Spider Flowering Plant Seeds
Spider Flower (Cleome hassleriana) is a dramatic warm‑season annual known for its tall airy flower clusters, long spider‑like stamens, and bold summer height. Blooming in shades of pink, lavender, rose, white, and bicolors, Cleome creates a striking vertical accent in borders, cottage gardens, and pollinator landscapes.
What is Spider Flower?
A vigorous annual frequently highlighted in gardening guides for its height, fragrance, and ability to attract pollinators. Spider Flower thrives in heat, tolerates drought once established, and produces continuous blooms from early summer until frost.
Why gardeners choose it:
• Tall, dramatic flower clusters
• Long stamens create a “spider-like” appearance

• Attracts bees, butterflies, and hummingbirds
• Thrives in heat and summer sun
• Lightly self‑sows for naturalized drifts

Planting Instructions:
• Direct‑sow Cleome seeds outdoors after frost or start indoors 4–6 weeks early.
• Cover seeds lightly (1/8 inch).
• Germination occurs in 7–21 days depending on temperature.
• Provide full sun and well‑drained soil.
• Space plants 12–18 inches apart for tall, airy growth.
