Abstract

A new variety of Amelanchier grandiflora is disclosed which is characterized by its unique yellow flower buds unfold into white flowers, its wide-spread branches, and, most particularly, by a brilliant red fall foliage display.

Description

The present invention relates to a new and distinct variety of Amelanchier grandiflora which was found in a cultivated area.

The distinct characteristics of the tree of the present invention are that white flowers unfold from yellow-tinged flower buds, the fall foliage is a brilliant red color, and the branches are very wide-spread. These characteristics are significantly different from other varieties of Amelanchier grandiflora.

Asexual reproduction of the new variety was accomplished by tissue culture of new bud cells, and showed that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying drawing shows a typical tree specimen of the new variety, together with typical foliage and flower specimens on a larger scale.

The following is a detailed description of the new variety, with color terminology in accordance with the Inter-Society Color Council -- National Bureau of Standards Circular 553 Color Chart, except where general color terms of ordinary dictionary significance are obvious.
