Hardiness Zone:  4a

Other Names:  Aster trifoliatus subsp. ageratoides

Description:

Profusion of dark purple-lavender flowers in mid to late fall, over attractive green foliage; prefers cool, moist soil; not for small gardens as it will fill a large space rapidly; very frost resistant

Ornamental Features

Ezo Murasaki Aster has masses of beautiful purple daisy flowers with lavender overtones and yellow eyes at the ends of the stems from early to late fall, which are most effective when planted in groupings. The flowers are excellent for cutting. Its narrow leaves remain forest green in color throughout the season.

Landscape Attributes

Ezo Murasaki Aster is a dense herbaceous perennial with a ground-hugging habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This is a relatively low maintenance plant, 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, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Spreading
  • Disease

Ezo Murasaki Aster is recommended for the following landscape applications;

  • Mass Planting
  • General Garden Use
  • Groundcover
  • Container Planting

Planting & Growing

Ezo Murasaki Aster will grow to be about 24 inches tall at maturity, with a spread of 6 feet. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!

This plant does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America. 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.

Ezo Murasaki Aster is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
