Description
Perk up your early summer style with these fabulous, architectural jewels. Bobbing beautifully throughout planting schemes with ball-like flowerheads, Allium 'Ostara' make a brazen statement with a cool defined shape along with an intense burgundy hit of colour. These densely-packed flower globes are full of nectar, making them an excellent choice for the wildlife-conscious gardener. Totally versatile, trendy alliums can look both wacky and whimsical, depending on your garden design. Plant Allium 'Ostara' in modern, chunky groups, or create a mixed country palette with an informal smattering – either way, they’ll be just what’s needed to carry the momentum from spring through to early summer.
If you enjoy displaying cut flowers in your home, you’ll love having a good supply of these stocky alliums to hand. Flowering on a sturdy, compact stem, Allium 'Ostara' are tall enough to make a big impact but robust and powerful enough to be strong and long lasting in a vase too. Plus, you won’t need many to make something truly spectacular either – just a few stems provides a healthy dose of flower power in each arrangement!
