<i>Nyssa </i>tree named ‘BBN-01’

Abstract

A new and distinct cultivar of Nyssa tree named ‘BBN-01’, characterized by its broadly ovate tree form with outwardly branching habit; vigorous growth habit; upright central leader with relatively large caliper and numerous lateral branches providing a full and densely foliated appearance; large glossy dark green-colored leaves that are initially deep red when developing and becoming dark green during the summer and turning reddish orange, red and dark red in color during the autumn; and green-colored leaf petioles variably tinged with dark red.

Claims

1. A new and distinct Nyssa tree named ‘BBN-01’ as illustrated and described.

Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying colored photographs illustrate the overall appearance of the new Nyssa 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 Nyssa tree.

(2) The photograph on the first sheet is a side perspective view of typical trees of ‘BBN-01’ grown during the early summer in an outdoor nursery.

(3) The photograph on the second sheet is a close-up view of leaves of a typical tree of ‘BBN-01’ grown during the late spring.

DETAILED BOTANICAL DESCRIPTION

(4) The aforementioned photographs and following observations, measurements and values describe trees grown in 7-gallon containers in outdoor nurseries in Park Hill, Okla. and Fort Worth, Tex. and under cultural practices typical of commercial Nyssa tree production. Trees used in the photographs and description were three years old. During the production of the trees, day temperatures averaged 33° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
