Large, unusual star shaped leaves with a dark vein down each lobe form a neat mound of foliage; pink flower buds open to reveal the pinkish-white flowers on graceful spikes; dramatic foliage, shade tolerance and repeat flowering make this one a winner

Ornamental Features

Dark Star Foamflower has masses of beautiful spikes of lightly-scented white bell-shaped flowers with shell pink overtones rising above the foliage from mid spring to mid summer, which emerge from distinctive pink flower buds, and which are most effective when planted in groupings. The flowers are excellent for cutting. Its attractive large lobed leaves emerge chartreuse in spring, turning dark green in colour with distinctive burgundy veins. The foliage often turns coppery-bronze in fall. The burgundy stems are very colorful and add to the overall interest of the plant.

Landscape Attributes

Dark Star Foamflower is an herbaceous evergreen perennial with tall flower stalks held atop a low mound of foliage. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.

This is a relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.

Dark Star Foamflower is recommended for the following landscape applications;

  • Mass Planting
  • Rock/Alpine Gardens
  • Border Edging
  • General Garden Use
  • Groundcover
  • Container Planting

Planting & Growing

Dark Star Foamflower will grow to be about 12 inches tall at maturity extending to 16 inches tall with the flowers, with a spread of 12 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 10 inches apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years. As an evegreen perennial, this plant will typically keep its form and foliage year-round.

This plant does best in partial shade to shade. It requires an evenly moist well-drained soil for optimal growth. It is particular about its soil conditions, with a strong preference for rich, acidic soils. It is somewhat tolerant of urban pollution, 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 microclimates. This particular variety is an interspecific hybrid. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Dark Star Foamflower is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers and foliage against which the larger thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception. Contact our experts for more information on how to protect it over the winter months.
