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.
Colchicum autumnale, commonly known as autumn crocus, meadow saffron, naked boys or naked ladies, is a toxic autumn-blooming flowering plant that resembles the true crocuses, but is a member of the plant family Colchicaceae, unlike the true crocuses, which belong to the family Iridaceae. It is called "naked boys/ladies" because the flowers emerge from the ground long before the leaves appear. Despite the vernacular name of "meadow saffron", this plant is not the source of saffron, which is obtained from the saffron crocus, Crocus sativus – and that plant, too, is sometimes called "autumn crocus".
Magnolia wilsonii, or Wilson's magnolia, is a species of Magnolia native to China, in the provinces of western Guizhou, Sichuan and northern Yunnan, where it grows in the forest understory at altitudes of 1,900-3,000 m, rarely up to 3,300 m.
Scilla siberica, the Siberian squill or wood squill, is a species of flowering plant in the family Asparagaceae, native to southwestern Russia, the Caucasus, and Turkey. Despite its name, it is not native to Siberia.
Scilla luciliae is a species of flowering plant in the family Asparagaceae. It is referred to by the common names Bossier's glory-of-the-snow or Lucile's glory-of-the-snow, and is a bulbous perennial from western Turkey that flowers in early spring. After flowering, it goes into dormancy until the next spring. The specific epithet is in honour of Lucile, the wife of the Swiss botanist Pierre Edmond Boissier (1810-1885). It belongs to a group of Scilla species that were formerly put in a separate genus, Chionodoxa, and may now be treated as Scilla sect. Chionodoxa.
Ornithogalum dubium, common names sun star, star of Bethlehem or yellow chincherinchee, is a species of flowering plant in the family Asparagaceae, subfamily Scilloideae. It is a South African endemic.
Olsynium douglasii is a species of flowering plant in the iris family (Iridaceae). Common names include Douglas' olsynium, Douglas' grasswidow, grass-widow, blue-eyed grass, purple-eyed-grass, and satin flower, It is the only species in the genus Olsynium in North America, the remaining 11 species being from South America. It was formerly treated in the related genus Sisyrinchium. Despite the common names, it is not a true grass (Poaceae).
Sternbergia lutea, the winter daffodil, autumn daffodil, fall daffodil, lily-of-the-field, or yellow autumn crocus, is a bulbous flowering plant in the family Amaryllidaceae, subfamily Amaryllidoideae, in the Narcisseae tribe, which is used as an ornamental plant. It has yellow flowers which appear in autumn.
Geranium endressii, commonly called Endres cranesbill or French crane's-bill, is a species of hardy flowering herbaceous or semi-evergreen perennial plant in the genus Geranium, family Geraniaceae.
Crocus chrysanthus, the snow crocus or golden crocus, is a species of flowering plant of the Crocus genus in the family Iridaceae. Native to the Balkans and Turkey, it bears vivid orange-yellow bowl-shaped flowers. It has smaller corms and a smaller flower than the giant Dutch crocus, although it produces more flowers per corm than the latter. Its common name, "snow crocus", derives from its exceptionally early flowering period, blooming about two weeks before the giant crocus, and often emerging through the snow in late winter or early spring. The leaves are narrow with a silver central stripe. Height: 3–4 inches (7.6–10.2 cm).
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).
Crocus tommasinianus, the woodland crocus, early crocus, or Tommasini's crocus, is a flower named after the botanist Muzio G. Spirito de Tommasini (1794-1879). It is native to Bulgaria, Hungary, Albania, and the former Yugoslavia. It is often referred to as the early or snow crocus, but these terms are shared with several other species, although C. tommasinianus is amongst the first to bloom. Multiple plants are often called tommies in the horticultural trade.
Colchicum cilicicum, the Tenore autumn crocus, is a species of flowering plant in the Colchicaceae family. A bulbous perennial, it bears deep rose-lilac flowers in late summer, with barely any chequered pattern on the petals (tessellation). It has a very noticeable white stripe down the centre of each petal, which gives it a star-like appearance at the base. The flowers tend to stand up to weather better than other colchicum blooms. The flowers appear before the strap-like leaves, giving this and other colchicum species the common name “naked lady”. Although colchicums are called “autumn crocuses” they belong to a different family than true crocuses. There are in fact autumn-flowering species of crocus such as Crocus sativus, which is the source of the spice saffron. Colchicum cilicicum, by contrast, is toxic if eaten.
Colchicum × byzantinum, the Byzantine meadow saffron, is a species of flowering plant in the family Colchicaceae with a long history of cultivation, and no certain place of origin. It is thought to be a hybrid of other species.
Crocus biflorus, the silvery crocus or scotch crocus, is a species of flowering plant in the family Iridaceae. It is native to south-eastern Europe and south-western Asia, including Italy, the Balkans, Ukraine, Turkey, Caucasus, Iraq, and Iran. It is a cormous perennial growing to 6 cm (2.4 in) tall and wide. It is a highly variable species, with flowers in shades of pale mauve or white, often with darker stripes on the outer tepals. The flowers appear early in spring.
Crocus corsicus is a species of flowering plant in the genus Crocus of the family Iridaceae, endemic to the Mediterranean islands of Corsica and Sardinia.
