Ornamental onions like Millenium Allium are power performers in the garden. This variety has the pretty purple globe-like flower of alliums above clumps of slender green leaves. The result is a rush of fragrant, round flower clusters just above a pretty green clump. Both the leaves and flowers of Millenium Allium have a sweet fragrance. And this little onion hybrid has long-lasting blooms in a drought-tolerant plant.
Millenium Allium blooms appear in summer, a little later than some Allium varieties. They grow in nearly any type of soil and attract bees and butterflies to the rounded flower clusters. Deer and rabbits tend to avoid allium plants. At a height of nearly 20 inches and 15 inches wide, this little allium is a great thriller in garden containers or a nice garden bed border. The flowers are perfect for a round, interesting bloom in flower arrangements.
Millenium Allium Care
Plant Millenium Allium in a garden spot or container that gets at least some sun – 4 hours a day or more. You can place it in a container with potting mix or in poor or clay soil. This allium hybrid will adapt to any soil conditions and typically is free of plant disease. It grows as a perennial in zones 4 through 8. Just cut some of the flowers for fresh or dried arrangements; the allium does not need dividing.
Millenium Allium Spacing
For a mass planting of purple globe-shaped flowers, plant several Millenium Allium plants together. Or make a border of the fragrant summer bloomers. Space the plants about 10 to 14 inches apart from center to center.

Plant Addicts Warranty - 1 Year (Extra Purchase Required)
We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die. Hungry animals, drought, poor soil conditions, over watering, diseases & pests are all good examples of what can cause plants to die. The Plant Addicts Warranty is a 1 year warranty protecting you from all of the unknowns and will replace your plant if something were to happen to it.
The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability). We may ask for photos for documentation purposes, but we try to make the process as easy as possible.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
