Allium
Ornamental Onion
Our selections are embellished versions of the common culinary bulbs. Prospering in a sunny well-drained site, these pest-resistant Alliums add flair to the garden, your favorite container and a fresh or dried arrangement.
We have Jan Bijl to thank for this dazzling 1971 cross between Allium christophii and Allium macleanii. Hoisted upon staunch 2 ½ ft. tall, smooth green stalks, the gigantic densely packed orbs occasionally exceed 11 in. across, fostering a long-lasting flourish of countless star-shaped purple florets that glisten with a silver-laced metallic sheen. Adored by bees, florists and plant aficionados, ‘Globemaster’s otherworldly blooms work well when planted amid perennials such as Verbascum nigrum ‘Album’ and Alchemilla ‘Robusta’, so its strapping gray-green leaves will be hidden once they decline.
