Create long-lasting and beautiful floral displays with a pack of 20 Allium ‘Unifolium’ bulbs, also known as the 'American Onion'. Producing clusters of beautiful bell-shaped pink, purple flowers, these blooms will last a little longer than other varieties.
The delightful flowers grow above green basal leaves and as the foliage matures, it changes to a grey green which is a wonderful combination of colours. They are a great way to attract bees and butterflies into your garden and have been added to the Royal Horticultural Society Plants for Pollinators collection.
In addition to its delightful flowers and foliage, this easy to grow allium has been given the prestigious Award of Garden Merit from the Royal Horticultural Society. This is given to plants that, following rigorous trials, have show suitability to the UK climate, have good resistance to pests and diseases and have consistent growth.
Plant these wonderful alliums in the edge of a border, in pots and containers or enjoy its wonderful floral display in cut flower displays around the home.
To get the best from the Allium ‘Unifolium’ bulbs, position them in a bright and sunny spot, in any moist but free draining soil.
