Ilex aquifolium Holly Evergreen shrub (1 Page of 5) The Ilex aquifolium plant species is found in Britain. It is a member of the Aquifoliaceae family. Common gardeners may know the plant as Holly. Some home gardeners know the variety as I. balearica. Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Ilex aquifolium Common Name: Holly Family: Aquifoliaceae Author: L. Known Hazards: The plant is poisonous[10], but only in very large doses[65, 76]. Mature Height: 9 Mature Width: 5 Habitat: Found in most well-drained soils in scrub, hedges and woodland where it is often the dominant under-storey shrub[7].
Cultivation Notes: Succeeds in most soils, including peat, chalk, gravels, sand and shales[186], so long as they are not water-logged, though wild plants are occasionally found in situations with standing winter water[186]. Grows well in heavy clay soils[186]. Established plants are fairly drought tolerant[186]. Dislikes dry soils according to one report[31] whilst another says that it succeeds in dry shade[188]. Tolerates a pH range from 3.5 to 7.2[186]. Succeeds in full sun or fairly dense shade[17, 28, 31], self-sown seedlings from woods and shady places making the most shade tolerant plants[28]. Tolerant of maritime exposure[75] though in such a situation it may lose some or all its leaves in the winter[186].
Plants require a minimum July temperature of 12°c for good fruit production[186]. They tolerate short periods in winter down to -15°c[184]. Severe frosts can kill whole branches, especially if they are open to the sky[186]. The young growth in spring can be damaged by late frosts.
A very ornamental plant, there are many named varieties[182]. Flowers and fruits are formed on wood of the previous year's growth[229]. A good bee plant[108], the minute flowers are sweetly scented[245]. The fruit is a valuable winter food source for birds.
Resents root disturbance, especially as the plants get older[11]. 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]. Only move the plants in May or, preferably, in September[1].
Plants are quite slow growing, even when in good soils and situations[11, 75].
Trees are usually dioecious but hermaphrodite forms are available. Male and female plants must usually be grown if seed is required.
Plants are capable of regenerating from the main stem both above and below ground level and, although the top may be killed in a fire, the plants will usually regrow from the base[186].
Rabbits are particularly fond of this species and will quickly remove the bark.
This species is notably resistant to honey fungus[200].
