Cypripedium ‘Ulla Silkens’: A remarkable offspring

The Hybrid vigor...

Cypripedium hybrids resulting from a cross between 2 wild or botanical species are generally characterized by their increased vigor ('hybrid vigor').

This results in a more rapid proliferation compared to botanical varieties. Since more new stems appear, it is not uncommon, with hybrid varieties, to obtain flowerbeds with 10-20 flower stems after only a few years.

The ‘Ulla Silkens' cypripedium is the product of a cross between a pink-red variety of American origin (Cypripedium reginae) and a yellow variety present in Russia and in the Himalaya mountains (Cypripedium flavum).

The result is a beautiful flower with white to slightly pink sepals and petals covered with a variable number of purple red spots. Since it is a hybrid consisting of the characteristics of each of the parent plant; one should note that the number of spots may vary from a few to over thirty from one plant to another. The slipper-shaped flowers bloom in April/May. This very hardy orchid can withstand temperatures down to -30 °C.

What should I do when I receive my Cypripedium orchids?

We recommend replanting our perennial orchids in your garden as soon as you receive the order, to avoid the rhizome drying in the growing pot.

Cypripedium orchids live naturally in cold regions, and when growing in the ground can tolerate sub-zero temperatures. Moreover, they absolutely must go through winter cold to be able to thrive the next spring.

Cypripedium orchids are usually present in undergrowth and environments that remain cool in the summer. We suggest that you plant them in areas protected from too much mid-day sunlight, so that they’re not exposed to excessive temperatures. A bit of early morning or evening sunshine is enough.

The soil must be light and moist (especially during the summer). Using fine lava or pumice will keep the substrate moist, even during dry periods.

You can prepare a simple substrate by mixing around 1/3 lava or pumice, 1/3 soil for aquatic plants (which usually contain a bit of clay and sand), and 1/3 garden soil.
