Tropical milkweed (Asclepias curassavica) produces clusters of bright blooms from midsummer to frost atop plants that reach 3 to 4 feet tall: great for height and color–and butterflies!–in a bed, border, or container. Speaking of butterflies: I grow at least five kinds of milkweed here at Hayefield, and the tropical milkweed always hosts more monarch larvae than any others (Asclepias incarnata usually comes in second). The flowers of the species are orange-and-yellow, but ‘Silky Gold’ (from which I collected these seeds) is solid yellow. Full sun. Can be grown as an annual anywhere; may be perennial in Zones 8 to 10.
Collected in September 2020. At least 15 seeds.
