Allium 'Millenium' is a fantastic ornamental onion that is earned its place as a garden staple. It was even the 2018 Perennial Plant of the Year! Here is why it is so beloved:
Attractive Features:
- Vibrant Blooms: 'Millenium' produces beautiful, rosy-lavender spherical flower heads that are packed with numerous tiny florets. These blooms appear in mid to late summer, providing a burst of color when many other plants are starting to fade.
- Upright and Sturdy: The flower heads are held on strong, upright stems that rise above the foliage. This gives the plant a neat and tidy appearance, and it also makes the flowers excellent for cutting.
- Clump-forming Growth: Unlike some alliums that spread aggressively, 'Millenium' is a clump-former. It gradually expands to form a nice-sized clump, but it will not take over your garden.
- Attractive Foliage: The plant features attractive, deep green, grass-like foliage that adds interest even when it is not in bloom.
Growing Conditions:
- Sun to Partial Shade: 'Millenium' thrives in full sun to partial shade. It prefers at least 6 hours of sunlight per day for best flowering.
- Well-Drained Soil: It is crucial to plant it in well-drained soil. Soggy soil can lead to bulb rot.
- Adaptable: It can tolerate a variety of soil types, including clay, sandy, and loamy soils, as long as they are well-drained.
- Drought-Tolerant: Once established, 'Millenium' is quite drought-tolerant, making it a great choice for dry gardens or areas with limited watering.
Care and Maintenance:
- Low Maintenance: 'Millenium' is a very low-maintenance plant. Once established, it requires minimal care.
- Watering: Water regularly during the first year to help it establish its roots. After that, it can tolerate dry periods.
- Fertilizing: Generally, it does not require regular fertilization, but a light feeding in spring can be beneficial.
- Deadheading: You can remove spent flower heads to prevent self-seeding and maintain a tidy appearance.
Uses in the Garden:
- Borders and Edging: Its upright habit and vibrant blooms make it perfect for adding vertical interest to borders or edging pathways.
- Mass Plantings: Planted in mass, it creates a stunning display of color and texture.
- Mixed Borders: It adds a unique touch to mixed borders with other perennials and shrubs.
- Containers: It can also be grown in containers, adding a pop of color to patios or balconies.
- Cut Flowers: The flowers are long-lasting and make excellent cut flowers.
Benefits:
- Attracts Pollinators: The flowers are highly attractive to bees and butterflies, making it a valuable addition to pollinator gardens.
- Deer and Rabbit Resistant: Deer and rabbits tend to avoid alliums, so it is a good choice for gardens where these animals are a problem.
- Low-Maintenance: Its drought tolerance and minimal care requirements make it an ideal plant for busy gardeners.
- Long Blooming Period: 'Millenium' provides a long-lasting show of color in the garden.
If you are looking for a beautiful, low-maintenance, and pollinator-friendly plant to add to your garden, Allium 'Millenium' is an excellent choice! Its vibrant blooms, attractive foliage, and deer resistance make it a valuable addition to any landscape.

Other Details
The most important part of the plant is its root system. Healthy roots are the foundation of a healthy, vibrant plant. The type of plug container used is based on the specific needs of the plants. Perennials offered as bare root traditionally perform better when planted as bare root.Planted in a specialized mix, potted plants have well established root systems. Top growth stage will vary depending on the current life cycle and time of year when shipped. In Winter and early Spring dormant plants may be shipped. Dormant plants may be planted right away, even before the last frost date.
Most bare root varieties are field grown for at least one season, though Hemerocallis and Hosta are grown for two seasons. The bulk of the soil is removed during the harvesting process and the tops of most varieties are trimmed back to the crown. They are graded, packed in shredded aspen or sphagnum moss and stored in freezers until ready to be shipped.

Plant information and care is provided in the Overview section, Plant Genus Page and general information is provided in the Planting Care & Guides. Additional questions can be asked on each Plant page.
Plant Spacing: Using the maximum mature spread or width of a plant to guide spacing, ensures space to grow to full size. To fill an area sooner, plant them closer together. Just remember, future thinning or transplanting may be needed.
Water: Keep a close eye on newly planted perennials, especially throughout the first growing year. Most early plant loss is due to too much or too little water!
