Allium ‘Millenium’ is a late-flowering ornamental onion that steals the show just as other alliums have finished blooming. From July to September, it produces a wealth of vibrant purple flower heads that bring colour and life to the summer garden.

The plant forms neat, compact clumps of fresh green, grass-like foliage and is perfectly suited for borders or containers.

Late summer flowering
While most alliums bloom in spring, Allium ‘Millenium’ offers a second burst of colour and energy later in the season.
Distinctive flower shape
Its round, purple flower heads stand gracefully above the foliage – striking yet refined.
Low maintenance
This hardy perennial requires little care, is winter-hardy, and reliably returns year after year.
Bee-friendly
A true favourite among bees and bumblebees, thanks to its nectar- and pollen-rich blooms.

Light
Plant in a sunny spot for the best flowering. In partial shade, the display will be less abundant.

Soil
Well-drained soil is essential – preferably dry to moderately moist. Avoid heavy, waterlogged soil, as bulbs may rot.

Watering
Water sparingly. Only give extra water during prolonged dry spells.

Pruning
Cut back spent flower stems to keep the plant tidy. Allow the foliage to die back naturally so the bulb can store nutrients for next year’s growth.
