5 Seeds Calotropis gigantea Crown Flower Giant Milkweed Ornamental Shrub

Calotropis gigantea, commonly called crown flower or giant milkweed, is a tropical shrub grown for its large clusters of waxy blossoms and its bold, silvery-green foliage. The plant forms an upright, spreading habit and brings a sculptural, exotic look to warm-climate gardens and containers. Its thick, felted leaves and rounded flower clusters make it a striking ornamental feature where temperatures allow year-round growth.

Grown as an ornamental shrub for borders, mixed beds, and large patio containers in frost-free regions, or as an annual or overwintered container plant in cooler zones. The flowers are long-lasting and suit cut arrangements, while the substantial foliage adds texture and contrast. Plants grow vigorously in heat and full sun and prefer well-drained soil with moderate water once established.
