Polyscias fruticosa, or Ming Aralia, is a perennial dicot evergreen
shrub or dwarf tree native to India. The plant grows fairly slowly
but can reach up to 1 to 2 meters in height. The leaves are of a
dark green pigment, glossy in texture, and are tripinnate and appear
divided. Individual leaves vary from narrowly ovate to lanceolate
and are about 10 cm long.
Location
The Ming Aralia is widely cultivated in several countries of
southeastern Asia and the tropical islands of the Pacific region. It
was originally located in Polynesia and thrives in environments of
medium humidity, with temperatures varying from 16-29⁰C (60-85⁰F).
Genus: Polyscias
The name Polyscias means many-shaded, in reference to the foliage
found on these plants. Their stalks carry compound leaves with up to
seven (or more) opposite leaflets. In several species the leaves are
deeply lobed. There are about six species of the genus Polyscias
which are actively cultivated. The genus contains a variety of
tropical plants which include about 80 species from the Pacific
islands and Southeast Asia.
Family: Araliaceae
The family, Araliaceae, to which the Polyscias genus including
Ming Aralia belongs, gives rise to a multitude of trees or shrubs
that contain gum and resin ducts. As a whole, the family contains
plants that have leaves of alternate, palmately or pinnately
compound or simple, with stipules. The inflorescences are generally
umbellate, and often arranges in compound umbels, caouttules,
panicles or races. They possess flowers of smaller size than the
dioecious which are bisexual or unisexual. This family also includes
a multitude of popular house plants, including English ivy, as well
as the herb ginseng. Araliaceae is known as the ginseng family,
which is where the traits of the Ming Aralia spice and medical herb
originate. Plants of this family can be found throughout the
Neotropics, for the greater part in mountainous regions and much
less in the lowlands.
Uses
Besides being a house plant…
In Asian countries, the leaves of the Polyscias fruticosa are
used as a tonic, anti-inflammatory, antitoxin, and an antibacterial
ointment. They have also been proven to be an aid in digestion. The
root is also used as a diuretic, febrifuge, anti-dysentery, and is
employed for neuralgia and rheumatic pains. Alongside with medicinal
purposes, Polyscias fruticosa is also used as an ornamental plant
and a spice.
A recent study on this plant by Vo Duy Hunan and colleagues, has
afforded two known oleanolic acid saponins from the leaves, and
polyacetylenes from the roots. This shows antibacterial and
antifungal activities. The volatile leaf oils were also studied and
isolated to find eight new oleanolic acid saponins, named
polysciosides A to H, and three known saponins.
[edit] House Plant Care
When considering this plant for home aesthetics you should keep
in mind the optimum Polyscias fruticosa need full sun to partial
shade or high interior lighting. When grown in the greenhouse, the
soil mixture should consist of two parts peat moss to two parts loam
to one part sand or perlite. When watering, keep in mind that the
plant ought to be kept moist and should never be allowed to dry
thoroughly. Also note that during the winter months, water should be
restricted, but the plant should never be allowed to dry out
completely. The plants should be fertilized only three times during
the growing season using a balanced fertilizer diluted to half the
strength recommended on the label. Since the plants are fairly slow
growers, very little pruning is needed to keep the desired form.
However, remember that unlike plants that branch sideways, the Ming
Aralia grows vertically. Trimming is useful in keeping the desired
height as well as shape. The tips are trimmed in order to encourage
more rapid branching and thickening of the trunk. The joints,
closely set, then produce a thick growth of branches and a dense
covering of leaves, which is an ideal look for this particular
plant. The stems weave back and forth, creating a complex
interlocking arrangement. As the plant ages, the lower branches die
off, leaving a corky surface that is gnarled where the branches had
been. This appearance is what attracts many people to adopting these
plants for decoration of their homes and offices.
