Claims
What is claimed is:
1. A new and distinct cultivar of Pinus mugo tree named `MonJaw` as
herein illustrated and described.
Description
Latin name of the genus and species: Pinus mugo.
Variety denomination: `MonJaw`.
BACKGROUND OF THE INVENTION
The new cultivar is a chance discovery in an existing population of
the unpatented variety Pinus mugo `Pumilo` seedlings, by the
inventor Richard Wells. This discovery was made in a seedling bed
at a commercial nursery in Dayton Oreg. in Spring 2012.
Asexual reproduction was first performed by grating terminal
vegetative scions onto unnamed, Pinus mugo seedling rootstock in
December 2012, at the same nursery in Dayton, Oreg. Subsequently
trials with ungrafted rooted cuttings began in 2014. `MonJaw` has
since produced additional generations and has shown that the unique
features of this cultivar are stable and reproduced true to
type.
SUMMARY OF THE INVENTION
The cultivar `MonJaw` 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 `MonJaw`. These
characteristics in combination distinguish `MonJaw` as a new and
distinct Pinus cultivar: 1. Medium sized plant growing to about
4'.times.4' at maturity. 2. Compact growth with mounding form. 3.
Maintains a bright green color throughout winter. 4. Developing
candles have an attractive brownish coloration during late
winter/early spring; especially the base of the candles. 5. Needle
length is 2-2.5 inches.
PARENTAL COMPARISON
Plants of the new cultivar `MonJaw` are similar to the parent
variety Pinus mugo `Pumilo`, unpatented, in most horticultural
characteristics. However, plants of `MonJaw` differ in the
following ways: 1. New variety has a more compact, mounding form
than the parent variety. 2. New variety maintains a more consistent
green winter color than the parent variety.
COMMERCIAL COMPARISON
Plants of the new cultivar `MonJaw` are similar to the unpatented
variety Pinus mugo `Sherwood Compact` in most horticultural
characteristics; however, plants of `MonJaw` differ in the
following ways: 1. `MonJaw` is a larger plant than `Sherwood
Compact`. 2. New variety has larger, brownish candles, while this
comparator has smaller, whitish candles. 3. New variety has longer
needles than this comparator. 4. Comparator is lower growing and
more spreading than `MonJaw`. 5. New variety maintains a bright
green color throughout winter, while this comparator has
significant yellowing in the winter.
Plants of the new cultivar `MonJaw` are also similar to the
unpatented variety Pinus mugo `Slowmound` in most horticultural
characteristics; however, plants of `MonJaw` differ in the
following ways: 1. `MonJaw` is a larger plant than `Slowmound`. 2.
New variety has brownish candles, while this comparator has whitish
candles. 3. New variety has longer needles than this
comparator.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photograph in FIG. 1 illustrates in full color a
typical plant of `MonJaw` grown outdoors in Dayton, Oreg. This
plant is approximately 4 years old.
FIG. 2 illustrates a close-up view of the foliage.
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.
DETAILED BOTANICAL DESCRIPTION
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 `MonJaw` plants grown
outdoors in Dayton, Oreg. Unless noted as values taken from a
mature plant, values are taken from a plant approximately 4 years
old, grown in a 3 liter pot. The plant has been grafted onto a
seedling of Pinus mugo. The specimen is approximately 4 years old,
grown outdoors in Dayton, Oreg. No artificial light, photoperiodic
treatments or chemical treatments were given to the plants.
Measurements and numerical values represent averages of typical
plant types. Botanical classification: Pinus mugo `MonJaw`. Age of
the plant described: Values are taken from a 4-year-old specimen,
unless noted as a mature tree measurement. Container size of the
plant described: 3 gallon commercial container.
PROPAGATION
Time to rooting: 60 to 90 days at approximately
40.degree.-50.degree. F. Root description: Woody main roots,
colored near RHS Brown 200D. Lateral roots fibrous, very well
branched, colored near RHS Grey-Brown 199A.
PLANT
Growth habit: Globular, low growing dwarf tree. Height:
Approximately 35 cm. Plant spread: Approximately 45 cm. Typical
growth rate: Moderate for species. Pinching required: No. Branching
characteristics: Single main stem with approximately 15 to 20
lateral branches emerging very low to soil line (about 3 cm).
Lateral stems have a slight curve, rather than acute angle at the
point of attachment. The angle from the main stem is approximately
45 to 80.degree. from the center of the plant. Main lateral
branches split into 3 to 4 secondary branches. Length of lateral
branches: Average 6 to 10 cm before splitting into secondary
branches. Diameter of lateral branches: Average 9 to 15 mm. Lateral
branch shape in cross section: Round. Lateral branch strength: Very
strong, moderately flexible. Lateral branch color: Near RHS Brown
200B. Lateral branch texture: Very rough, scaly. Internode length:
Average range between 1.0 and 2.0 cm. Bark: Scaly, colored near RHS
Brown 200B and Grey-Brown N199A. Candles/new growth:
Length.--Average range between 5 to 8 cm. Diameter.--Average 1.8
cm. Shape.--Cylindric. Color.--Near Greyed-Orange 175A, apical
section Grey-Brown 199D.
