Cutleaf Goatsbeard has masses of beautiful spikes of white flowers at the ends of the stems from late spring to mid summer, which are most effective when planted in groupings. The flowers are excellent for cutting. Its deeply cut ferny compound leaves remain emerald green in color throughout the season. The fruit is not ornamentally significant.
Cutleaf Goatsbeard is an 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 relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.
Cutleaf Goatsbeard is recommended for the following landscape applications;
Planting & Growing
Cutleaf Goatsbeard will grow to be about 3 feet tall at maturity, with a spread of 30 inches. 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 15 years.
This plant does best in partial shade to 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. Consider applying a thick mulch around the root zone over the growing season to conserve soil moisture. 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.
