Comestibilité

  • Racine - cuite [46].
  • Dried then ground into a powder and mixed with corn [61, 105, 161].
  • Use of the root was said by some North American Indian tribes to give one a good appetite and make them fat [257].

Usages médicinaux

  • The plant is cathartic, diaphoretic and emetic [257].
  • The roots and flowers were used by the North American Indians to treat stomach cramps and as a general panacea or 'life' medicine [257].
  • A cold infusion was used as a lotion for sores or sore mouths and also to bathe perspiring feet [257].

Culture

  • Prefers a light well-drained sandy soil in full sun [200].
  • This species is not very hardy in Britain, though it should succeed outdoors in the southern part of the country, especially if given a warm sheltered site [200].
  • The flowers are produced in terminal clusters, they only open in the coolness of the evening, diffusing a vanilla-like perfume [245].
  • Seed is rarely ripened on plants growing in Britain [1].

Propagation

  • Seed - sow autumn or early spring very shallowly in pots of sandy soil in a greenhouse [133].
  • Germination can be very slow unless you peel off the outer skin and pre-soak the seed for 24 hours in warm water [200, 245].
  • The seed usually germinates in 1 - 2 months at 15°c [133].
  • When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter .
  • Seedlings are prone to damp off and so should be kept well-ventilated [200].
  • Plant out in late spring, after the last expected frosts .
  • Cuttings in spring, rooted in sand [200].

Réferences

[1] F. Chittendon. RHS Dictionary of Plants plus Supplement. 1956 1951.
Comprehensive listing of species and how to grow them. Somewhat outdated, it has been replaces in 1992 by a new dictionary (see [200]).
[46] Uphof. J. C. Th. Dictionary of Economic Plants. 1959.
An excellent and very comprehensive guide but it only gives very short descriptions of the uses without any details of how to utilize the plants. Not for the casual reader.
[60] Hitchcock. C. L. Vascular Plants of the Pacific Northwest. 1955.
A standard flora for Western N. America with lots of information on habitat etc. Five large volumes, it is not for the casual reader.
[61] Usher. G. A Dictionary of Plants Used by Man. 1974.
Forget the sexist title, this is one of the best books on the subject. Lists a very extensive range of useful plants from around the world with very brief details of the uses. Not for the casual reader.
[105] Tanaka. T. Tanaka's Cyclopaedia of Edible Plants of the World. 1976.
The most comprehensive guide to edible plants I've come across. Only the briefest entry for each species, though, and some of the entries are more than a little dubious. Not for the casual reader.

Very readable magazine with lots of information on propagation.

A comprehensive but very terse guide. Not for the casual reader.

An excellent, comprehensive book on scented plants giving a few other plant uses and brief cultivation details. There are no illustrations.
[257] Moerman. D. Native American Ethnobotany 1998.
Very comprehensive but terse guide to the native uses of plants. Excellent bibliography, fully referenced to each plant, giving a pathway to further information. Not for the casual reader.
