Giant alliums, such as Allium 'Globemaster,' make a striking statement with their massive, softball-sized flower heads perched atop sturdy stems reaching 3 to 5 feet tall. Blooming in late spring to early summer, they bridge the seasonal gap between spring bulbs and summer perennials, adding architectural height and bold color to borders and mixed plantings.
Their dense clusters of star-shaped florets form perfect spheres in shades of purple, lavender, and white, attracting bees, butterflies, and admiration alike. Low-maintenance and deer-resistant, these dramatic blooms offer effortless beauty year after year.
