Señorita Blanca arrived as an answer to gardeners who loved the drama of cleome but not its habits. The thorns are gone. The sticky glandular foliage is gone. The musky odor is gone. The aggressive self-seeding that could turn a single plant into a colony is gone, replaced by sterility that keeps it tidy but means it can only be grown from transplants each season. What remains is a compact, upright plant that matures to 2 to 4 feet with dark green foliage and silvery-white flowers that open from June through the first frost.

It grows easily in average to dry, well-drained soil and blooms best in full sun, though it tolerates light shade. Consistent watering through the season builds the plant up; once established it handles heat and drought without wilting or dropping flowers. The stems are on the weak side, so planting lower-growing companions nearby provides practical support while filling the gap between cleome's bare lower stems and the ground. Because it doesn't set seed, deadheading is optional — a matter of tidiness rather than necessity.
