'Globemaster' Ornamental Onion Bulb
Best statement flower for gardeners seeking low-maintenance, pollinator-friendly spring color.
The 'Globemaster' Ornamental Onion is the star of any spring bulb garden, producing massive, 8-inch, soccer-ball-sized bloomheads in a striking lavender-pink hue. These impressive flowers appear late in the season, perfectly bridging the gap between spring and the glory of summer. The blooms rise on sturdy stems reaching up to 3 feet tall. While not strongly scented, this sterile Dutch hybrid attracts beneficial pollinators like bees and butterflies. After blooming for nearly three weeks, the flower heads dry beautifully on the plant, making them excellent for use as long-lasting indoor arrangements. This variety reliably returns year after year, focusing its energy on producing spectacular flowers.
