Allium - Globemaster - Large, Upright Flower Spikes - Bulb - 1 pc

Allium 'Globemaster' stands out for its combination of striking height and bold, spherical flower heads. Its vivid purple blooms and robust stems make it a practical choice for those seeking a prominent architectural feature in the garden. This variety is valued not only for its decorative appeal but also for its adaptability and reliable performance in a range of garden settings, from formal borders to contemporary plantings.

Planting Time

For best results, plant Allium 'Globemaster' bulbs in autumn, ideally between September and October. This timing allows the bulbs to establish roots while the soil is still warm, supporting healthy growth in the following season. Early planting also helps perennial bulbs like this one to withstand winter conditions more effectively.

Planting Depth

Set each bulb at a depth of approximately 10 cm. Planting at this depth provides stability for the tall stems and helps protect the bulb from frost. Ensure the soil is well-drained and slightly moist during planting to encourage strong root development.

Spacing

Allow 20-25 cm between bulbs when planting. Adequate spacing is important for airflow and light, supporting vigorous growth and allowing each flower head to reach its full size. This also helps to minimise the risk of disease and ensures a balanced display when the plants mature.

Height

Allium 'Globemaster' reaches a mature height of 80-100 cm. Its tall, upright stems provide a vertical accent, with dense, globe-shaped clusters of purple flowers held well above the foliage. This makes it a strong focal point, whether planted singly or in groups among other garden bulbs.

Flowering Time

This variety blooms in June, producing large, compact heads composed of many small, star-shaped purple flowers. The blooms remain attractive for several weeks, extending the period of interest at the start of summer and providing colour when many spring bulbs have faded.

Hardiness & Overwintering

Allium 'Globemaster' bulbs are fully hardy and can remain in the ground throughout winter. They tolerate low temperatures without the need for lifting or extra protection, making them suitable for both experienced gardeners and those new to planting bulbs.

Uses

Ideal for perennial borders, mixed beds, and modern garden designs, Allium 'Globemaster' pairs well with other ornamental plants. Its tall purple blooms are also suitable for cutting and use in fresh arrangements. In addition, the plant naturally deters some garden pests, offering a practical benefit alongside its decorative qualities.
