| Abstract: |
A new cultivar of Acer palmatum var. dissectum, `Garnet Tower`, characterized by its unique upright plant habit, it's deeply dissected and purple colored foliage, its purple stems, and its ability to be readily graphed on Acer palmatum rootstock. |
| Claim: |
I claim:
1. A new and distinct cultivar of Acer palmatum var. dissectum plant named `Garnet Tower` as herein illustrated and described. |
| Description: |
Botanical classification: Acer Palmatum var. dissectum.
Variety denomination: `Garnet Tower`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Acer palmatum var. dissectum, and will be referred to hereafter by its cultivar name, `Garnet Tower`. `Garnet Tower` is a deciduous tree grown for use as a landscape plant.
`Garnet Tower` was selected as unique primarily for its upright growth habit combined with its red foliage. The new Acer was selected in the summer of 1999 in Kurume City, Kyushu, Japan as a naturally occurring branch sport of Acer palmatum var. dissectum `Garnet` (not patented).
Asexual reproduction of the new cultivar was first accomplished by grafting onto Acer palmatum rootstock in March 2000 in Kurume City, Kyushu, Japan. The characteristics of this cultivar have been determined to be stable and are reproduced trueto type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the characteristics of the new cultivar as observed for ten years in Kurume City, Japan and for three years in a test garden in Atlanta, Ga. These attributes in combinationdistinguish `Garnet Tower` as a unique cultivar of Acer palmatum var. dissectum. 1. `Garnet Tower` has a unique upright growth habit. The species, Acer palmatum var. dissectum have branches with a weeping habit. 2. The palmate foliage is dissectedand primarily purple in color. 3. The stem color of `Garnet Tower` is green with a overlay of purple that intensifies with sun exposure and in fall. 4. `Garnet Tower` is readily grafted onto Acer palmatum rootstock.
In comparison to the parent plant, Acer palmatum var. dissectum `Garnet`, `Garnet Tower` was an upright habit, whereas `Garnet` with similar foliage coloration, has a weeping plant habit as is typical for species. `Garnet Tower` can also becompared to Acer palmatum var. dissectum `Lionheart` (not patented). `Lionheart` is similar to `Garnet Tower` in that it has red foliage and an upright habit, however unlike `Garnet Tower`, the habit becomes weeping as the tree matures.
BRIEFDESCRIPTION OF THE DRAWING
The accompanying colored photographs of `Garnet Tower` illustrate the overall appearance and distinct characteristics of the new Acer palmatum var. dissectum.
FIG. 1 was taken of a ten year-old plant of `Garnet Tower` as grown in Kurume City, Japan and provides a view of the plant habit of a mature plant.
FIG. 2 provides a close-up view of the upper surface of a leaf.
The colors in the photographs are as close as possible with the digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Acer palmatum var. dissectum.
DETAILED BOTANICAL DESCRIPTION
The following is a detailed description of the new cultivar as grown outdoors for ten years in Kurume City, Japan and in a trial garden in Atlanta, Ga. for three years. The phenotype of the new cultivar may with variations in environmental,climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with the 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except wheregeneral color terms of ordinary dictionary significance are used.
