Botanical designation: Quercus nuttallii.
Cultivar denomination: ‘BETTERRED’.
The present invention relates to a new and distinct cultivar of Oak tree, botanically known as Quercus nuttallii, commercially referred to as Nuttall Oak or Red Oak and hereinafter referred to by the name ‘Betterred’.
The new Oak tree originated from an open-pollination in Oconee County, Ga. of an unnamed selection of Quercus nuttallii, not patented, as the female, or seed, parent with an unknown selection of Quercus nuttallii as the male, or pollen, parent. The new Oak tree was discovered and selected by the Inventor as a single plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Oconee County, Ga. in May, 2007.
Asexual reproduction of the new Oak tree by softwood cuttings in a controlled environment in Oconee County, Ga. since 2008 has shown that the unique features of this new Oak tree are stable and reproduced true to type in successive generations.
Trees of the new Oak 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 ‘Betterred’. These characteristics in combination distinguish ‘Betterred’ as a new and distinct Oak tree:
Trees of the new Oak can be compared to plants of the female parent selection. Trees of the new Oak differ primarily from trees of the female parent selection in branch orientation as trees of the new Oak have more upwardly sweeping lateral branches than trees of the female parent selection.
Trees of the new Oak can also be compared to plants of Quercus nuttallii ‘QNSTD’, disclosed in U.S. Plant Pat. No. 16,254. Trees of the new Oak and ‘QNSTD’ differ primarily in branch orientation and plant form as trees of the new Oak have upwardly sweeping lateral branches whereas trees of ‘QNSTD’ have laterally-orientated lateral branches.
The accompanying colored photographs illustrate the overall appearance of the new Oak 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 Oak tree.
The photographs on the first sheet comprise side perspective views of typical trees of ‘Betterred’ and ‘QNSTD’ grown during the winter in an outdoor nursery showing the differences in branch orientation and plant form.
The photograph on the second sheet comprises a side perspective view of a typical tree of ‘Betterred’ grown during the spring in an outdoor nursery.
The photograph on the third sheet is a close-up view of the upper surface of typical leaves of ‘Betterred’ grown during the spring.
The photograph on the fourth sheet is a close-up view of the lower surface of typical leaves of ‘Betterred’ grown during the spring.
The photograph on the fifth sheet is a close-up view of the upper surface of typical leaves of ‘Betterred’ grown during the summer.
The photograph on the sixth sheet is a close-up view of the lower surface of typical leaves of ‘Betterred’ grown during the summer.
The photograph on the seventh sheet is a close-up view of a typical tree of ‘Betterred’ grown during the spring in an outdoor nursery.
The photograph on the eighth sheet is a close-up view of a typical tree of ‘Betterred’ grown during the autumn in an outdoor nursery.
The photograph on the ninth sheet is a close-up view of a section of trunk of a typical tree of ‘Betterred’ grown in an outdoor nursery.
The aforementioned photographs and following observations, measurements and values describe plants grown in an outdoor nursery in Pulaski County, Ga. and under cultural practices typical of Oak tree commercial production. Trees were four years old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
