Growing Zones and Care Tips:

1. Growing Zones: Millenium Allium is well-suited for USDA Hardiness Zones 4-9. It can adapt to a range of climates but performs best in regions with cold winters and mild summers.

2. Sunlight: To ensure optimal growth and bloom, plant your Millenium Allium in full sun. This perennial craves at least 6 hours of direct sunlight daily.

3. Soil: Well-draining soil is key for the Allium's success. Loamy soil enriched with organic matter is ideal. Avoid waterlogged or compacted soils, as they can lead to root rot.

4. Watering: Water your Millenium Allium moderately, keeping the soil consistently moist but not soggy, especially during the growing season. In the dormant winter period, reduce watering.

5. Fertilizing: Apply a balanced, all-purpose fertilizer in the spring to encourage robust growth and profuse flowering.

6. Pruning: After the flowers fade, trim the spent blooms to maintain a neat appearance. Leave the foliage in place until it turns brown, as it provides nutrients for the bulb's future growth.

7. Pests and Diseases: The Millenium Allium is generally resistant to most pests and diseases, making it a worry-free addition to your garden.
