Allium 'Sphaerocephalon' Drumstick
A late-summer marvel, the Drumstick Allium is a master of transformation. It begins as a slender green bud, slowly developing its signature oval head that transitions from green to a rich burgundy-claret, starting from the top down. Planted in generous drifts, these tightly packed, egg-shaped blooms sway on wiry stems, creating a mesmerizing, rhythmic dance in the breeze. They are perfect for weaving through perennial borders, adding a pop of deep, jewel-toned colour and dynamic texture long after other flowers have faded. Their slender profile allows them to mingle effortlessly without overcrowding neighbors, making them an exceptional choice for naturalistic and prairie-style plantings, bringing your garden composition to a beautiful crescendo.
