GREEN MILKWEED ,flowers SEEDS
flowers. It prefers medium-wet through dry soil conditions and grows best in full sun to partial shade. Like most Milkweeds, it blooms mid-summer: June, July, and August. Tall Green Milkweed is attractive to butterflies and bees. Bee visitors include honeybees, bumblebees, and leaf-cutting bees.
Description: This perennial wildflower is 1Â½â3' tall, producing one or more unbranched stems at the base that are erect to ascending. The stems are light green to reddish green and glabrous to densely pubescent. Along each stem, there are numerous alternate leaves that are ascending to widely spreading. Individual leaves are 2-6" long and 1/8-1/2" across; they are linear to linear-lanceolate and smooth along their margins. Their upper surfaces are medium green and glabrous. The leaves often curve upward along their central veins. The petioles of the leaves are about Â¼" long and light green. Globoid umbels of greenish white flowers about 1Â½-2" across develop from the axils of the middle to upper leaves (one umbel per leaf). Each umbel has 30-100 flowers on pedicels about Â½-Â¾" long. The slender pedicels are light green and pubescent. Individual flowers are about 1/8" across and 1/4" long. Each flower has 5 sepals, a corolla with 5 narrow lobes, 5 upright hoods without horns, and a short central column containing the reproductive organs. The lobes of the corolla hang downward from the face of the flower (pointing toward the center of the umbel). The lobes are mostly greenish white, although they become purplish toward their tips. The peduncles of the umbels are about 1-1Â½" long, light green, and pubescent. The blooming period occurs from mid- to late summer and lasts about 2 months. Fertile flowers develop into follicles (seedpods that split open along one side) about 4-5" long and up to Â½" across that are narrowly lanceoloid in shape. The surface of each follicle is canescent and smooth. Each follicle contain numerous seeds with tufts of white hair that are released to the wind at maturity. The root system consists of a taproot. This wildflower spreads by reseeding itself.
Growing Tall Green Milkweed Seeds:
Though this plant can tolerate some dryness, occasional watering may be necessary. The flowers attract bees and butterflies, especially monarch butterflies. This plant will reseed itself, but volunteer plants can easily be removed if not wanted.

Harvesting Tall Green Milkweed: This makes a striking cut flower. Cut the stems long, choosing flowers that have just opened. Keep in mind that the milky sap is mildly toxic and can irritate the skin.
Saving Tall Green Milkweed Seeds:
After the plant finishes flowering, 3-4â narrow pods will form. Be sure to harvest the pods before they split and the silky fluff carries the seeds away on the wind. As soon as the seeds inside the pod ripen to their mature brown color, remove the pods and spread them out to dry. Split open the pods and take out the silky seed material. Remove the fluff from the seeds. Store the seeds in a cool, dry place.
