Cypripedium 'Dietrich' is a 2003 Werner Frosch hybrid of the European Cypripedium calceolus x Cypripedium kentuckiense. The flowers on the vigorous 2' tall stalks are quite large due to the Cypripedium kentuckiense background; although in color they resemble the smaller Cypripedium 'Rascal' with a creamy-yellow pouch and dark purple sepals. Cypripedium 'Dietrich' typically flowers in late May or early June. Our offerings are all flowering-sized plants.

Maintenance:

Lady slipper orchids are maintenance free in the garden once they are established in the correct growing conditions.

Growing Conditions:

Cypripedium prefer soils that are very well drained, and rich in compost. In containers, we like to add Permatill (popped slate) or a Pumice like product. Average moisture levels are great, but be certain soils do not remain waterlogged.

Lady slipper orchids are woodland plants, and most species do not have any sun tolerance. We have found that light, high shade is ideal.

Planting is critical, as roots must be spread horizontally just below the soil surface and not stuck deep in the ground as is the case with virtually all other plants. The growth bud should be planted just below the soil surface.

Natural Impacts:

Bees are the primary pollinators for lady slipper orchids, since orchids have a complex pollination mechanism built into the flowers.
