Ornamental Features

The flowers are excellent for cutting. Its oval compound leaves remain green in color throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

False Lupine 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.

False Lupine is recommended for the following landscape applications;

  • Mass Planting
  • General Garden Use

Planting & Growing

False Lupine will grow to be about 18 inches tall at maturity extending to 24 inches tall with the flowers, with a spread of 18 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 15 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.
