How to Grow Cypripedium Plants in your Garden

Gardener's HQ Guide to Growing Lady’s Slipper Orchid, Moccasin flower, Squirrel Foot, and Pelican Orchid

Cypripedium are hardy perennial wild orchids. They range from 30 to 80 cm !2 to 30 inches) in height.

They flower in the late spring, with their slipper being one colour and their petals another. This creates a beautiful two coloured flower.

There is a large range of colour in Cypripedium orchids, including brown, pink, purple, white, and yellow.

Some of the more common names of Cypripedium plants include Lady's-slipper orchids, and the moccasin flower.

Description of Lady's-slipper orchids - Moccasin flower (Cypripedium)

Plants of the Cypripedium are very difficult to grow and look after.

If you do want to try to grow them from seed, then it is best to sterilise the seeds first (use a very very weak bleach solution, or vinegar), then lay the seed on blotting paper that has been soaked in boiling water (it is important that the whole operation remains as sterile as possible).

The seeds should then be placed in a sterile box in the light at about 20 degrees Centigrade (68°F).

Alternatively if you have access to laboratory equipment, you may want to dissect the embryo from the seed and grow on a GM plate; or even give the seed a treatment with gibberellc acid to promote seed germination.

If seeds do not germinate quickly, then be aware that it can take anything from one month to one year to do so, so bear with them and keep checking back.

If you do manage to get lady's-slipper orchids / Moccasin flower seedlings, then you should plant them in the garden in the autumn at a spacing of about 40 cm (16 inches) apart. Locate into a woody acidic soil. Ideally this should be cool so grow in the shade.
