QUERCUS palustris 'Sovereign'
Pin Oak, Sovereign Pin Oak
This entry has yet to be reviewed and approved by L2G editors.
The Sovereign pin oak fails to produce lower branches that angle sharply downward, unlike the wild species. This cultivar also produces excellent vigor and canopy form, as well as attractive foliage. Native to northeastern and central North America, pin oak is a tall, hardy, deciduous shade tree. Its crown is unique in that its bottom branches point downward, its central branches are horizontal and its upper branches point skyward. This tree has a strong leader and develops gray-brown bark that is smooth when trees are young and shallowly fissured when mature. The shiny, deeply lobed leaves of pin oak are yellow-green in spring, glossy dark-green in the summer and turn to scarlet, bronze-russet or red-brown in fall. If trees suffer inadequate growing conditions over summer they will produce little to no significant fall color. The wind-pollinated flowers occur in spring prior to leaf emergence. The acorns take two years to mature.
Pin oak performs well in full to part sun and well drained, acidic soil. If soils are not acidic enough, 'Sovereign' will develop a yellowing of the leaves, or chlorosis. In the landscape it is best grown as a shade tree for naturalistic landscapes, parks and large yards. This cultivar may be difficult to acquire because of propagation difficulties. It does not always graft well. The lack of weeping lower branches makes it an exceptional park and street tree candidate, especially in wet soil pockets.
