Claims
I claim:
1. A new and distinct variety of Picea abies plant named
`Dougart12`, as is herein illustrated and described.
Description
Botanical classification: Picea abies (L.) H. Karst.
Varietal denomination: `Dougart12`.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct plant of Picea
abies (L.) H. Karst. (Norway spruce tree) known by the varietal
name `Dougart12`. The new variety was discovered and selected from
a group of seedlings in a cultivated area of an outdoor nursery bed
in 2000 in Wernhout, The Netherlands. As such, its parental
varieties are unknown. When compared to Picea abies variety `Will's
Zwerg` (unpatented), `Dougart12` is more symmetrical in overall
appearance, exhibits a faster growth rate, and has a smaller branch
diameter. `Dougart12` has been trial and field tested and has been
found to retain its distinctive characteristics and remain true to
type through successive propagations. The following characteristics
distinguish the new variety from other Picea abies varieties: 1.
Upright, pyramidal growth habit; 2. Compact (miniature) size; 3.
Slow growth rate; 4. Short branches and internodes; and 5. Dark
green-colored and short needles;
DESCRIPTION OF THE DRAWINGS
The accompanying photographic drawings illustrate the new variety,
with the color being as nearly true as is possible with color
illustrations of this type:
FIG. 1 shows a 3 year old plant of the new variety in a
container;
FIG. 2 shows a 4.5 year old plant of the new variety in a
container;
FIG. 3 shows an unpotted plant of the new variety;
FIG. 4 shows a close-up view of the middle portion of the new
variety;
FIG. 5 shows a close-up view of the upmost tip of the main shoot of
the new variety; and
FIG. 6 shows a close-up view of a branch of the new variety.
DESCRIPTION OF THE PLANT
The following detailed description sets forth the characteristics
of the new cultivar. The data that defines these characteristics
were collected by asexual reproductions performed via upright,
upper branch shoot cuttings in 2008 carried out in
Horstel-Riesenbeck, Germany. Plants of the new variety were grown
under natural daylight and outdoors with full sun. The color
readings and measurements were primarily taken on 4-year-old plants
grown in 7.5 liter containers. Color references are primarily to
The 2007 R.H.S. Colour Chart of The Royal Horticultural Society of
London, Fifth Edition.
