'Millennium' Ornamental Garlic

Here is the English translation with the product name and Latin name bolded at the beginning:

Ornamental Onion ‘Millenium’ (Allium ‘Millenium’) is a compact bulbous perennial that forms a dense clump of dark green, strap-like foliage that remains decorative throughout the growing season. From July to August, its upright stems carry charming spherical clusters of bright purple flowers, adding colour and structure to flower beds when many other perennials begin to slow down. Reaching 40 to 50 cm in height, this variety is equally well suited to small spaces and larger plantings. Hardy to Zone 5, it stands out for its late flowering period, tidy habit, and excellent drought tolerance once well established.

Plant the bulbs in fall at a depth of approximately 8 cm, spacing them 15 to 20 cm apart. Choose a location in full sun with light, poor to moderately fertile, and perfectly drained soil with a neutral to slightly alkaline pH. Water after planting, then moderately during active growth, allowing the soil to dry slightly between waterings. A light application of compost in spring is generally sufficient, as excessive fertilization encourages foliage growth at the expense of flowers. After flowering, allow the foliage to dry naturally before cutting it back so the bulbs can replenish their reserves.

Ornamental Onion ‘Millenium’ is perfect for perennial beds, borders, rock gardens, pollinator gardens, and well-drained containers. Its compact habit pairs especially well with coneflowers, sage, lavender, catmint, and ornamental grasses, which thrive in the same sunny conditions. Its nectar-rich flowers attract bees, butterflies, and many other beneficial insects, extending the food resources available in the garden in late summer. The flower clusters are also beautiful in fresh or dried arrangements, where they retain their shape and elegance for a long time.
