Allium Bulbs

Alliums are excellent for bridging the gap between spring-flowering bulbs and summer-flowering perennials. Their neat flower heads lend a unique architectural touch to borders and patio containers. Plant Allium bulbs in clumps or in drifts amongst other plants, leaving the seed heads intact for an architectural autumn display. Make the most of your Allium plants with our guide to planting bulbs and view our informative video.
