Asclepias angustifolia is a truly superb garden plant, that is virtually unknown outside its native range in southern Arizona and adjacent Mexico, where it can be found between 4,000' and 7,000' elevation. Narrow-leaf milkweed forms a tight clump of upright stalks that create a 2' tall x 2' wide garden specimen. The stalks are clothed with amsonia-like foliage, and topped from May through September (NC) with terminal clusters of flowers that emerge as blush pink buds opening white. After one flush of flowers is complete another flush starts, and this continues throughout the spring and summer. Our offering is a seed strain from a Patrick McMillan collection in Santa Cruz County, Arizona. Disclaimer: Monarch butterflies are not shipped with the plants...they will be flying in on their own in summer.
