Physical Characteristics
A decidious Tree growing to 9m.
It is hardy to zone 8. It is in flower from April to June, and the seeds ripen in October. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required)The plant is not self-fertile.
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils.
The plant prefers acid, neutral and basic (alkaline) soils.
It cannot grow in the shade.
It requires dry or moist soil.
Young shoots and leaves - cooked. Used as a vegetable[11, 46, 182, 183].
Seed - cooked. It is roasted and then eaten, or is used in confectionery[105, 183].
Medicinal Uses
Plants For A Future can not take any responsibility for any adverse effects from the use of plants.
Always seek advice from a professional before using a plant medicinally.
The plant can be used as a rootstock for the pistachio nut, P. vera[200].
A yellow dye can be obtained from the wood[266].
Wood - hard, durable. Used in furniture making and carpentry[51, 266].
Cultivation details
Succeeds in an ordinary loamy soil and in dry soils[1, 11]. Requires a sunny position[1].
This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[200].
A very ornamental tree[1, 11].
Any pruning that needs to be done is best carried out in the spring[238].
This species strongly resents being transplanted[113], it should be planted out into its permanent position as young as possible and given some protection from winter cold for its first few winters outdoors.
Dioecious, male and female plants must be grown if seed is required.
Propagation
Pre-soak the seed for 16 hours in alkalized water[78], or for 3 - 4 days in warm water[1], and sow late winter in a cold frame or greenhouse[78, 113]. Two months cold stratification may speed up germination, so it might be better to sow the seed in early winter[113]. The germination is variable and can be slow. Prick out the seedlings into individual pots when they are large enough to handle and grow on the plants for at least their first winter in a greenhouse. Plant out into their permanent positions in early summer and consider giving some protection from winter cold for their first year or two outdoors[K].
