|discussion=<p><i>Hypericum frondosum</i> is endemic to the southwestern end of the Appalachian Range; it is recorded as introduced in Connecticut, Massachusetts, and New York (W. P. Adams 1962). Records from Arkansas and, possibly, South Carolina and Virginia appear to be errors for <i>H. prolificum</i>. Although <i>H. frondosum</i> is variable over its natural range and approaches <i>H. prolificum</i> morphologically in Arkansas, it remains distinct from its immediate relatives. In cultivation, it sometimes hybridizes with <i>H. prolificum</i>. Artificial hybrids have been made, as well as artificial tetraploids (O. Myers 1963).</p>
