Description

Growing up to 6', Asclepias exaltata is a tall species of milkweed with loose, spreading umbels of ivory to deep pink flowers and large tapering oblong leaves. Flower heads are reminiscent in form of exploding fireworks. Flowers give way to elongated seed pods.

Cultivation

Poke milkweed is a woodland native species, and one of the more shade tolerant Asclepias. It is easily grown in any moist rich soil in part shade or filtered light. The bloom period lasts about a month, during mid-summer. Zones 4-6

Propagation

Propagate from seed. Its deep taproot makes it near impossible to transplant successfully.

Additional Notes

The common name "poke milkweed" is due to the plant's leaves, which somewhat resemble those of pokeweed. All parts of the plant are considered poisonous in large quantities.
