Blue Drumstick Ornamental Onion features bold balls of lightly-scented blue flowers at the ends of the stems from late spring to early summer. The flowers are excellent for cutting. Its grassy leaves remain green in colour throughout the season. The fruit is not ornamentally significant.
Blue Drumstick 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.
Blue Drumstick Ornamental Onion is recommended for the following landscape applications;
Planting & Growing
Blue Drumstick Ornamental Onion will grow to be about 12 inches tall at maturity extending to 24 inches tall with the flowers, with a spread of 6 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 is a selected variety of a species not originally from North America. 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.
