Milkweed/Pleurisy Root – Salt Spring Seeds

Asclepias tuberosa

A beautiful hardy herbaceous perennial, growing up to 3 feet tall, with tresses of bright orange-red flowers blooming from early summer to early autumn. It attracts many butterflies, including Monarchs, abundant bees, and other pollinators.

The seed is a cold-soil germinator. If not being sown in the early spring, then it is recommended to pre-treat the seeds in the refrigerator (not the freezer) for 2-3 weeks before sowing warm. Germination is relatively fast and moderate.
Plants prefer regularly watered sand or gravel soils (i.e. well drained), with full sun, although they can grow in light woodland/semi-shaded areas.

Plants are best spaced at least 2 feet apart.
