Cleome hassleriana

Cleome hassleriana, also known as ‘spider flower’, belongs to the Cleomaceae family and is recognized for its tall, airy habit and distinctive spidery blooms that add dramatic vertical interest to landscapes. This heat- and drought-tolerant annual thrives in full sun, well-drained soil, and moderate fertility. Cleome is ideal for mass plantings, cottage-style gardens, and background accents where bold color and structure are desired throughout the summer.
Spray adjuvant at sticking, remove from mist quickly, and keep soil evenly moist. Maintain pH 5.6–6.2, EC 0.8-0.9, feed 50 ppm N then 100–150 ppm N. Apply fungicide at sticking and week 2; Daminozide 1,500–2,500 ppm in week 4. Pinch at transplant.
