Allium - Ostara - Elegant Whorled Inflorescences - Bulbs - Giga Pack - 50 pcs

Allium Ostara brings a striking touch to garden borders, rockeries and large containers with its rounded clusters of deep purple blooms. This distinctive variety combines the attractive qualities of Karataviense and Purple Allium, offering long-lasting foliage that stays fresh throughout the flowering period. Its upright stems and robust flower heads add structure to planting schemes, making Ostara a standout choice for gardeners looking to enhance spring displays with reliable garden bulbs.

Planting Time

Plant Ostara Allium bulbs in autumn, ideally from September to October. This timing allows the bulbs to establish roots before winter, supporting healthy growth and abundant flowering the following spring.

Planting Depth

Set each bulb at a depth of around 10 cm. This depth provides stability, encourages strong root development, and helps protect bulbs from frost during colder months.

Spacing

Space bulbs 10-12 cm apart to give each plant room to develop fully. Proper spacing supports airflow, makes maintenance easier and highlights the decorative qualities of the blooms.

Height

Allium Ostara reaches a height of 30-40 cm. The sturdy, tubular stems hold the spherical flower heads above surrounding plants, bringing vertical interest to beds and containers.

Flowering Time

Ostara Allium blooms from May to June, adding a vivid purple accent to the garden at the height of spring. The flowers remain fresh for an extended period, pairing well with other perennial bulbs for dynamic seasonal displays.

Hardiness & Overwintering

This variety is fully frost hardy and can remain in the ground year-round. There is no need to lift the bulbs after flowering, which makes Allium Ostara a practical option for low-maintenance gardening with perennial bulbs.

Uses

Ostara is well suited to mixed borders, rock gardens and larger planters. Its bold, spherical flowers combine effectively with a range of other plants and also perform well as cut flowers or in dried arrangements, retaining their decorative appeal after drying.
