Other Names:  Eupatorium purpureum, Boneset

Description:

Compact growth habit compared to the species, ideal for smaller gardens; features fluffy plumes of lavender-purple flowers, attractive leaves and strong stems; tasty seeds for birds and nectar for butterflies

Ornamental Features

Phantom Eupatorium has masses of beautiful plumes of lightly-scented lavender flowers with purple overtones at the ends of the stems from late summer to late fall, which emerge from distinctive fuchsia flower buds, and which are most effective when planted in groupings. The flowers are excellent for cutting. Its serrated narrow leaves emerge dark green in spring, turning forest green in color throughout the season. The burgundy stems can be quite attractive.

Landscape Attributes

Phantom Eupatorium is an herbaceous perennial with an upright spreading habit of growth. Its relatively coarse texture can be used to stand it apart from other garden plants with finer foliage.

This plant will require occasional maintenance 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, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Phantom Eupatorium is recommended for the following landscape applications;

• Mass Planting
• Hedges/Screening
• General Garden Use

Planting & Growing

Phantom Eupatorium will grow to be about 30 inches 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 medium rate, and under ideal conditions can be expected to live for approximately 15 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 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.
