Agoseris glauca (common name: mountain dandelion)

Propagation: Seed - sow spring in a greenhouse. The seed usually germinates in 2 - 6 weeks at 15°c[1]. As soon as the seedlings are large enough to handle, prick them out into individual pots and plant them out in the summer or late in the following spring.

Division with care in spring[2]. The plants do not like a lot of root disturbance so it is best to pot up the divisions and keep them in a cold frame or greenhouse until they are established.

Cultivation: Prefers full sun and a sandy or gravelly loam low in nutrients[3][2].

The sub-species A. glauca villosa is used for its gum[4].

Range: Western N. America - British Columbia to Manitoba, south to California and New Mexico.

Habitat: Meadows and other open places at all elevations[5] in moderately dry to moist or even wet soils[6].

Edibility: The solidified sap (latex) of the stem is chewed as a gum[7][8][4][6][9].

Medicinal: The following reports refer to the sub-species A. glauca dasycephala (Torr.&Gray.)Jepson.

An infusion of the entire plant is used as a wash for sores and rashes[9].

The milky latex is applied to warts in order to remove them[9]. This requires constant applications over a period of weeks for it to be effective[K]. A poultice made from the latex is applied to sores[9].

An infusion of the root is used as a laxative[9].

Usage: A latex in the plant contains rubber, but not in sufficient quantities to make it commercially valuable[6].

Pollinators: Insects

Drainage: Prefers well drained soil.

Seed Ripens: Early Summer-Late Summer

Flower Type: Hermaphrodite

Also Known As: A. villosa. Rydb. Troxicum glaucum.
