Description:

Lush green oakleaf shaped foliage form a neat mound; pink flower buds open to reveal the foamy shell pink and white flowers on graceful spikes; dramatic foliage, shade tolerance and repeat flowering make this one a winner

Ornamental Features

Oakleaf Foamflower has masses of beautiful spikes of lightly-scented shell pink bell-shaped flowers with white 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 lobed leaves emerge chartreuse in spring, turning dark green in colour. The foliage often turns coppery-bronze in fall. The fruit is not ornamentally significant. The dark red stems are very colorful and add to the overall interest of the plant.

Landscape Attributes

Oakleaf 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.

Oakleaf Foamflower is recommended for the following landscape applications;

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

Planting & Growing

Oakleaf Foamflower will grow to be about 8 inches tall at maturity extending to 12 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 low and dense right to the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years.

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 covering it with a thick layer of mulch 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.

Oakleaf 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.
