Landscape Attributes
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.

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.

Planting & 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.

Millenium 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.

Want more info on sizes?
IndyPlants sells landscape size plant material. These often come in black nursery containers and are classified in sizes such as #2, #3, #5, etc. This correlates to the volume of the container, 2 gallon, 3, gallon, 5 gallon, etc. The bigger the number, the larger the pot, and the larger the plant. You’ll also see larger sizes such as 2” BB, 2.5” BB, 3” BB, etc. This stands for ‘Balled & Burlapped’. These plants are usually much larger and are not transported in black nursery pots. The sizing correlates to the diameter of the trunk of the tree.
