In the original description of Hamamelis vernalis, C. S. Sargent erroneously figured the flowers of H. virginiana (plate 156) and failed to mention either the fragrance or the distinctive color range of the flowers in H. vernalis. He stated only that the petals were light yellow.
Hamamelis vernalis is restricted to the Ozark Plateau of Missouri, Oklahoma, and Arkansas, often in close proximity with the more widespread H. virginiana. It is difficult to explain the restricted occurrence of H. vernalis in the Ozark area, although ancient geology of the area, with predominently Paleozoic rocks, makes it a well-known refugium. Hamamelis vernalis and H. virginiana are sympatric, sometimes growing within 30 m of each other, yet their identity is maintained, and the two species are easily distinguished through a composite of diagnostic characters (J. L. Bradford and D. L. Marsh 1977). Hamamelis vernalis shows an unusual color range of the flowers. Plants growing side by side commonly differ in flower color, varying from orange to deep red or, occasionally, deep yellow. Sometimes flower color varies on the same plant; e.g., petals that are initially deep red can later fade to yellow.
Hamamelis vernalis is not well known in cultivation and is infrequently planted. It is desirable for the fragrance and color variation of the flowers.
