Ornamental Features

Purpleleaf Loosestrife has masses of beautiful yellow flowers along the stems from early to mid summer, which are most effective when planted in groupings. The flowers are excellent for cutting. Its attractive pointy leaves emerge burgundy in spring, turning dark green in color with distinctive deep purple edges throughout the season. The fruit is not ornamentally significant. The deep purple stems are very colorful and add to the overall interest of the plant.

Landscape Attributes

Purpleleaf Loosestrife is a dense herbaceous perennial with an upright spreading habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This is a high maintenance plant that will require regular care and upkeep, and is best cleaned up in early spring before it resumes active growth for the season. It is a good choice for attracting butterflies to your yard. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Spreading

Purpleleaf Loosestrife is recommended for the following landscape applications;

  • Mass Planting
  • General Garden Use
  • Container Planting
  • Bog Gardens

Planting & Growing

Purpleleaf Loosestrife will grow to be about 3 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 24 inches apart. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 5 years.

This plant does best in full sun to partial shade. It is quite adaptable, prefering to grow in average to wet conditions, and will even tolerate some standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a selection of a native North American species. 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.

Purpleleaf Loosestrife is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception. Contact our store for more information on how to protect it over the winter months.
