Designer Allium Garden Collection - Pre-Order

Flower bulbs
In stock

Quick overview

Alliums are a designer’s favourite! When spring daffodils and tulips have flowered, it is the turn of ornamental onions. Alliums take us into summer with high impact and structural form in the garden.  The glorious pompom flowers on tall erect stems create a great eye catching display for all to enjoy. After flowering the seed heads become a stunning architectural feature too. Enjoy these Alliums for planting in Autumn.
