Medicinal use of Purple Milkweed:
The latex is used as a cure for warts.Description of the plant:
Plant:
PerennialHeight:
75 cm(2 feet)
Flowering:
June toAugust
Habitat of the herb:
Dry to moist thickets, woods and openings.Edible parts of Purple Milkweed:
The following uses have been recorded for A. speciosa, it is fairly safe to assume they can also be applied to this closely related species. Flower buds - raw or cooked. Tasting somewhat like peas. Young shoots and leaves - cooked. An asparagus substitute. They should not be eaten raw. Tips of older shoots are cooked like spinach. Young seed pods, 3 - 4 cm long, cooked. Very appetizing. Flower clusters can be boiled down to make a sugary syrup or they can be eaten raw. Seed - raw. A chewing gum can be made from the latex contained in the stem and leaves. Root.No further details.Other uses of the herb:
The following uses have been recorded for A. speciosa, it is fairly safe to assume they can also be applied to this closely related species. A good quality tough fibre is obtained from the bark. It is used in twine, coarse cloth, paper etc. The fibre is 10 - 45mm long. It is easily harvested in late autumn, after the plants have died down, by simply pulling it off the dead stems. When making paper, the stems can be retted by leaving them in the ground until they are dry in the winter or they can be harvested in late summer, the leaves removed and the stems steamed to remove the fibre. The stems are then cooked for two hours with lye and pounded with mallets. The paper colour varies from white to creamy green depending on how the paper is made. If the stems are used in the summer the latex will often find its way onto the fibres and is hard to remove. The seed floss is used to stuff pillows etc or is mixed with other fibres to make cloth. It is a Kapok substitute, used in Life Jackets or as a stuffing material. It is very water repellent. The floss has also been used to mop up oil spills at sea. Rubber can be made from latex contained in the leaves and the stems. The yield is up to 3%. Pods contain an oil and a wax which are of potential importance. A green dye is obtained from the flowers and leaves combined.Propagation of Purple Milkweed:
Seed - best sown in a greenhouse as soon as it is ripe in the autumn or in late winter. We have also had good results from sowing the seed in the greenhouse in early spring, though stored seed might need 2 - 3 weeks cold stratification. Germination usually takes place in 1 - 3 months at 18°C. As soon as the seedlings are large enough to handle, prick them out into individual pots and grow them on in the greenhouse for their first winter. Plant out when they are in active growth in late spring or early summer and give them some protection from slugs until they are growing away strongly. Division in spring. With great care since the plant resents root disturbance. Pot the divisions up and place them in a lightly shaded position in the greenhouse until they are growing away strongly, then plant them out in the summer, giving them some protection from slugs until they are established. Basal cuttings in late spring. Use shoots about 10cm long with as much of their white underground stem as possible. Pot them up individually and place them in a lightly shaded position in a greenhouse until they are rooting and growing actively. If the plants grow sufficiently, they can be put into their permanent positions in the summer, otherwise keep them in the greenhouse until the following spring and when they are in active growth plant them out into their permanent positions. Give them some protection from slugs until they are established.Cultivation of the herb:
Dry to moist thickets, woods and openings.Known hazards of Asclepias purpurascens:
Although no specific reports have been seen for this species, many, if not all, members of this genus contain toxic resinoids, alkaloids and cardiac glycosides. They are usually avoided by grazing animals.Plant information taken from the Plants For A Future.
