Description
Ilex integra is an evergreen Tree growing to 6 m (19ft) by 5 m (16ft). See above for USDA hardiness. It is hardy to UK zone 7. It is in leaf all year, in flower in April, and the seeds ripen from August to October. The species is hermaphrodite (has both male and female organs). Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
Edible Uses
Young leaves - cooked. A famine food, it is only used when all else fails.
Known Hazards
Although no specific reports of toxicity have been seen for this species, the fruits of at least some members of this genus contain saponins and are slightly toxic. They can cause vomiting, diarrhoea and stupor if eaten in quantity.
Distribution
E. Asia - E. China, Japan, Korea.
Where It Grows
TEMPERATE ASIA: China, Korea, Japan, Taiwan
Cultivation
Succeeds in most soils so long as they are not water-logged. Somewhat tender for its first two or three years from seed, this species is hardy to about -10°c when it gets older. Resents root disturbance, especially as the plant grows older. It is best to place the plants into their permanent positions as soon as possible, perhaps giving some winter protection for their first year or two. Plants are very tolerant of pruning and can be cut right back into old wood if required. Dioecious. Male and female plants must be grown if seed is required.
Propagation
Seed - best sown as soon as it is ripe in the autumn in a cold frame. It can take 18 months to germinate. Stored seed generally requires two winters and a summer before it will germinate and should be sown as soon as possible in a cold frame. Scarification, followed by a warm stratification and then a cold stratification may speed up the germination time. The seedlings are rather slow-growing. Pot them up into individual pots when they are large enough to handle and grow them on in light shade in a cold frame for their first year. It is possible to plant them out into a nursery bed in late spring of the following year, but they should not be left here for more than two years since they do not like being transplanted. Alternatively, grow them on in their pots for a second season and then plant them out into their permanent positions in late spring or early summer. Give them a good mulch and some protection for their first winter outdoors. Cuttings of almost ripe wood with a heel, August in a shaded position in a cold frame. Leave for 12 months before potting up. Layering in October. Takes 2 years.
