Galanthus, snowdrop is a small genus of approximately 20 species of bulbous perennial herbaceous plants in the family Amaryllidaceae. The plants have two linear leaves and a single small white drooping bell shaped flower with six petal-like (petaloid) tepals in two circles (whorls). The smaller inner petals have green markings.
Leucojum is a small genus of bulbous plants native to Eurasia belonging to the Amaryllis family, subfamily Amaryllidoideae. As currently circumscribed, the genus includes only two known species, most former species having been moved into the genus Acis. Both genera are known as snowflakes.
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.
Ornamental bulbous plants, often called ornamental bulbs or just bulbs in gardening and horticulture, are herbaceous perennials grown for ornamental purposes, which have underground or near ground storage organs. Botanists distinguish between true bulbs, corms, rhizomes, tubers and tuberous roots, any of which may be termed "bulbs" in horticulture. Bulb species usually lose their upper parts during adverse conditions such as summer drought and heat or winter cold. The bulb's storage organs contain moisture and nutrients that are used to survive these adverse conditions in a dormant state. When conditions become favourable the reserves sustain a new growth cycle. In addition, bulbs permit vegetative or asexual multiplication in these species. Ornamental bulbs are used in parks and gardens and as cut flowers.
Acis is a genus of perennial, herbaceous and bulbous plants in the amaryllis family. The genus consists of nine species distributed in Europe and Northern Africa. Acis was previously included in Leucojum; both genera are known as snowflakes.
Sternbergia candida is a bulbous flowering plant in the family Amaryllidaceae, subfamily Amaryllidoideae, which is used as an ornamental. It has white flowers which appear in spring.
Sternbergia clusiana is a bulbous flowering plant in the family Amaryllidaceae, subfamily Amaryllidoideae, which is sometimes used as an ornamental plant. It has greenish-yellow flowers which appear in autumn.
Sternbergia colchiciflora is a bulbous flowering plant in the family Amaryllidaceae, subfamily Amaryllidoideae, which is sometimes used as an ornamental plant. The species is native to southern Europe from Spain to Ukraine, as well as from Morocco, Algeria, Turkey, Syria, Lebanon, Palestine, Iran and the Caucasus. It has yellow flowers which appear in autumn.
Sternbergia pulchella is a bulbous flowering plant in the family Amaryllidaceae, subfamily Amaryllidoideae. It has yellow flowers which appear in autumn. The species is native to Syria and Lebanon.
Leucojum aestivum, commonly called summer snowflake or Loddon lily, is a plant species widely cultivated as an ornamental. It is native to most of Europe from Spain and Ireland to Ukraine, with the exception of Scandinavia, Russia, Belarus and the Baltic Republics. It is also considered native to Turkey, Iran and the Caucasus. It is naturalized in Denmark, South Australia, New South Wales, Nova Scotia and much of the eastern United States.
Leucojum vernum, called spring snowflake, is a perennial bulbous flowering plant species in the family Amaryllidaceae that includes the onions, daffodils and Agapanthus. It is native to central and southern Europe from Belgium to Ukraine. It is considered naturalized in north-western Europe, including Great Britain and parts of Scandinavia, and in the US states of Georgia and Florida. It is cultivated as a spring-flowering ornamental bulbous plant. Usually a single white flower with greenish marks near the tip of each tepal is borne on a stem about 10–20 cm tall, occasionally more.
Acis autumnalis, the autumn snowflake, is a species of flowering plant in the family Amaryllidaceae. A short bulbous perennial, it is found on the western shores of the Mediterranean, from Spain and Morocco to Sicily and Tunisia.
Acis fabrei is a bulbous flowering plant in the family Amaryllidaceae, native to France. It has white flowers that appear in late spring after the leaves. Although first collected in 1882, it was not scientifically described until 1990. It is now known from only four populations in the Vaucluse department in south-east France, around Mont Ventoux and the River Nesque. It is considered to be a "threatened species".
Acis ionica is a species of flowering plant in the family Amaryllidaceae, native from south-western Albania to western Greece. It was initially confused with what is now Acis valentina, a species found in Spain near Valencia.
Acis longifolia is a species of flowering plant in the family Amaryllidaceae, endemic to Corsica. Its white flowers appear in spring. It is sometimes cultivated as an ornamental plant, but is not fully frost-hardy.
Acis nicaeensis, sometimes called the French snowflake, is a species of flowering plant in the family Amaryllidaceae, native to south-eastern France. A small spring flowering bulb with white flowers, it is cultivated as an ornamental plant.
Acis tingitana is a species of flowering plant in the family Amaryllidaceae, native to north Morocco. Rare in cultivation, it is not fully frost-hardy.
Acis trichophylla is a species of flowering plant in the family Amaryllidaceae, native to Portugal, Spain and Morocco. It has very narrow leaves. The flowers are produced in late winter or early spring and are usually white, but sometimes pink-tinged or all pink. The species is cultivated as an ornamental bulb, but requires protection from hard frost.
Acis rosea, known as the rose snowflake, is a species of flowering plant in the family Amaryllidaceae, native to Corsica and Sardinia. Unlike most members of the genus Acis, it has pink rather than white flowers. It is grown as an ornamental plant but requires protection from frost.
Galanthus reginae-olgae, Queen Olga's snowdrop, is a species of flowering plant in the family Amaryllidaceae, native to Sicily and the west and north-west Balkans. Some variants produce their pendant white flowers in autumn, others in winter and early spring. It is cultivated as ornamental bulbous plant, preferring warmer situations in the garden than other species of Galanthus (snowdrops).
