An image of weeping willow (Salix babylonica) is the usual visual association when most people think of a weeping tree. In fact, there are hundreds of tree varieties that express the weeping form - conifers like spruce, hemlock, cypress, cedar and spruce; broadleaves like maple, cherry, birch and willow.
Most weeping plants are the result of grafting a weeping cultivar onto a hardier rootstock. This propagation method make these weepers available at reasonable prices and in many species. Typically weeping-formed trees will occupy a large area and adequate space is required to show it properly. These special trees need special treatment when planting and pruning.
About.com's Landscape (David Beaulieu) and Tree and Shrub (Vanessa Richins Myers) guides make some great recommendations on specific tree hybrids to plant:

Fringetree or Old Man's Beard is a beautiful, small tree when it is in full Spring bloom. It can grow nearly anywhere in the continental United States and is native to the lower eastern U.S. and coastal states to New York. It's white flower color kicks in just as the dogwood blooms are fading.
Although fringetree does well in shade, it never attains its full potential for height and diameter growth without full sunlight. An open-grown fringetree at George Washington's Mount Vernon in Virginia has attained a near record at 32 feet tall with a trunk of 17 inches in diameter.

Tree pollen is a fine to coarse powder containing the genetic material of seed plants - including trees. Tree pollen produces male reproductive cells that have the ability to fuse with female reproductive parts and that union results in pollination.
Tree pollen grains are distributed by either wind or insects and animals.
Small, light tree pollen is blown by wind to female parts while larger tree pollen grains are deposited by insects onto the female ovary where pollination takes place. Tree pollen grains germinate and develop a pollen tube which grows down to the ovary and deposits the sperm cell which causes the production of seed.

A tree is probably the most common, naturally growing or cultivated, living organism you will ever encounter on a daily basis. Most people I know have a real desire to learn more about a tree including looking at a tree in hopes to identify that tree. With this in mind, I have put together a list of tree topics that need some illumination including tree growth, tree tissues, tree identification and much more.
