Product Information

Full details

The Allium Cowanii, also known as Allium Neapolitanum, is a delicate, star-shaped flowering bulb perfect for gardeners looking to add a touch of white elegance to beds, borders, and containers. These bulbs provide a natural, airy aesthetic that thrives when planted in groups, offering a magnet for pollinators like bees and butterflies throughout the late spring. While these bulbs are remarkably low-maintenance and UK hardy, they require well-draining soil to prevent rot, making them unsuitable for heavy, waterlogged ground.
