Allium: cultivation of hardy ornamental onions, some of the biggest flowers for the garden

The most popular species and varieties are fully hardy in the UK, and the huge flowerheads are very long lived as cut flowers when fresh, and even more long lived after the flowers fade and the developing seed capsules remain attached to the flowerheads, keeping the ornamental value for months after the end of the blooming season and therefore very useful in dry flowers arrangements. Perfect for pollinators and available in a wide range of colors and sizes, you will find at least one to match in the planting scheme of your garden, especially if you are looking for a vertical focal point in your border. Full sun and well drained soil will make this plants very happy in your garden
