Edible uses

There are no edible uses listed for Ilex x altaclerensis.

Material uses

Makes a good windbreak hedge, succeeding even in exposed maritime areas, though it is slow growing. The vars. 'Hendersonii' (f), 'Hodginsii' (m) and 'Maderensis' (m) are especially noted[3].

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[4][5]. 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. This is a hybrid species so any seedlings will not be true to type.

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[4].

Cultivation

Succeeds in most soils so long as they are not water-logged[6]. Grows well in heavy clay soils.

Dormant plants are hardy to about -15°c if they are given shelter from cold drying winds[7]. The young growth in spring can be damaged by late frosts. Tolerates industrial pollution and maritime exposure[6]. Slow growing. Plants are very tolerant of trimming and can be pruned right back into old wood. A very ornamental plant, there are many named varieties[8]. Dislikes root disturbance, especially as it gets older[9]. 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[K]. Any transplanting is best done in May or, preferably, in September.

Dioecious. Male and female plants must be grown if seed is required.
