Allium - Firmament - Masses of Soft Pastel Blooms - Bulbs - Large Pack - 10 pcs

Allium 'Firmament' stands out each spring with its striking, spherical heads of soft purple blooms rising above fresh green foliage. The subtle, slightly spicy scent adds a gentle note to the garden, while the vivid colour and height of these ornamental onions create a distinct focal point. Their reliable flowering and upright form make them a favourite among those seeking durable, low-maintenance flower bulbs that bring structure and interest to mixed borders.

Planting Time

For best results, plant Allium 'Firmament' bulbs in autumn, from September to October. This timing allows the bulbs to establish strong roots before winter, supporting healthy growth and flowering the following spring. Choose a sunny position to ensure robust development and vibrant blooms.

Planting Depth

Set the bulbs at a depth of 8-10 cm in well-drained, fertile soil. A slightly sandy or loamy mix is ideal, as it helps prevent excess moisture around the bulbs and encourages steady root growth. Planting at this depth offers effective protection against frost and supports healthy, upright stems.

Spacing

Allow 10-15 cm between each bulb to give the plants enough space to grow without competing for nutrients. Proper spacing makes routine care and watering easier, while also encouraging strong, even development across the group.

Height

Allium 'Firmament' reaches up to 80 cm, with slender, stable stems topped by large, rounded clusters of purple flowers. The impressive height makes these perennial bulbs suitable for adding vertical interest to beds, borders, and among ornamental grasses, with stems that withstand spring breezes well.

Flowering Time

Flowering takes place in April and May, as gardens begin to reawaken after winter. The large, semi-spherical blooms, measuring up to 12 cm across, fill the gap between tulip displays and the start of the summer perennial season, providing lasting colour and visual impact at a key time of year.

Hardiness & Overwintering

These garden bulbs are fully frost hardy and do not require lifting for winter. Once planted, the bulbs can remain in the ground all year, returning reliably each spring without special care.

Uses

Allium 'Firmament' is suitable for flower beds, mixed borders, rockeries, and as cut flowers. The decorative blooms not only enhance planting schemes but also help deter common garden pests. With modest cultivation requirements, these bulbs for gardens are well suited to both new and experienced gardeners, and are regularly noted in trusted reviews for their resilience and consistent flowering.
