Allium - Ostara - Retains Seedheads Through Winter - Bulbs - Large Pack - 10 pcs

Ostara ornamental alliums are valued for their rich purple flowerheads, which remain striking in the garden well beyond their flowering season. This variety is known for its compact, rounded blooms that stand out against glossy foliage, creating a balanced look in both borders and containers. With a height of 30-40 cm, Ostara alliums offer a unique blend of subtlety and presence. Their leaves retain their healthy appearance during flowering, setting them apart from many other garden bulbs. Ostara is an ideal choice for those who appreciate distinctive colours and reliable, easy-care perennial bulbs.

Planting Time

Plant Ostara allium bulbs from September to October. This timing allows the bulbs to establish strong roots and prepare for winter conditions.

Planting Depth

Set each bulb 10 cm deep in the soil. This depth provides effective insulation during cold periods and supports healthy growth.

Spacing

Leave 10-12 cm between bulbs. Proper spacing ensures the plants have room to develop and form their characteristic dense, spherical flowerheads.

Height

Ostara alliums reach 30-40 cm, making them suitable for the front of borders or mixed plantings with other perennials.

Flowering Time

These alliums bloom in May and June. Their vibrant purple flower spheres appear on sturdy stems, adding definition and colour to the garden at the height of spring.

Hardiness & Overwintering

Ostara is fully hardy and can remain in the ground throughout winter without the need for lifting. The bulbs reliably return each year, requiring minimal care.

Uses

This variety is well-suited to borders, rockeries, large pots, and planters. The flowers are long-lasting, making them excellent for fresh arrangements, while dried seedheads provide attractive accents in dried displays. The striking purple colour and glossy foliage make Ostara a favourite among gardeners seeking low-maintenance and original bulbs for gardens.
