Physical Characteristics
An evergreen shrub growing to 3m. It is hardy to zone 6. It is in leaf all year, in flower in May, and the seeds ripen in September. 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) and are pollinated by Wind.
The plant not is self-fertile.
It can fix Nitrogen.
We rate it 3/5 for edibility and
2/5 for medicinal use.
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soil.
The plant prefers acid, neutral and basic (alkaline) soils.
It can grow in semi-shade (light woodland) or no shade.
It requires dry or moist soil.
The plant can tolerate maritime exposure.
Habitats and Possible Locations
Hedge, Woodland, Sunny Edge, Dappled Shade.Edible Uses
Condiment; Fruit; Tea.
The following notes are for the closely related M. cerifera. It is
assumed that they also apply to this species[K].
Fruit - raw or cooked[105, 177, 183]. The fruit is about 2 - 4mm in diameter
with a single large seed[200]. There is very little edible flesh and this is
of poor quality[K].
Leaves and berries are used as a food flavouring[62, 105, 177]. An
attractive and agreeable substitute for bay leaves, used in flavouring soups,
stews etc[183].
The dried leaves are brewed into a robust tea[183].
Medicinal Uses
Disclaimer
Astringent; Emetic; Stimulant; Tonic.
The following notes are for the closely related M. cerifera. It is
assumed that they also apply to this species[K].
The root bark is astringent, emetic (in large doses), sternutatory,
stimulant and tonic[4, 21, 46, 165, 213]. It is harvested in the autumn,
thoroughly dried then powdered and kept in a dark place in an airtight
container[4]. It is used internally in the treatment of diarrhoea, jaundice,
fevers, colds, influenza, catarrh, excessive menstruation, vaginal discharge
etc[4, 238]. Externally, it is applied to indolent ulcers, sore throats,
sores, itching skin conditions, dandruff etc[4, 238].
The wax is astringent and slightly narcotic[4]. It is regarded as a sure
cure for dysentery and is also used to treat internal ulcers[4].
A tea made from the leaves is used in the treatment of fevers and externally
as a wash for itchy skin[222].
Other Uses
Dye; Hedge; Wax; Wood.
The following notes are for the closely related M. cerifera. It is
assumed that they also apply to this species[K].
A wax covering on the fruit is extracted by scalding the fruit with boiling
water and immersing them for a few minutes, the wax floats to the surface and
is then skimmed off. The fruit is then boiled in water to extract the wax
from the pulp and once more the wax is skimmed off. It is then strained
through a muslin cloth and can be used to make aromatic candles, sealing wax
etc[1, 4, 6, 11, 62, 95, 171, 245]. Candles made from this wax are quite
brittle but are less greasy in warm weather[213]. They are slightly aromatic,
with a pleasant balsamic odour[245], and do not smoke when put out, making
them much more pleasant to use that wax or tallow candles[213]. The wax is
also used in making soaps[213]. About 1 kilo of wax can be obtained from 4
kilos of berries[4].
A blue dye is obtained from the fruit[6].
The plant can be grown as an informal hedge[200], succeeding in windy
sites[K].
Wood - light, soft, brittle, fine-grained[82, 227]. The wood weighs 35lb per
cubic foot[227]. It is of no commercial value[229].
Cultivation details
Prefers a moist soil[200]. Grows well in an open position in a
well-drained soil in sun or light shade[200]. Thrives in any ordinary garden
soil according to one report[11] whilst another says that it thrives in an
acid soil[182]. Prefers a lime-free loamy or peaty soil[1]. Succeeds in dry
and maritime climates[200].
Closely related to M. pensylvanica and M. cerifera[200].
Dioecious, male and female plants must be grown if seed is required.
Plants in this genus are notably resistant to honey fungus[200].
Many species in this genus have a symbiotic relationship with certain soil
micro-organisms, these form nodules on the roots of the plants and fix
atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant
but some can also be used by other plants growing nearby[200].
Propagation
Seed - best sown as soon as it is ripe in the autumn in a cold
frame[78]. Stored seed germinates more freely if given a 3 month cold
stratification and then sown in a cold frame[78]. Germination is usually
good[78]. Prick out the seedlings into individual pots when they are large
enough to handle and grow on in a cold frame for the first winter. Plant out
in late spring or early summer[K].
Cuttings of half-ripe wood, 5 - 8cm with a heel, July/August in a frame. Pot
up and overwinter in a cold frame then plant out in late spring or early
summer. Fair to good percentage[78].
Layering in spring[200].
