Abstract
A new and distinct Quercus nuttallii tree named ‘QNMTF2’ is disclosed, characterized by a unique, upright, columnal form with a dense canopy. Fall foliage is yellow, with leaves dropping cleanly in the Fall. A fast growth rate has been observed. The new variety is a Quercus tree, typically used for landscapes and gardens.
Description
Latin name of the genus and species: Quercus nuttallii.
Variety denomination: ‘QNMTF2’.
The new cultivar is a product of a planned breeding program. The new variety was discovered growing as a seedling among a group of crossbred Quercus nuttallii trees at a tree farm in Washington, Ga. The inventor made this discovery in the Summer of 2014. The exact seed and pollen parents cannot be identified.
Asexual reproduction by grafting of the new cultivar ‘QNMTF2’ was first performed during February of 2015 at a farm in Washington, Ga. The cleft grafting system developed by the inventor has resulted in progeny that have proven the characteristics of the new variety to be genetically stable. This grafting process involved taking cuttings in February, being grafted, and being placed in calloused chambers for approximately three weeks. They are then moved into 3″×6″ tree band pots and placed in humidity chambers for approximately four weeks. Furthermore, these observations have confirmed that the new variety represents a new and improved variety of Quercus nuttallii tree as particularly evidenced by the fastigiate growth habit. These genetic traits can be consistently reproduced by asexual propagation.
The cultivar ‘QNMTF2’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘QNMTF2’ grown in Washington, Ga. These characteristics in combination distinguish ‘QNMTF2’ as a new and distinct Quercus nuttallii cultivar:
- 1. Upright columnal form.
- 2. Faster growth rate.
- 3. Yellow fall foliage color.
- 4. Clean leaf drop in Fall.
- 5. Dense full canopy.
- 6. Fastigiate in structure.
- 7. Larger leaf.
The exact parent varieties cannot be identified.
Plants of the new cultivar ‘QNMTF2’ are similar to plants of Quercus nuttallii ‘QNSTG’, U.S. Plant Pat. No. 19,858, in most horticultural characteristics, however, plants of the new cultivar ‘QNMTF2’ differ in the following:
- 1. The new variety has a columnar, fastigiate growth habit, while this comparator has an upright growth habit.
- 2. The new variety has green new foliage; this comparator produces red new foliage.
- 3. Fall foliage color of the new variety is yellow; Fall foliage color of this comparator is Orange-Red and Yellow-Orange.
Plants of the new cultivar ‘QNMTF2’ are similar to plants of Quercus nuttallii ‘QNSTC’, U.S. Plant Pat. No. 16,401, in most horticultural characteristics, however, plants of the new cultivar ‘QNMTF2’ differ in the following:
- 1. The new variety has a columnar, fastigiate growth habit, while this comparator has a slightly upright to outwardly branching growth habit.
- 2. Fall foliage color of the new variety is yellow; Fall foliage color of this comparator is red.
Plants of the new cultivar ‘QNMTF2’ are similar to plants of Quercus nuttallii ‘QNSTD’, U.S. Plant Pat. No. 16,254, in most horticultural characteristics, however, plants of the new cultivar ‘QNMTF2’ differ in the following:
- 1. The new variety has a columnar, fastigiate growth habit, while this comparator has a rounded growth habit.
- 2. The new variety has green new foliage; this comparator produces red new foliage.
- 3. Fall foliage color of the new variety is yellow; Fall foliage color of this comparator is Orange-Red and Yellow-Orange.
The accompanying photograph in FIG. 1 illustrates the fastigiate growth of trees of the new variety.
Trees in FIGS. 1, 2 and 3 are approximately 3 to 5 years from planting into the field.
The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘QNMTF2’ plants grown outdoors and in a nursery in Washington, Ga. Plants are approximately 2 years old, in a 3 gallon nursery container. Temperatures ranged from 5° C. to 10° C. at night to 18° C. to 27° C. during the day. Measurements and numerical values represent averages of typical plant types.
