From Wikipedia, the free encyclopedia
(syn. Heptapleurum arboricolum
) is a flowering plant in the family Araliaceae
, native to Taiwan. It also goes by the common name "Dwarf Umbrella Tree
It is an evergreen shrub growing to 3-6 m tall, free-standing, or clinging to the trunks of other trees. The leaves are palmately compound, with 7-9 leaflets, the leaflets 9-20 cm long and 4-10 cm broad (though often smaller in cultivation). The flowers are produced in a 20 cm panicle of small umbels, each umbel 7-10 mm diameter with 5-10 flowers.
Cultivation and uses
It is commonly grown as a houseplant, popular for its tolerance of neglect and poor growing conditions. It is also grown as a landscape plant in milder climates where frosts are not severe. Numerous cultivars have been selected for variations in leaf colour and pattern, often variegated with creamy-white to yellow edges or centres, and dwarf forms.
The umbrella plant lends itself easily to the bonsai form and is popular as an indoor bonsai.
The plant prefers higher light if possible, but can adapt to a wide variety of light levels. As a tropical plant it likes moisture, but avoid letting the plant sit in water after you water it. It likes to be moist but not wet.
Under the right conditions, this plant will produce aerial roots that, when they reach the ground, will convert to fully functional roots. They give the plant an unusual and interesting appearance. Three conditions must be maintained for the plant to produce them: a high growth rate, insufficient trunk roots (the plant is root bound or these roots are pruned) and constant, very high humidity.
Araliaceae Family (Ivy Family)
are a family of flowering plants, also known as the Aralia
family (after its type genus Aralia
) or ivy
family. The family includes 254 species of trees, shrubs, lianas and perennial herbaceous plants in two subfamilies. Species usually bear pinnately or palmately compound leaves, and usually have small flowers produced in large panicles.
The family from tropical area origin is present in cooler climates, too. They are found in the Americas, Eurasia, Africa, Australia, New Zealand, New Caledonia and Pacific islands. Araliaceae bear essential oils, or without essential oils can be resinous and heterophyllous. It presents many shapes, includes some trees and ivies as the angelica tree (devil's walking-stick, Aralia spinosa
), the devil's club (Oplopanax horridus
spp., including Hedera helix
and herbs as ginseng Panax
spp., a native of Korea and used as medical herb. Leaves are simple, or compound, sometimes lauroid (resembling Laurus) or peltate, or not peltate; when compound, ternate, or pinnate, or palmate.
The systematics of Araliaceae are currently under study, and taxonomic changes and novelties are to be expected. Endemic Araliaceae are found in the pluvial montane forest, very humid montane, and humid lowland river forest regions. They are present, too, in laurel forest, cloud forest and warm, humid habitats. The family is closely related to Apiaceae and Pittosporaceae, and the boundaries between these families and other members of Apiales are still uncertain. Some recent systems included Araliaceae in an expanded Apiaceae, but this has not been widely followed. Molecular phylogenies suggest at least some of the genera traditionally included in Apiaceae as subfamily Hydrocotyloideae appear to be more closely related to Araliaceae, and the inclusion of Hydrocotyle and Trachymene in Araliaceae has been recommended.
The generic level classification of Araliaceae has been unstable; in particular, numerous genera have been synonymized under Schefflera. Recent molecular phylogenies have shown this large pantropical genus is polyphyletic and some believe it should be divided again into several genera, though these would probably not correspond with the previously recognized genera.
