Asclepias tuberosa


With its striking bright orange flowers, this North American and Mid-Atlantic native is a great accent plant. It is a host plant for monarch butterfly larva and helps increase the biodiversity on a green roof.

Like most perennials, this plant will benefit from growing in a deeper soil profile, or, where the green roof media has been mounded. It will need regular water to become established. A wonderful accent plant, this species will add height and color to the green roof plant palette.
