Cultivation details                                         
Prefers a rather dry poor soil in full sun[1, 200]. Succeeds in a hot dry position, and dislikes wet soils[K]. Although a perennial when grown in warmer climates than Britain, it is best treated as a half-hardy annual in this country[1]. There are some named forms selected for their ornamental value[188].
                                                                                 
Propagation                                         
Seed - sow early spring in a greenhouse, pricking out the seedlings into individual pots when they are large enough to handle. Plant out after the last expected frosts. The seed can also be sown in situ in late spring, though the plants will not grow so large this way.

  [K] Ken Fern Notes from observations, tasting etc at Plants For A Future and on field trips.

[1]F. Chittendon. RHS Dictionary of Plants plus Supplement. 1956
Comprehensive listing of species and how to grow them. Somewhat outdated, it has been replaces in 1992 by a new dictionary (see [200]).
[50]? Flora Europaea
An immense work in 6 volumes (including the index). The standard reference flora for europe, it is very terse though and with very little extra information. Not for the casual reader.
[105]Tanaka. T. Tanaka's Cyclopaedia of Edible Plants of the World.
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.
[161]Yanovsky. E. Food Plants of the N. American Indians. Publication no. 237.
A comprehensive but very terse guide. Not for the casual reader.
[176]Yeung. Him-Che. Handbook of Chinese Herbs and Formulas.
An excellent Chinese herbal giving information on over 500 species. Rather technical and probably best suited to the more accomplished user of herbs.
[177]Kunkel. G. Plants for Human Consumption.
An excellent book for the dedicated. A comprehensive listing of latin names with a brief list of edible parts.
[188]Brickell. C. The RHS Gardener's Encyclopedia of Plants and Flowers
Excellent range of photographs, some cultivation details but very little information on plant uses.
[200]Huxley. A. The New RHS Dictionary of Gardening. 1992.
Excellent and very comprehensive, though it contains a number of silly mistakes. Readable yet also very detailed.
[238]Bown. D. Encyclopaedia of Herbs and their Uses.
A very well presented and informative book on herbs from around the globe. Plenty in it for both the casual reader and the serious student. Just one main quibble is the silly way of having two separate entries for each plant.
