Allium - Nigrum - Supports Overwintering Insects - Bulbs - Large Pack - 30 pcs

Allium Nigrum stands out each spring as creamy white blooms appear just as the garden comes to life. The rounded flower heads, made up of hundreds of small star-shaped flowers, offer a striking vertical accent among ornamental grasses or low-growing perennials. Supported by strong, upright stems and vibrant green foliage, this variety remains attractive for several weeks, making it a reliable choice for both borders and floral arrangements. Its longevity and distinctive structure bring a fresh, elegant look to planting schemes and vases alike.

Planting Time

For best results, plant Allium Nigrum bulbs in autumn, ideally from September to October. This timing allows the bulbs to establish healthy roots before winter, ensuring vigorous growth and robust flower heads the following spring. Proper timing is essential for achieving strong, decorative displays from these perennial bulbs.

Planting Depth

Bulbs should be planted at a depth of around 15 cm. This depth protects them from frost and provides the stability needed for tall, upright stems. Use well-drained, slightly moist soil to promote healthy development and minimise the risk of rot.

Spacing

Space the bulbs 15-20 cm apart. This allows each plant sufficient room to grow, ensuring impressive group displays and reducing the risk of fungal diseases. Adequate spacing also makes ongoing care and maintenance more straightforward.

Height

Allium Nigrum reaches a mature height of 60-70 cm. Its tall, straight stems showcase the creamy white flower heads above lower-growing plants, making it suitable for mixed borders, backgrounds, or as a central feature in planting schemes. The height also enhances its presence in cut flower arrangements.

Flowering Time

This variety blooms from May to June, providing an extended period of visual interest. The creamy white umbels with green centres retain their freshness for several weeks, adding a long-lasting decorative element to gardens and indoor displays.

Hardiness & Overwintering

Allium Nigrum bulbs are fully hardy and overwinter reliably in the ground. There is no need for lifting or special protection during colder months, making them a low-maintenance option for perennial garden bulbs.

Uses

Ideal for group plantings on lawns, among ornamental grasses, or with low perennials, Allium Nigrum enhances garden compositions with its elegant form and fresh colour. The flowers are particularly valued for their durability in vases, providing a lasting feature indoors. This variety supports garden biodiversity by attracting overwintering insects and offers a strong, visual accent season after season.
