and will produce only two to three flowers rather than the usual four. hollow flower bud(flower stems) can reach a height of 30cm to 100cm. The amaryllis usually breeds from february to May. On the bulb, at least four large, healthy leaves must grow during the vegetation so that one or two flower buds can be grown in the following year. Sometimes leaves and buds grow up both at the same time or within a few weeks. The most common number of flowers per mature bulb is from two to four but occasionally six or seven as in neon amaryllis. Dry bulbs can be purchased from autumn to April. The bigger the bulbs, the more flower stalks they can have. There are 5 basic types of amaryllis /hippeastrum:
single, double, small, cybister, trumpet.
The largest flower bulbs are produced in the Netherlands with South African sources. Currently, new varieties are grown in the United States, South Africa, Israel, India, Brazil, Australia, and double blooms in Japan.
Original parent species of Hippeastrum
Hippeastrum canterai Arechav.
The entire parts of plant are poisonous for both humans and animals. It contains toxic alkaloids mostly in bulbs. After consumption, headaches, vomiting, malaise, and abdominal pain can occur.
