The Spider Flower Mix, a stunning blend of pink, purple, and white Cleome, or spider flowers, has been cherished since the 1800s for its unique, elongated blooms that resemble long, thread-like clusters and seedpods, earning its name. Standing tall at 36-42 inches, and capable of reaching heights up to 6 feet with an equal width, this fast-growing variety is both sturdy and self-supporting, making it a stately presence in the garden. Loved by butterflies, hummingbirds, and other pollinators, the Spider Flower thrives from early summer until the first frost, offering airy blossoms in a mix of rose, pink, purple, and white. Introduced from the West Indies to England in 1817, it features moderately thorny stems and intriguing 4-5" seedpods that resemble spider legs, adding to its allure. This easy-to-maintain plant requires ample space to flourish, bringing a striking visual appeal to any garden setting.
