Edible Uses                                         
Edible Parts: Oil;  Seed.
Edible Uses: Oil.

Seed - raw[105, 117, 257]. The seed is small with a thick shell but it makes good eating[183]. A sweet taste[82, 229]. An edible oil is obtained from the seed, it tends to go rancid quickly.
Medicinal Uses

Other Uses
Dye;  Herbicide;  Oil;  Rootstock;  Wood.

This species is often used in south-western N. America as a vigorous disease-resistant and drought tolerant rootstock for J. regia[117, 183, 229]. A black dye is obtained from the seed husks[257]. Plants produce chemicals which can inhibit the growth of other plants. These chemicals are dissolved out of the leaves when it rains and are washed down to the ground below, reducing the growth of plants under the tree[18, 20, 159]. The roots of many members of this genus produce substances that are toxic to many plant species, especially apples (Malus species), members of the Ericaceae, Potentilla spp and the white pines (certain Pinus spp.)[200]. Wood - heavy, hard, rather coarse grained[82]. A valuable timber, the tree is occasionally cultivated for its wood[229].
Cultivation details                                         
Requires a deep well-drained loam and a sunny position sheltered from strong winds[1, 11]. Prefers a slightly alkaline soil[200]. The plant's deep taproot gives the tree some degree of drought tolerance[229]. Plants are hardy at Kew[11], though they do not succeed in the colder areas of the country[200]. This species is occasionally cultivated for its edible seed[117]. There are also some named forms that have been selected for their use as a rootstock[183]. Plants produce a deep taproot and they are intolerant of root disturbance[1, 11]. Seedlings should be planted out into their permanent positions as soon as possible and given some protection for their first winter or two since they are somewhat tender when young[1, 11]. Flower initiation depends upon suitable conditions in the previous summer[200]. The flowers and young growths can be destroyed by even short periods down to -2°c, but fortunately plants are usually late coming into leaf[200]. Any pruning should only be carried out in late summer to early autumn or when the plant is fully dormant otherwise wounds will bleed profusely and this will severely weaken the tree[200]. Trees have a dense canopy which tends to reduce plant growth below them. We have no specific information for this species, but the roots of several members of this genus produce substances that are toxic to many plant species, especially apples (Malus species), members of the Ericaceae, Potentilla spp and the white pines (certain Pinus spp.)[200]. The leaves of many species also secrete substances that have an inhibitory affect on plants growing underneath them. All in all this is not a very good companion plant[K]. This species is notably resistant to honey fungus[200].
The seed is best sown as soon as it is ripe in individual deep pots in a cold frame[80]. You need to protect it from mice, birds, squirrels etc. The seed usually germinates in late winter or the spring. Plant out the seedlings into their permanent positions in early summer and give some protection from the cold for their first winter or two. The seed can also be stored in cool moist conditions (such s the salad compartment of a fridge) over the winter and sown in early spring but it may then require a period of cold stratification before it will germinate[78, 80].

Comprehensive listing of species and how to grow them. Somewhat outdated, it has been replaces in 1992 by a new dictionary (see [200]).

A classic with a wealth of information on the plants, but poor on pictures.

Details of beneficial and antagonistic relationships between neighbouring plants.

Fairly good.

A bit dated but a good book on propagation techniques with specific details for a wide range of plants.
[80]McMillan-Browse. P. Hardy Woody Plants from Seed.
Does not deal with many species but it is very comprehensive on those that it does cover. Not for casual reading.
[82]Sargent. C. S. Manual of the Trees of N. America.
Two volumes, a comprehensive listing of N. American trees though a bit out of date now. Good details on habitats, some details on plant uses. Not really 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.

A very readable and comprehensive guide. Well illustrated.
[159]McPherson. A. and S. Wild Food Plants of Indiana.
A nice pocket guide to this region of America.
[183]Facciola. S. Cornucopia - A Source Book of Edible Plants.
Excellent. Contains a very wide range of conventional and unconventional food plants (including tropical) and where they can be obtained (mainly N. American nurseries but also research institutes and a lot of other nurseries from around the world.
[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.
[229]Elias. T. The Complete Trees of N. America. Field Guide and Natural History.
A very good concise guide. Gives habitats, good descriptions, maps showing distribution and a few of the uses. It also includes the many shrubs that occasionally reach tree proportions.
[257]Moerman. D. Native American Ethnobotany
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.
