Cypripedium 'Ulla Silkens'
Common Name: Hybrid Lady's Slipper Family: Orchidaceae (The Orchid Family)

Cypripedium  'Ulla Silkens'
Zoom In Photo:

'Ulla Silkens' is like an improved C. reginae. Pure white tepals provide the backdrop for a lip that can be white with rich pink speckles or even completely rich pink depending on your plant. In addition, the lip colour is more intense in cool temperatures and paler in higher temperatures offering a different show every year. Late flowering. More sun tolerant. Rich soil. Plants will resemble the image but may not be identical. One of the tallest hybrids, it is a cross between C. reginae and C. flavum. Lady's slipper hybrids are much more vigorous and easy to grow than species. Blooming size.
