Why the Millenium Ornamental Onion?

If you think onions are only for eating, then you’ve got another thing coming. There are many fantastic ornamental onions for your garden that can deliver a splash of color along with quirky forms for a playful touch. Millenium Ornamental Onion is one of the best. It will charm you from mid- to late summer with rosy purple blooms shaped like lollipops. The perky flower heads attract butterflies, bees, and other valuable pollinators, too. Plant this compact grower near the front of your mixed border or keep it in a container and have a fun, portable summer color spot on your deck or patio.

Onions belong to a genus (Allium) that includes familiar edibles like garlic, chives, shallots, and so much more. There are around 850 species of Alliums in the world, nearly all of them native to the Northern Hemisphere. Many have in common musky-smelling foliage and uniquely arranged flower heads that form globes or starburst patterns. Millenium was bred in 2000 (hence the name) by Mark “The Onion Man” McDonough of Pepperell, Massachusetts. McDonough is an architect by trade and an amateur gardener on the side with a passion for ornamental onions. Millenium is one of his finest introductions.

How to use in the landscape?

Ornamental onions have a bad rap because of a few thugs that seed around the garden and become a real nuisance. Millenium Ornamental Onion is a hybrid that sets no seed and behavesitself. The clump will slowly bulk up and may be divided in spring or fall to start a new patch, but it won’t venture out on its own.

Why Bower & Branch?

We believe in empowering homeowners with the truth about strong, healthy and structurally sound plants that are grown to perform in the ground after they leave the nursery for home delivery, always fresh inventory from the grower.

How To Plant

Plant Millenium Ornamental Onion in a site in all-day sun; afternoon shade may be a good idea in very hot climates. Millenium grows best in light (sandy), free-draining soils. It has average to low water needs, withstanding periods of drought once established. Most border situations suit it well, and it is at home in the rock garden, too. To use the flowers in arrangements, cut them as soon as they open, and they’ll last a long time in water. Diseases and insect pests are rarely a problem with this carefree Spirit; deer and rabbits avoid the aromatic foliage as well.

How To Water

Water twice weekly for the first 3-5 weeks; then water weekly for the remainder of the year until winter. When you water, water slowly and thoroughly. Watering needs may be altered due to extreme weather conditions.

How To Fertilize

Incorporate Elements Starter Plant food granular form into the soil when planting. If planting in spring or summer start fertilizing late fall using Elements Starter Plant food granular form on an annual basis each late year. Continue this for three years to get your plant well established.

How To Prune

Each fall, just before winter sets in clean up the previous years foliage and compost it. Be sure your perennials are mulched well for winter protection. Two inches of an organic mulch will do the job. Consider leaving the plant debris in place through the winter and doing your clean up on the weather warms in the spring. While it doesn't make things neat and tidy, the debris provides overwintering protection for insects, their eggs and pupae including our native Viceroy butterfly.
