Ornamental Features

Foamflower has masses of beautiful spikes of lightly-scented white star-shaped flowers rising above the foliage from mid spring to mid summer, which emerge from distinctive shell pink flower buds, and which are most effective when planted in groupings. Its crinkled heart-shaped leaves remain green in colour throughout the year. The fruit is not ornamentally significant.

Landscape Attributes

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.

Foamflower is recommended for the following landscape applications;

  • Mass Planting
  • Border Edging
  • General Garden Use

Planting & Growing

Foamflower will grow to be about 11 inches tall at maturity, with a spread of 7 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 fast 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 species is native to parts of North America. It can be propagated by division.
