Allium - Ostara - Tolerates Exposed Coastal Sites - Bulbs - Giga Pack - 50 pcs

Allium Ostara stands out for its striking, spherical purple blooms and straightforward cultivation, making it a reliable choice for both borders and large containers. Each bulb has the potential to produce several flower heads, creating a vivid display with minimal effort. With a mature height of 50-60 cm, this perennial bulb is well suited to mixed plantings, providing structure and colour even in exposed or coastal locations.

Planting Time

Plant Allium Ostara bulbs in autumn, ideally from September to October. This timing allows the bulbs to establish strong roots before winter and ensures a robust flowering period in late spring.

Planting Depth

Set bulbs 10-15 cm deep in well-drained soil. Planting at this depth helps protect the bulbs from frost and supports healthy root growth.

Spacing

Allow 10-20 cm between each bulb. This spacing gives each plant enough room to develop fully, resulting in impressive group displays of purple flower heads.

Height

Mature plants reach 50-60 cm, making them suitable for combining with both lower perennials and taller species in garden beds.

Flowering Time

Allium Ostara flowers from May to June, providing a burst of colour just as most spring flowers are fading. This extends the season of interest in the garden for several weeks.

Hardiness & Overwintering

These garden bulbs are fully frost hardy and can remain in the ground over winter without protection. Removing spent flower heads after blooming helps the bulbs conserve energy for the next season.

Uses

Ideal for traditional beds, modern garden schemes, containers, and flower borders, Allium Ostara is valued for its vivid purple blooms and reliable performance. The flowers are also suitable for cutting and display in vases. This variety is often chosen by gardeners seeking perennial bulbs that combine striking appearance with low maintenance requirements.
