True-blue flowers are rare and these aquamarine gems will sparkle in the garden. Flower buds and older flowers are lavender, adding extra flair. Blue milkweed, also known as star of Argentine and southern star, draws in pollinators to its sweetly scented flowers, but unlike other milkweeds, it is not considered critical for monarch caterpillars. This cutting flower adds the perfect "something blue" to floral arrangements. Perennial in USDA zones 10–11; otherwise grown as an annual. In areas where perennial plants are vining shrubs, they may reach 10' over time. Sap is toxic; avoid eye/skin contact and do not ingest. Deer resistant.
