Description
The giant round purple flower globes of this magnificent allium are the perfect way to introduce colour and structure to your garden between spring and summer, and when it comes to ornamental alliums, Allium 'Globemaster' truly is one of the best! The fact Allium 'Globemaster' won a prestigious RHS Award of Garden Merit means you can rely on it giving you a spectacular, colourful display without fuss. These towering alliums reach a height of nearly 1m and have good, strong stems to support the large ball-like blooms – they’ll also attract a frenzy of bees and butterflies.
Whether you have a modern and contemporary style or a cute cottage garden, Allium 'Globemaster' will fit right in and partner happily with virtually any other plant. Plant generous swathes of them running through borders or shrubberies and not only can you enjoy their wonderful bobbing flowers in the garden, but you can use them as cut flowers too.
The blooms of Allium 'Globemaster' make a bold statement in any indoor arrangement and have a great vase life too. They look really trendy in a tall glass vase, and equally as good in an informal mixed bunch.
