Edible Uses                                         
Edible Parts: Fruit;  Leaves.
Edible Uses:

Fruit - raw or cooked[61, 177]. Sweet and juicy[11, 183], it is very nice in small quantities[K]. Very seedy[105]. The skin is rather tough and unpleasant, but the pulp is delicious with a custard-like texture[K]. This fruit gained very high marks from a group of 7 people in a fruit-tasting visit to various gardens[K]. The fruit is about 2cm in diameter[200]. Young leaves - cooked[105, 177, 183].
Medicinal Uses

None known
Other Uses
Wood.

Wood - very hard and heavy. Used for mallets etc[151].
Cultivation details                                         
An easily grown plant, it succeeds in any soil of good or moderate fertility[1], ranging from acid to shallow chalk[200]. Does not like chalky soils according to other reports[184, 188]. Grows well in heavy clay soils. Prefers a rich well-drained loamy soil and a position that is at least partially sunny[11]. A very ornamental plant[1], it is hardy to about -20°c[184]. A number of named forms have been developed for their ornamental value[182]. Plants are slow-growing when young, they speed up somewhat after a few years but then soon slow down again[202]. This sub-species of C. kousa grows more freely, flowering and fruiting better in Britain though it barely differs in appearance from the species[11]. Plants in this genus are notably resistant to honey fungus[200].
                                                                                 
Propagation                                         
Seed - best sown as soon as it is ripe in a cold frame or in an outdoors seedbed if there is sufficient seed[80, 113]. The seed must be separated from the fruit flesh since this contains germination inhibitors[80, 164]. Stored seed should be cold stratified for 3 - 4 months and sown as early as possible in the year[164]. Scarification may also help as may a period of warm stratification before the cold stratification[80, 164]. Germination, especially of stored seed, can be very slow, taking 18 months or more[164]. Prick out the seedlings of cold-frame sown seeds into individual pots as soon as they are large enough to handle and grow the plants on for their first winter in a greenhouse, planting out in the spring after the last expected frosts. Cuttings of half-ripe side shoots, July/August in a frame[188]. Cuttings of mature wood of the current year's growth, taken with a heel if possible, autumn in a cold frame. High percentage[78]. Layering of new growth in June/July. Takes 9 months[78].

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

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.

A bit dated but a good book on propagation techniques with specific details for a wide range of plants.

Does not deal with many species but it is very comprehensive on those that it does cover. Not for casual reading.
[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 detailed book on propagating trees. Not for the casual reader.

A very small handbook, it does give a little bit of information on Korean plants.

Very readable magazine with lots of information on propagation. A good article on Yuccas, one on Sagebrush (Artemesia spp) and another on Chaerophyllum bulbosum.
[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.
[182]Thomas. G. S. Ornamental Shrubs, Climbers and Bamboos.
Contains a wide range of plants with a brief description, mainly of their ornamental value but also usually of cultivation details and varieties.
[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.
[184]Phillips. R. & Rix. M. Shrubs.
Excellent photographs and a terse description of 1900 species and cultivars.

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.
[202]Davis. B. Climbers and Wall Shrubs.
Contains information on 2,000 species and cultivars, giving details of cultivation requirements. The text is terse but informative.
