ailanthus altissima seeds Heaven Tree
LATIN NAME: Ailanthus altissima
COMMON NAME: Tree of Heaven
The tree of heaven is a fast, tough, upright tree of the waysides, and its long, pinnate leaves and its broad, open crown have made it one of the most familiar of the city trees. It grows as a deciduous tree, reaching up to twenty metres or more, with the smooth, greyish bark and the broad, open crown bearing the long, pinnate leaves of many leaflets, with a small, glandular tooth at the base of each leaflet, and, in the early summer, the large, upright clusters of the small, greenish-yellow flowers, followed by the dense, showy clusters of the small, winged, reddish fruits, while the male and the female flowers are borne on the separate trees. It is a species of the flowering tree in the quassia family, and it is native to the central and the northern China and the Taiwan, while it has been carried to the many warm parts of the world, and it is known as the tree of heaven.
The tree of heaven belongs to the quassia family, Simaroubaceae, and it is a species of the deciduous tree, native to the central and the northern China and the Taiwan, while it has been introduced to the many parts of the world, and it is known as the tree of heaven. It is prized for its fast growth and its tolerance of the poor soils and the city air, though it is a vigorous, spreading tree that needs a careful hand.
Scientific Research & Plant Biotechnology
The tree of heaven has a real and complicated place in the research. It has been studied in the botany and the ecology, since it is a fast, tough tree that spreads readily through the disturbed ground and the cities, and researchers have examined its growth, its spread and its ways of surviving on the poorest soils, while its spread through the warm regions has drawn attention in the international ecological press as a vigorous tree of the waysides. The plant has also been studied in the chemistry of the natural products, since the bark and the leaves contain a range of the bitter compounds, and researchers have examined these constituents and their potential uses, while the chemistry of the quassia family has been of continuing interest, and the plant is best appreciated as a subject of study and of the traditional use rather than a casual remedy. The species has also been studied in the traditional medicine and the history, since the bark of the tree of heaven has a long history of use in the traditional ways of the East, and its uses have been examined, while the study of the medicinal plants of the region has been of continuing interest. For a tree of such vigour, the tree of heaven has a rich and continuing record of study, and its spreading ways are best managed with care.
Ecological & Economic Value & Wide Applications
Ecologically, the tree of heaven is a hardy tree of the difficult ground. Its broad, open crown gives a quick shade and a shelter to the birds, and its small, winged fruits feed the seed-eating birds, while its fast, tough growth lets it thrive on the poor soils and in the city air. Because it spreads so readily by its winged seeds, it is a tree best planted with thought for where its offspring will appear.
Its economic value is real in its own way. The tree of heaven is valued for its fast growth and its tolerance of the poor soils, and its toughness has drawn attention in the international ecological and forestry press, while the bark of the tree has a long history of use in the traditional ways of the East. For a grower, the tree of heaven is an easy and vigorous tree, though it is best planted with a care for its spreading ways, and it will reward a gardener with a fast, tough, shade-giving tree. The seeds are easy to start — sow them just below the surface of a pot of moist, well-drained soil, keep them lightly watered, and they’ll be sprouting readily, growing on into a fast, tough, broad-crowned tree.
Genus: Ailanthus
Species: altissima
Common Name: Tree of Heaven
Pre-treatment: required
Height / Spread: 18m/12m
Plant Type: Medium Tree
Growth rate: very fast (up to 2 m 1st year)
Vegetation type: decidious
Germination rate: very high
Leaf /Flower color: green/yellow green
this tree are deep green, coarsely ferny and have a malodorous smell reminiscent of burnt rubber and peanut butter. Each leaf can have as many as 25 lance-shaped leaflets. This species is mostly dioecious, which means trees produce either male or female flowers, though some trees may have perfect, or bisexual, flowers. The tiny, greenish yellow flowers bloom in spring or summer, depending on geography, and the male flowers emit a foul odor. Bees, beetles and other insects pollinate the blooms. The females produce massive clusters of papery pink or reddish brown seeds. Thousands of the winged seeds (samaras) are produced and germinate quickly and easily. The brittle stems and trunk are covered with smooth gray bark with lighter gray vertical cracks.
