Ornamental Features:

Sea Foam Foamflower features beautiful spikes of lightly-scented white bell-shaped flowers 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. It's attractive tomentose lobed leaves remain forest green in color with distinctive deep purple veins throughout the year.

Landscape Attributes:

Sea Foam Foamflower is an herbaceous evergreen perennial with tall flower stalks held atop a low mound of foliage. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This is a relatively low maintenance perennial, 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.

Sea Foam Foamflower is recommended for the following landscape applications;

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

Plant Characteristics:

Sea Foam Foamflower will grow to be only 6 inches tall at maturity extending to 12 inches tall with the flowers, with a spread of 15 inches. 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 perennial 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 zones. This plant can be propagated by division.

This particular variety is an interspecific hybrid.
