How to Grow
We have very little information on this species and do not know if it will be hardy in Britain. There are two main forms of the plant, the type variety (Eriogonum alatum var. alatum) is rarely cultivated since an individual plant may go up to seven (or more) years before flowering, after which it dies. It is unclear whether the variety glabriusculum also does this. The notes below are based on the needs of other members of this genus. Requires a loose lean gritty well-drained soil in a very sunny position. Succeeds in dry soils. Tolerates exposed positions. Requires some protection from winter wet. Established plants resent root disturbance.
Propagation: Sow seed as soon as it is ripe in autumn in a sandy compost in a greenhouse. Stored seed can be sown in early spring in a warm greenhouse. Prick seedlings into individual pots once large enough to handle and grow on under glass for at least their first winter. Plant out in late spring or early summer after the last expected frosts. Division in early spring must be done carefully, as the plant resents root disturbance. Work around the edges of the clump without lifting the whole plant, teasing out divisions with as much root as possible, then pot them up and grow in light shade in the greenhouse until well rooted before planting out in summer. Cuttings of greenwood with a heel can also be taken in summer.
Medicinal Uses
The plant has been used to treat pain and to make a lotion for rashes. A cold infusion of the root treats diarrhoea and severe coughs, and has also been used as a mouthwash for sore gums. The powdered root mixed with oil serves as a dressing for a baby's sore navel. The Navajo (Diné) people regard this species as a 'life medicine,' using a mixture of shredded roots and water primarily to treat internal ailments, and also employing it as a ceremonial medicine. The Zuni use it as an emetic for stomachaches.
