Black tupelo

Nyssa sylvatica is cultivated as an ornamental tree in parks and large gardens, where it is often used as a specimen or shade tree. The tree is best when grown in sheltered but not crowded positions, developing a pyramidal shape in youth, and spreading with age. The stem rises to the summit of the tree in one tapering unbroken shaft, the branches come out at right angles to the trunk and either extend horizontally or droop a little, making a long-narrow, cone-like head. The leaves are short-petioled and so have little individual motion, but the branches sway as a whole... Its often spectacular autumnal coloring, with intense reds to purples, is highly valued in landscape settings. It is the most fiery and brilliant of the 'brilliant group' that includes maple, dogwood, sassafras, and sweet gum, as well as various species of tupelo.
Photographed yesterday at the University of Wisconsin Arboretum.  I was late getting there this autumn and missed most of the great foliage, but this gum tree was still absolutely magnificent.
