Allium 'Summer Drummer'
As one of the tallest and latest-blooming alliums, 'Summer Drummer' provides a spectacular grand finale to the season. Its sturdy, towering stems can reach impressive heights, each topped with a large, dense globe composed of countless tiny, star-shaped florets. The flowers are a beautiful mix of deep purple and crisp white, creating a frosted, shimmering effect from a distance that catches the late summer light. Their sheer size and architectural stature make them an unmissable focal point in the back of the border, standing tall and proud like sentinels in the garden. The substantial globes retain their shape long after the colour fades, providing striking structural interest that carries the garden's form well into autumn, looking magnificent when touched by frost.
