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 early 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. The fruit is not ornamentally significant.

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, and should only be pruned after flowering to avoid removing any of the current season's flowers. 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;

  • General Garden Use

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 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.
