Galanthus, or 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.
Muscari neglectum is a perennial bulbous flowering plant in the asparagus family Asparagaceae. Members of this genus are commonly known as grape hyacinths, and M. neglectum is known as common grape hyacinth or starch grape hyacinth. Muscari are perennial bulbous plants native to Eurasia. They produce spikes of dense, commonly blue, urn-shaped flowers. It is sometimes grown as an ornamental plant, for example, in temperate climates as a spring bulb.
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, stem 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.
Brian Frederick Mathew MBE, VMH is a British botanist, born in the village of Limpsfield, Surrey, England. His particular area of expertise is bulbous plants, particularly ornamental bulbous plants, although he has contributed to other fields of taxonomy and horticulture. He has authored or co-authored many books on bulbs and bulbous genera which appeal to both botanists and gardeners, as well as specialist monographs on other genera, including Daphne, Lewisia, and Helleborus. His work has been recognized by the British Royal Horticultural Society and the International Bulb Society.
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.
Leucojum aestivum, commonly called the summer snowflake, giant snowflake, Loddon lily and rarely snowbell and dewdrop among others, 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 countries. 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, commonly called the spring snowflake, St. Agnes' flower, and rarely snowbell among others, is a species of flowering plant in the family Amaryllidaceae. 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. This spring flowering bulbous herbaceous perennial is cultivated as an ornamental for a sunny position. The plant multiplies in favourable conditions to form clumps. Each plant bears a single white flower with greenish marks near the tip of the tepal, on a stem about 10–20 cm (3.9–7.9 in) tall, occasionally more.
Galantheae is a tribe of European, West Asian and North African flowering plants belonging to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae). As of 2017, it contains three genera, although more were included previously. The position of the ovary is inferior.
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 Portugal, 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 tingitana is a species of flowering plant in the family Amaryllidaceae, native to northern Morocco. Rare in cultivation, it is not fully frost-hardy.
Acis trichophylla, commonly called the triangular-leaved snowflake, 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 valentina is a species of bulbous flowering plant in the family Amaryllidaceae, native to eastern Spain. Its white flowers appear in autumn. It can be grown as an ornamental bulb, but may need 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).
