Orchidaceae: An upright, clump-forming perennial to 75cm with downy stems. Grows in shady woodland and scrub. The flowers have a comprising broad. Greenish sepals tinged purple around the margins, broad purple-tinged upper petals, and a purplish, heart-shaped lip, these form dense spikes of up to 100 flowers, blooming from July-September. The seed pods are pear-shaped. The leaves are broadly oval and strongly veined. A locally common orchid in most parts of the country, except Northern Scotland. widespread across much of Europe and Asia from Portugal to China, as well as northern Africa. In North America, it is widely naturalized mostly in the North-eastern United States, eastern Canada and the Great Lakes Region.
Before you read any further, you need to understand that unless you are a professional orchid grower, with all the right gear to grow orchids form seed, this is 100% experimental enterprise, and there are no guarantees for success!
Orchids have dust like seed that can dispersed over extremely long distances on the wind. These seeds can survive for perhaps 5 year or more. They must form an endomycorrhizal relationship with a specific soil fungi soon after germination. The first few years after germination are spent below ground, with the young orchid gaining nutrition from its fungal partner. The symbiotic relationship continues as the growing orchid produces it first leaves, normally after 3-5 years, and flowering, perhaps between 3-8 years after germination. Most orchid species will continue to flower and bulk up year after year, but the beautiful Bee orchid sadly only flowers once.
There is no easy way of knowing if your site can provide the right conditions for orchids, or if the soil contains the right fungus, the fungus is, however, very common, even in the absence of orchids. Also, it appears that grassland species may establish and grow better in association with species such as Leonntodon hisidus, and other rosette forming species, in short, open, flower rich swards on poor soils.
When sowing, orchid seed do take all the above into account, but let nature sort out the detail. Sprinkle the seed finely over the surface of your chosen spot. Allow lightly water with rain water to help wash the seed through the vegetation and into the soil. To manage the site, from year to year, at the end of August cut the grass down. Fingers crossed and hopefully you will have your very own orchids in around 3-8 years from sowing.
