Allium giganteum, it won't surprise you to read, is probably the tallest flowering in the allium family. Giganteum is a sight to behold, adding height and wonder to the border. Quite frankly, attention seeking herbaceous perennial is worthy of all the attention it attracts.
Flower heads appear in May and June and reach up to 16cm, adorning the top of stems that tower as much as 1.5m above the ground. The added bonus of Alliums are the seed heads left behind until Autumn once the petals are gone, drama in your own back yard!
A dramatic back drop or centre piece of your border, it is not just you who will enjoy this beauty, giganteums will attract butterflies to your garden.
Alliums are easy to grow, they don't like being waterlogged so adding grit to the soil as you plant them will reap rewards.
