Abstract

A new and distinct cultivar of Forsythia plant is provided that is a seedling formed following the induced mutation of the ‘Spring Glory’ cultivar (non-patented in the United States). Gamma radiation was utilized to create the mutation. The new cultivar can be readily distinguished from the parent cultivar by the presence of a wide prostrate slow-growing growth habit. Anthocyanin coloration is present at the apex of the sepals. Attractive wide-opening yellow flowers are formed commonly on a single basis with one flower being formed per bud. The winter hardiness is good. The new cultivar also is well suited for growing as attractive ornamentation in the landscape where good control of plant height is to be maintained. The new cultivar requires no special care.
