Ornamental Features

Landscape Attributes

Carolina Bushpea is an herbaceous perennial with an upright spreading habit of growth. 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 should only be pruned after flowering to avoid removing any of the current season's flowers. It has no significant negative characteristics.

Carolina Bushpea is recommended for the following landscape applications;

  • Mass Planting
  • General Garden Use

Planting & Growing

Carolina Bushpea will grow to be about 4 feet tall at maturity, with a spread of 3 feet. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 30 inches apart. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years. As this plant tends to go dormant in summer, it is best interplanted with late-season bloomers to hide the dying foliage.

This plant does best in full sun to partial shade. It is very adaptable to both dry and moist growing conditions, but will not tolerate any standing water. It is particular about its soil conditions, with a strong preference for sandy, alkaline soils. It is somewhat tolerant of urban pollution. This species is native to parts of North America.
