Crocus chrysanthus, the snow crocus or golden crocus, [2] is a species of flowering plant in the family Iridaceae . [1] [3]
C. chrysanthus bears vivid orange-yellow bowl-shaped flowers, and it has smaller[ specify ] corms and a smaller[ specify ] flower than the giant Dutch crocus ( Crocus vernus ), although it produces more flowers per corm[ specify ] than the latter. Its common name, "snow crocus", derives from its exceptionally early flowering period, blooming about two weeks before the giant crocus,[ specify ] and often emerging through the snow in late winter or early spring. The leaves are narrow[ specify ] with a silver central stripe. Its height is between 3 and 4 inches (7.6 and 10.2 cm). [4]
The specific epithet chrysanthus means "golden-flowered". [5]
It is native to southeastern Europe and Turkey, and is an introduced species in Czechoslovakia, Germany, and Great Britain. [1]
Crocus chrysanthus cultivars are selections from Crocus chrysanthus and hybrids of this species with several subspecies of Crocus biflorus and Crocus aerius . Yellow cultivars are selections of Crocus chrysanthus. Blue and white cultivars are hybrids or selections close to Crocus biflorus .[ citation needed ]
An intensive hybridisation and selection programme was initiated by Jan Hoog (Van Tubergen nursery) and E.A. Bowles involving crosses between C. chrysanthus and a number of forms of C. biflorus; the results with larger flowers and usually flower markings and colors were named. [7]
Several of their numerous selections are still available. Examples include the following: [7]
Those cultivars marked agm have gained the Royal Horticultural Society's Award of Garden Merit.
Geranium is a genus of 422 species of annual, biennial, and perennial plants that are commonly known as geraniums or cranesbills. They are found throughout the temperate regions of the world and the mountains of the tropics, with the greatest diversity in the eastern part of the Mediterranean region.
Crocus is a genus of seasonal flowering plants in the family Iridaceae comprising about 100 species of perennials growing from corms. They are low growing plants, whose flower stems remain underground, that bear relatively large white, yellow, orange or purple flowers and then become dormant after flowering. Many are cultivated for their flowers, appearing in autumn, winter, or spring. The flowers close at night and in overcast weather conditions. The crocus has been known throughout recorded history, mainly as the source of saffron. Saffron is obtained from the dried stigma of Crocus sativus, an autumn-blooming species. It is valued as a spice and dyestuff, and is one of the most expensive spices in the world. Iran is the center of saffron production. Crocuses are native to woodland, scrub, and meadows from sea level to alpine tundra from the Mediterranean, through North Africa, central and southern Europe, the islands of the Aegean, the Middle East and across Central Asia to Xinjiang in western China. Crocuses may be propagated from seed or from daughter cormels formed on the corm, that eventually produce mature plants. They arrived in Europe from Turkey in the 16th century and became valued as an ornamental flowering plant.
Hibiscus syriacus is a species of flowering plant in the mallow family, Malvaceae. It is native to areas of east Asia, but widely introduced elsewhere, including much of Europe and North America. It was given the epithet syriacus because it had been collected from gardens in Syria. Common names include the rose of Sharon,, Syrian ketmia, shrub althea (or simply althea), and rose mallow. It is the national flower of South Korea and is mentioned in the South Korean national anthem.
Osteospermum, is a genus of flowering plants belonging to the Calenduleae, one of the smaller tribes of the sunflower/daisy family Asteraceae. They are known as the daisybushes or African daisies. Its species have been given several common names, including African daisy, South African daisy, Cape daisy and blue-eyed daisy.
Dasiphora fruticosa is a species of hardy deciduous flowering shrub in the family Rosaceae, native to the cool temperate and subarctic regions of the northern hemisphere, often growing at high altitudes in mountains. Dasiphora fruticosa is still widely referenced in the horticultural literature under its synonym Potentilla fruticosa. Common names include shrubby cinquefoil, golden hardhack, bush cinquefoil, shrubby five-finger, widdy, kuril tea and tundra rose.
Lobularia maritima is a species of low-growing flowering plant in the family Brassicaceae. Its common name is sweet alyssum or sweet alison, also commonly referred to as just alyssum.
Euonymus japonicus is a species of flowering plant in the family Celastraceae, native to Japan and Korea.
Cornus alba, the red-barked, white or Siberian dogwood, is a species of flowering plant in the family Cornaceae, native to Siberia, northern China and Korea. It is a large deciduous surculose (suckering) shrub that can be grown as a small tree. As a popular ornamental used in landscaping its notable features include the red stems in fall (autumn) through late winter, bright winter bark; and the variegated foliage in some cultivars, such as C. alba 'Elegantissima'. C. alba can grow to 3 m (10 ft) high, but variegated forms are less vigorous. For the brightest winter bark, young shoots are encouraged by cutting to the ground some older stems at the end of the winter, before leaves are open. The oval fruits are white, sometimes tinted blue.
Farfugium japonicum is a species of flowering plant in the family Asteraceae, also known as leopard plant, green leopard plant or tractor seat plant. It is native to streams and seashores of Japan, where it is called tsuwabuki (石蕗).
Crocosmia × crocosmiiflora, montbretia, is a garden hybrid of C. aurea and C. pottsii, first bred in 1880 in France by Victor Lemoine. The basionym of the hybrid is Montbretia crocosmiiflora Lemoine. In 1932 it was reclassified as C. × crocosmiiflora (Lemoine) N.E.Br., but the common name "montbretia" is still often found in horticultural literature, and is commonly used in the British Isles for orange-flowered cultivars that have naturalised, while "crocosmia" is reserved for less aggressive red-flowered cultivars.
Crocus sieberi, Sieber's crocus, also referred to as the Cretan crocus or snow crocus, is a plant of the genus Crocus in the family Iridaceae. A small, early blooming crocus, it easily naturalises, and is marked by a brilliant orange which is mostly confined to the stamens and style, fading through the bottom third of the tepal. It grows wild generally in the Balkans: Greece, especially in the island of Crete, Bulgaria, Albania and North Macedonia. There are four subtypes: sieberi (Crete), atticus, nivalis and sublimis. Its cultivars are used as ornamental plants. Height: 3–4 inches (7.6–10.2 cm).
Coprosma repens is a species of flowering shrub or small tree of the genus Coprosma, in the family Rubiaceae, native to New Zealand. Common names include taupata, tree bedstraw, mirror bush, looking-glass bush, New Zealand laurel and shiny leaf.
Colchicum speciosum is a species of flowering plant in the family Colchicaceae, native to mountainous areas of northern Turkey, the Caucasus and northern Iran. Growing to 18 cm (7 in) tall by 10 cm (4 in) wide, it is an herbaceous perennial growing from corms. C. speciosum blooms in the fall, producing reddish/violet flowers on stems up to 30 centimetres (12 in) tall without any leaves present. The strap-like leaves grow in the spring, then yellow, wither and die back as summer progresses. The flowers strongly resemble those of the crocus, the familiar spring-flowering bulb; hence the common name autumn crocus which is applied to this and other colchicum species. However the two genera belong to different families; and there is in fact an autumn-flowering crocus species, Crocus sativus, the source of the spice saffron. By contrast, all parts of Colchicum speciosum are toxic if ingested.
Acer palmatum, commonly known as Japanese maple, palmate maple, or smooth Japanese maple (Korean: danpungnamu, 단풍나무, Japanese: irohamomiji, イロハモミジ, or momiji,, is a species of woody plant native to Korea, Japan, China, eastern Mongolia, and southeast Russia. Many different cultivars of this maple have been selected and they are grown worldwide for their large variety of attractive forms, leaf shapes, and spectacular colors.
Tecophilaea cyanocrocus, the Chilean blue crocus, is a flowering perennial plant that is native to Chile, growing at 2,000 to 3,000 m elevation on dry, stony slopes in the Andes mountains. Although it had survived in cultivation due to its use as a greenhouse and landscape plant, it was believed to be extinct in the wild due to overcollecting, overgrazing, and general destruction of habitat, until it was rediscovered in 2001.
Crocus angustifolius, the cloth-of-gold crocus, is a species of flowering plant in the genus Crocus of the family Iridaceae, native to southern Ukraine and Armenia.
