Allium Cowanii - Prolific Summer Blooms - Bulbs - Large Pack - 200 pcs

The refined white blooms of Allium Cowanii bring a sense of lightness and subtle structure to any planting scheme. Each slender stem is topped with a crisp, snow-white flower head, providing a clean accent for borders, low beds, and container displays. The understated elegance of Cowanii complements both modern and traditional designs, and its neutral tone enhances mixed bulb plantings. The presence of these white flowers creates a balanced interplay of light and shadow, adding a fresh, harmonious note to garden spaces.

Planting Time

Allium Cowanii bulbs are best planted from September to the end of October. This period allows the bulbs to establish strong roots before winter, ensuring healthy growth and abundant flowering in spring.

Planting Depth

Set the bulbs at a depth of 6-8 cm in well-drained soil. This depth provides protection against frost while supporting reliable root development for the new season.

Spacing

Allow 10 cm between each bulb when planting. Adequate spacing encourages healthy growth and helps prevent disease, while also giving the flower heads room to stand out in group plantings.

Height

Allium Cowanii reaches a height of 25-30 cm. Its compact stature makes it suitable for edging, low beds, and group displays, as well as for planting in containers on terraces and balconies. The manageable height ensures easy pairing with other garden bulbs.

Flowering Time

Flowering occurs in May and June, offering a fresh burst of white blooms at the start of the summer season. The clear contrast between the white flowers and green foliage provides a striking visual effect when many other plants are just beginning to develop.

Hardiness & Overwintering

Allium Cowanii bulbs are fully hardy and overwinter well in the ground. Once planted at the correct depth, they do not require lifting for winter and will withstand cold conditions without difficulty.

Uses

The pure white flowers are well-suited to naturalistic borders, rockeries, and mixed bulb displays. Cowanii works effectively in group plantings or combined with other perennial bulbs for harmonious, multi-coloured arrangements. It also performs well in pots and retains freshness as a cut flower for indoor use.
