Ornamental Features

Lavender Globe Onion has masses of beautiful balls of lightly-scented lavender 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 grassy leaves remain green in colour throughout the season.

Landscape Attributes

Lavender Globe Onion is an open 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. Trim off the flower heads after they fade and die to encourage more blooms late into 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.

Lavender Globe Onion is recommended for the following landscape applications;

• Border Edging
• General Garden Use
• Container Planting

Planting & Growing

Lavender Globe Onion will grow to be about 12 inches tall at maturity extending to 18 inches tall with the flowers, with a spread of 12 inches. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 5 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! As this plant tends to go dormant in summer, it is best interplanted with late-season bloomers to hide the dying foliage.

This plant should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments. This species is not originally from North America. It can be propagated by division.

Lavender Globe Onion 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 against which the larger 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.
