Physical Characteristics

A decidious tree growing to 15m by 10m . It is hardy to zone 6. It is in flower from July to August, and the seeds ripen from August to October. The scented flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects. We rate it 2/5 for edibility and 2/5 for medicinal use.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and can grow in heavy clay soil. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires moist soil.

Other Uses

Charcoal Wood.

Wood - hard, close grained, warps badly[158]. It makes a good charcoal[146, 158].

Cultivation details

An easily grown plant, it succeeds in any soil of good or moderate fertility[1], ranging from acid to shallow chalk[200]. Grows well in heavy clay soils. Succeeds in full sun or light shade[[188].
A very ornamental tree[1]. There is some confusion between this species and C. controversa[11].
Plants usually fruit heavily in Britain[11].
The flowers have a soft sweet perfume[245].
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].

Scent

Flowers: Fresh: The flowers have a soft sweet perfume.
