Asclepias – Silky Mix

One of over two hundred varieties of Asclepias, ‘Silky Mix’ stands out for its beautiful alternating deep red and gold colored blooms. Blooming mid Summer through early Fall, ‘Silky’, like most Asclepias prefers sunny, dry locations and does well in substandard soil. A tender perennial in some zones and annual in others, ‘Silky Mix’ is a beautiful addition to any garden or patio and will attract many different types of butterflies and other pollinators. Also known as “butterfly weed” because of its propensity for hosting the colorful insects, ‘Silky Mix’ makes a beautiful border or walkway plant but will also do well in a deep pot or container.

We got this plant from the Annie’s Annual section of Yamagami Nursery in Cupertino CA.

Known to have some medicinal value as a cough expectorant, the plant’s milky white sap can also cause irritation if it comes into contact with your eyes. Asclepias contain cardiac glycosides that are poisonous to humans, but they pose the most danger to grazing animals.

Asclepias need cold weather to prepare the plant for high yields of flowers, so first year plants may not perform well or bloom as vigorously without exposure to the cold.
