Landscape Qualities
Millenium Ornamental Onion is an open herbaceous perennial with tall flower stalks held atop a low mound of foliage. Its relatively coarse texture can be used to stand it apart from other garden plants with finer foliage.
Ornamental Qualities
Millenium Ornamental Onion features bold balls of lightly-scented lilac purple flowers with purple overtones at the ends of the stems in mid summer. The flowers are excellent for cutting. Its attractive glossy sword-like leaves remain dark green in color throughout the season.
Planting and Growing
Millenium Ornamental Onion will grow to be about 12 inches tall at maturity extending to 20 inches tall with the flowers | with a spread of 15 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 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.
