NATIVE PLANT INFORMATION NETWORK

Welcome to the Native Plant Information Network (NPIN). Our goal is to assemble and disseminate information that will encourage the sustainable use and conservation of native wildflowers, plants and landscapes throughout North America. NPIN is designed to inform a broad audience ranging from members of the general public such as homeowners, wildflower enthusiasts, and gardeners to practicing professionals such as botanists, land managers, and government personnel.

About the Native Plant Information Network (NPIN)

Now, more than ever, there is a need to bridge the gap between people and the natural world, a need to foster understanding and appreciation of the plant world, and a need to provide local, regional, and national audiences with scientifically accurate resources about their native plant heritage. Since its inception in 1982, the Wildflower Center has fulfilled those needs beginning with a mail-order Clearinghouse and continuing with its modern-day equivalent, the Native Plant Information Network (NPIN) - the Wildflower Center's national web portal for native plant information and resources.

Dark, furrowed bark on the trunk. Wide-spreading branches form an upright, umbrella-like crown in the woods or a round-topped crown in the open. The well-formed trunk is usually devoid of branches a considerable distance from the ground. Leaves up to 2 feet long with 5 to 11 pairs of leaflets along a central axis and a single leaflet at the tip; midrib of the lateral leaflets off-center with the wider part of the blade toward the leaf tip. Leaflets emerge very late in spring and are yellow-green. Fall color is clear yellow, unless the tree has been troubled with insects or leaf blight. Flowers inconspicuous, in elongate, green clusters. Fruit 1 1/2 to 2 1/4 inches in diameter, consisting of a hard-shelled, furrowed nut enclosed in a green husk, darker when ripe.
