Plant Characteristics:
Ulla Silkens Lady's Slipper will grow to be about 12 inches tall at maturity extending to 18 inches tall with
the flowers, with a spread of 12 inches. It grows at a slow rate, and under ideal conditions can be
expected to live for approximately 15 years.
This perennial should be grown in a location that is shaded from the hot afternoon sun. It requires an
evenly moist well-drained soil for optimal growth, but will die in standing water. It is particular about its
soil conditions, with a strong preference for rich, neutral soils. It is quite intolerant of urban pollution,
therefore inner city or urban streetside plantings are best avoided, and will benefit from being planted in a
relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in
exposed locations or colder zones. This plant can be propagated by multiplication of the underground
bulbs.
This particular variety is an interspecific hybrid.
