Upright, multistemmed tree to 25', purplish blue fruit, autumn foliage orange to red, white flowers in clusters Description from the Plant Patent (PP6,039)
The present invention relates to a new and distinct variety of Amelanchier believed to be Amelanchier laevis which was found in a cultivated area.
The distinct characteristics of the tree of the present invention is that white flowers unfold before leaves unfold, therefore giving a better flower display than other varieties o Amelanchier laevis in which varieties the leaves unfold prior to or simultaneous with the flowers. The leaves of the new variety are glabrous on the underside, bronze in coloration, and do not have hairs.
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.
