Landscape Attributes

Milly Rock™ Yellow Yarrow is an herbaceous perennial with a mounded form. 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 bees, butterflies and hummingbirds 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
• Self-Seeding

Milly Rock™ Yellow Yarrow is recommended for the following landscape applications;

• Mass Planting
• Border Edging
• General Garden Use
• Groundcover
• Naturalizing And Woodland Gardens
• Container Planting

Planting & Growing

Milly Rock™ Yellow Yarrow will grow to be about 8 inches tall at maturity extending to 12 inches tall with the flowers, with a spread of 14 inches. It grows at a fast 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 should only be grown in full sunlight. It prefers to grow in average to dry locations, and dislikes excessive moisture. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil pH, but grows best in poor soils. It is highly tolerant of urban pollution and will even thrive in inner city environments. 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.

Milly Rock™ Yellow Yarrow is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers and foliage against which the thriller plants stand out. 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.
