Key Attributes
About Red Butterfly, Milkweed Seed
Red Butterfly Milkweed (Asclepias curassavica) bears clusters of bright red flowers with golden-yellow crowns from midsummer until frost. This vigorous tropical milkweed often blooms in its first year from seed, giving butterflies, bees and hummingbirds a quick source of nectar. Its leaves also serve as a food source for monarch caterpillars. Plants reach about 3 feet tall and thrive in full sun with moist, well-drained soil. Grow it as a tender perennial in Zones 8-11 or as a colorful warm-season annual where winters freeze.

Tips
Pests & Diseases
Leaf spots, rust, powdery mildew, and root rot may occur. Provide airflow, avoid waterlogged soil, remove badly affected foliage, and clean tools between plants; discard material showing severe disease rather than composting it.
Aphids, milkweed bugs, spider mites, and oleander aphids may gather on stems and pods. Identify monarch eggs and caterpillars before acting, rinse or hand-remove pests when practical, and avoid systemic or broad-spectrum insecticides.
