Popular hardy orchids belong to the following genus:
Cypripedium hybrides, Dactylorhiza, Epipactis, Gymnadenia, Orchis, Pleione, Pogonia and Spiranthes, Platanthera.
There are over 40 species of hardy orchids. (excluding hybrid varieties).
In nature, orchids choose places that may vary according to species. These are damp areas, wet meadows, and forests with lots of light coming in or areas that are strongly sunlit. Most of them like calcium-rich soils, but some of them require neutral soil.
Purchased plants should be planted in the right place to provide sufficient light and moisture to the substrate.
Immediately after planting orchids we water them abundantly and take care of the soil to be moist all the time when plant blooms.
After the period of flowering the orchid leaves become dry and plants are in a state of rest until next flowering in the spring.
As far as fertilization is concerned, we can apply highly diluted multi-ingredient fertilizers. Orchids are fertilized only in the early spring.
Hardy orchids do not have to adjust to the climate of Europe or Northern America. Once planted in the garden they do not require special attention. Orchids are completely frost-resistant. They can withstand temperatures up to -40 C. Orchid flowers are very nice and original. Choosing the right species of orchids we can cause them to bloom from April to October.
When buying orchids for the garden, we have to point out that individual species have different light requirements, the amount of water in soil and the reaction of the soil. For example, orchids of the genus Dacylorhiza need a lot of light and well-aired substrate. The substrate must remain wet. These orchids are well suited to plant the edges of the pond. They can grow in full sun or lightly shaded areas.
On the contrary Cypripedium orchids need well drained alkaline substrate. The best place for them is partly shade. In winter they can not suffer the excess of water.
