[28][96] One alkaloid isolated from Hippeastrum vittatum (montanine) has demonstrated antidepressant, anticonvulsant and anxiolytic properties. 'Large Flowering', 'Dutch', 'Royal Dutch', there are five types that are commonly sold; 'Trumpets', as the name suggests, have flared, tube-shaped flowers. [b][41] Linnaeus had earlier worked on the Estate of George Clifford near Haarlem between 1735 and 1737 describing the plants growing there in his Hortus Cliffortianus in 1738. [64], Species are generally diploid with 2n=22 chromosomes, but some species, such as Hippeastrum iguazuanum, have 24. [74] The leaves are also eaten by grasshoppers, and grasshoppers commonly plant egg pods in the ground near Hippeastrum bulbs, which erupt in the spring, covering the plant with nymphs. The androecium consists of six stamens with filiform (thread like) filaments, which are fasciculate (in close bundles) and declinate or ascendent. [43] This was assumed to be the South African Cape Belladonna, although not precisely known. In 1819 Herbert had proposed Leopoldia as a nomen provisorium (provisional name)[13] for the same taxon as he called Hippeastrum in 1821. Each flower is 13–20 cm (5"–8") across, and the native species are usually purple or red. Phonetic Spelling hip-ee-AY-strum This plant has medium severity poison characteristics. The most conspicuous exception is the hybrid obtained through crossbreeding with the Mexican Sprekelia formosissima Herb. [26] In the gynaecium, the ovary is inferior and trilocular with pluriovulate locules. However, the genus Amaryllis still exists today. William Herbert in Curtis's Botanical Magazine[44] which he expanded in 1821 in The Botanical Register, identifying 14 species of the new genus of Hippeastrum, and only leaving three species in Amaryllis. Three main methods are used for propagating Hippeastrum: seeds, bulbils and 'twin scales'. In temperate climes these can be placed outside in the summer, and after a dormancy period, be induced to rebloom inside in the winter. Because they thrive in U.S. Department of Agriculture hardiness zones 9 through 11, they can be planted permanently outdoors in mild climates, but must be brought indoors during the colder months in less temperate parts of the country. [70], Twin scales [30] This 'equine' connection refers to Carl Linnaeus the Younger who had named (in an unpublished manuscript) a West Indian species as Amaryllis equestris, because of its similarity to the African genus Amaryllis. The plant's leaves should continue to grow after the flowers have faded. The major US contribution came from the work of Henry Nehrling and Theodore Mead, whose hybrids crossed with Dutch stock have produced some modern hybrids, although not matching the European strains. Bulbs need light watering until the leaves and buds emerge, and need to be situated in a well-lit, cool place and watered as needed to maintain moderate soil moisture. candimine)[95] and psychopharmacological activity due to their high alkaloid content. [49][50][51], While interspecific hybrids of Hippeastrum are relatively common, hybridization with other genera of Amaryllidaceae are more rare. Like the naked ladies plant, the resurrection lily (Lycoris squamigera) blooms on a bare stem. Subsequent care is as for new bulbs, as described above. If you love both unique baby names and flower names for girls, Amaryllis might be a perfect choice for you. [66][verification needed], Some species, such as the Uruguayan Hippeastrum petiolatum, are sterile and unable to produce seeds. A native of Cape Floral Province in South Africa, these amaryllis can bloom at any time between summer and fall. [36], Although the 1987 decision settled the question of the scientific name of the genus, the common name "amaryllis" continues to be used. Crossing these two species with the best of the Reginae strain produced a lineage of very large open flowered specimens, with up to 4-6 flowers on each scape.
