|In habitat in northern Greece|
Galanthus reginae-olgae is a species of flowering plant in the family Amaryllidaceae, native to Sicily and the west and north-west Balkans (parts of Greece and the former Yugoslavia). 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).
Galanthus reginae-olgae has revolute leaves that are dark green with a central silver line and when fully grown are 11–15 cm long by 3–8 mm wide. Its flowers have three larger outer tepals, pure white, and three smaller inner tepals, white with variable green markings near the tips. The outer tepals are about 15–35 cm long, the inner ones 9–12 mm long. Populations of Galanthus reginae-olgae that flower at different times, with or without the leaves being fully developed, have been described as separate species or subspecies. Those described as G. reginae-olgae subsp. reginae-olgae flower in the autumn, either before the leaves develop or with the leaves. Those described as G. reginae-olgae subsp. vernalis flower in late winter or early spring, with the leaves.
Galanthus reginae-olgae was first described in 1876 by Theodoros G. Orphanides. The epithet reginae-olgae means 'of Queen Olga'; Olga Constantinovna of Russia was then Queen of Greece. The species (or when divided into subspecies, its autonymous subspecies) has been treated as Galanthus nivalis subsp. reginae-olgae. Other regularly used synonyms include G. olgae and G. corcyrensis. The name Galanthus corcyrensis has been particularly used for plants that flower in the autumn with the leaves rather than before them.
The species has been divided into two subspecies, distinguished by the time of flowering:
- Galanthus reginae-olgae subsp. reginae-olgae – flowering in autumn
- Galanthus reginae-olgae subsp. vernalis Kamari – flowering in late winter to spring
There is however no sharp division between these two subspecies.
Distribution and habitat
Galanthus reginae-olgae is cultivated as an ornamental bulbous plant, particularly the autumn-flowering variants. In cultivation, it requires a warmer and sunnier position than most other Galanthus species. The cultivar 'Cambridge', originating from the Cambridge University Botanic Garden, has large green markings on the inner tepals.
