Here I am offering Seeds of Oxypetalum caeruleum, also known as Blue milkweed Vine, tweedia, and southern star. It is a very desirable plant because of its blossoms that start out in late Spring as a clear pale blue star that slowly develops into violet in late Summer and purple in early Fall. This evergreen perennial has beautiful heart shaped leaves and the blooms work well as a long lasting cut flower. This plant likes to live in full sun with a well draining soil. This is a larval host plant for the Monarch butterfly, and it is a nectar source not only for the Monarch but also for countless other butterflies. This plant can be grown as an Annual so it will go to seed in one season, or it can be grown longer in USDA Hardiness Zones 8 to 10
