Ailanthus,
The Tree of Heaven

Even though Ailanthus is not an incense or mystical tree, it is an important tree for urban locations and other inhospitable sites. There is something mystical about any tree that can grow where this tree does! It is the famous tree from the book, "A Tree Grows In Brooklin". It is also not an incense tree, since the male flowers are quite stinky! The fruits are toxic as well.But any tree that can add beauty to an ugly world like this one has, is OK by me!

Here are some excellent links to this tree. I wish I could find such informative links like these for the other tree pages! Thanks to Excite. Any help will be greatly appreciated.

  1. Ailanthus, The Tree Of Heaven It was introduced into England from China in the mid-18th century as an ornamental, migrating to the United States in 1874. Ailanthus grows rapidly, achieving its mature height of 90 feet and diameter of 3 feet in little more than a decade.
  2. Ailanthus altissima, Tree of Heaven A. altissima, Tree of Heaven. There is a quirk that runs through the nature of many gardeners a tendency to consider a plant that is difficult to grow as being desirable and to disdain one that happens to be easy to grow; if it is very easy to grow, it is termed "weedy." Because the tree of heaven grows so easily, it can become a nuisance, sending out underground shoots to sprout.

  5. Tree-of-Heaven Ailanthus altissima: The tree-of-heaven was introduced to this country from China during the early part of the last century as a source of food for silkworms.

  9. Ailanthus altissima fact sheet In naturally forested areas, disturbance created by severe storms or insect infestations can open the way for tree-of-heaven infestation. However, to insure the herbicide gets into the root system, it is best to apply this herbicide in the late growing season while the plant is translocating nutrients to its roots.
  10. Early AilanthusThe story goes that in 1853 the Chinese cook of Abel Helman, an early Ashland pioneer, planted the first tree of heaven in this region; the very large tree still guards the entrance to Lithia Park. This tree originates in China and can endure difficult conditions, such as drought, wind, bad soil, and freeway overpasses, to create beauty where none existed before.
