Frog orchid Coeloglossum viride
|Best Time to See|
An orchid of unimproved, short grassland, preferring chalky soils.
Frog orchids are easily overlooked as the colours of its short flowering spike matches the grasses and wildflowers with which it grows. If you look carefully, you may find quite large populations, but, as with other orchids, flowering may vary from year to year.
How to spot it
The flowers are green, but often tinged with purple, red or brown and, as the name suggests, look like small frogs when you get up close. The flowering spike only grows to between 4 and 20 cm tall and varies considerably in size, carrying between five and twenty-five individual flowers. The plant has three to five dark green leaves, those at the base of the plant blunt, but the ones higher up the stem narrow and pointed.
Where it grows
Frog orchids are locally frequent throughout Britain and Ireland. They are native to a range of limestone habitats such as calcareous grasslands, vegetated clints in limestone pavement, roadsides and quarries in limestone areas.
Best time to see
In flower from June to August
How's it doing?
The frog orchid has declined considerably, particularly in central England and East Anglia. Many losses occurred before 1930, but have continued since then, largely due to habitat destruction and the ploughing and improvement of old pastures.
