Abstract

A new and distinct cultivar of Maple tree named ‘RustyAllen’, characterized by its upright pyramidal tree form with upswept branch angles; vigorous growth habit; freely branching habit with numerous lateral branches providing a full and densely foliated appearance; and dark red-colored developing leaves that become dark green in color with development and bright red to dark red and occasionally orange in color during the autumn.

Description

Botanical designation: Acer buergerianum.
Cultivar denomination: ‘RUSTYALLEN’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Maple tree, botanically known as Acer buergerianum, commercially referred to as Trident Maple and hereinafter referred to by the name ‘RustyAllen’.
The new Maple tree is a product of a planned breeding program conducted by the Inventor in Athens, Ga. and Winterville, Ga. The objective of the breeding program is to create new Maple trees appropriate for urban landscapes that have an upright pyramidal tree form, vigorous growth habit and bright red autumn leaf color.
The new Maple tree originated from an open-pollination of an unnamed selection of Acer buergerianum, not patented, as the female, or seed, parent with an unknown selection of Acer buergerianum as the male, or pollen, parent. The open-pollination occurred in a controlled environment in Athens, Ga. in March, 2001. The new Maple tree was discovered and selected by the Inventor as a single plant from within the progeny of the stated open-pollination in a controlled environment in Winterville, Ga. in April, 2004.
Asexual reproduction of the new Maple tree by softwood cuttings in a controlled environment in Winterville, Ga. has shown that the unique features of this new Maple tree are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Trees of the new Maple have not been observed under all possible environmental and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘RustyAllen’. These characteristics in combination distinguish ‘RustyAllen’ as a new and distinct Maple tree:
    • 1. Upright pyramidal tree form with upswept branch angles.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit with numerous lateral branches providing a full and densely foliated appearance.
    • 4. Dark red-colored developing leaves that become dark green in color with development and bright red to dark red and occasionally orange in color during the autumn.
Trees of the new Maple can be compared to trees of the female parent selection. Trees of the new Maple differ primarily from trees of the female parent selection in developing leaf color as trees of the new Maple have dark red-colored developing leaves whereas trees of the female parent selection have yellow green-colored developing leaves.
Trees of the new Maple can also be compared to trees of Acer buergerianum ‘ABMTF’, disclosed in U.S. Plant Pat. No. 16,629. Trees of the new Maple and ‘ABMTF’ differ primarily in the following characteristics:
    • 1. Trees of the new Maple have smaller leaves than trees of ‘ABMTF’.
    • 2. Developing leaves of trees of the new Maple are dark red in color whereas developing leaves of trees of ‘ABMTF’ are yellow green in color.
    • 3. Trees of the new Maple have darker green-colored fully developed leaves than trees of ‘ABMTF’.
    • 4. Leaves of trees of the new Maple are bright to dark red or occasionally orange in color during the autumn whereas leaves of trees of ‘ABMTF’ are yellow, orange red and greyed purple in color during the autumn.
    • 5. Trees of the new Maple flower slightly earlier than trees of ‘ABMTF’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Maple tree showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Maple tree.
The photograph on the first sheet is a side-by-side comparison view of a typical tree of ‘RustyAllen’ (left) and a typical tree of ‘ABMTF’ (right) grown during the summer in an outdoor nursery.
The photograph on the second sheet is a side-by-side comparison close-up view of developing leaves from a typical tree of ‘RustyAllen’ (left) and developing leaves from a typical tree of ‘ABMTF’ (right).
The photograph on the third sheet is a side-by-side comparison close-up view of developing and fully developed leaves from a typical tree of ‘RustyAllen’ (left) and developing and fully developed leaves from a typical tree of ‘ABMTF’ (right).
The photograph on the fourth sheet is a side perspective view of a typical tree of ‘RustyAllen’ grown during the autumn in an outdoor nursery.
