C. reginae x C. flavum

'Frosch's Ulla Spots' is a special selection of Cypripedium Ulla Silkens, making it one of the most robust garden lady's slippers of all, albeit not as fast growing as 'Frosch's Ulla Freckles'. It is extremely hardy to the effects of climate change because it doesn’t start shooting until comparatively late in the year, warm winter spells and late spring frosts will not affect it. Similarly, it tolerates heat and sun in summer much better than other varieties. It’s also relatively insensitive to temporarily wet or dry soil. In short, it is the ideal plant for beginners and for spots where other hardy lady's slippers can no longer thrive!

Due to its hairy leaves, 'Frosch's Ulla Spots' requires a bit more light than the other cypripediums. It even tolerates direct morning and evening sun. In contrast it won’t flourish in deep shade such as beneath shrubs. It will tolerate quite damp soil, for example at the edge of a pond.

'Frosch's Ulla Spots' is the tallest among the listed garden orchids and can grow up to 60 cm (23 in) tall. To reach this size it needs an especially large amount of fertilizer.

Zones 3-6. 16-24 in. Light shade, cool moist rich well-drained soil.
