Hardiness Zone: 4 Other Names: Flowering Onion Brand: Walters Gardens Description: Beautiful, light amethyst purple flower globes are produced above twisted, snaky, grey-green foliage in late summer to early fall; an excellent naturalizing plant that is also great in containers Ornamental Features Medusa Ornamental Onion features bold balls of lightly-scented lavender flowers with purple overtones at the ends of the stems from late summer to early fall. The flowers are excellent for cutting. Its attractive twisted sword-like leaves remain grayish green in colour throughout the season. Landscape Attributes Medusa Ornamental Onion is an open herbaceous perennial with tall flower stalks held atop a low mound of foliage. 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. Medusa Ornamental Onion is recommended for the following landscape applications; Planting & Growing Medusa Ornamental Onion will grow to be about 14 inches tall at maturity extending to 24 inches tall with the flowers, with a spread of 24 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 18 inches apart. 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 does best in full sun to partial shade. It prefers dry to average moisture levels with very well-drained soil, and will often die in 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 particular variety is an interspecific hybrid. It can be propagated by multiplication of the underground bulbs; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation. Medusa Ornamental Onion is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
