| Abstract: |
This invention relates to a new and distinct variety of New Guinea Impatiens plant, known by the cultivar name Chinook, a seedling resulting from the cross pollenation of unpatented pollen parent 76-73-1 and unpatented pistil parent 76-201-1 and is distinguished by its spreading growth habit; many small, slightly cupped, lightly candy-striped red-purple flowers; and very dark, reddish green, metallic looking (black-green with a dull shine) non-variegated foliage. |
| Claim: |
I claim:
1. A new and distinct form of Impatiens plant as described and illustrated, known by the cultivar name Chinook. |
| Description: |
BACKGROUND OFTHE INVENTION
The present new variety (seedling) was discovered by me in a commercial greenhouse in Fremont, Calif., as a result of a definite breeding program to produce improved and different commercial varieties of plants.
The cross pollenation of unpatented pistil parent 76-201-1 and the unpatented pollen parent 76-73-1 produced the distinct new variety herein described and selected for propagation by cuttings. Repeated propagations and flowerings of my newvariety through asexual reproduction by terminal or stem cuttings grown in pots in a plastic (polyethylene) greenhouse in Fremont, Calif., under normal environmental conditions show that the characteristics described come true to form and are establishedand transmitted through succeeding generations.
BRIEF SUMMARY
The known commercial variety to which Chinook would be closest in characteristics is Aztec, U.S. Plant Pat. No. 4,193, granted Jan. 17, 1978. Chinook is much like Aztec in growth habit (spreading) and flower form (Many small, slightly cupped)but distinctly different in the following ways:
1. The foliage of Aztec is variegated whereas the foliage of Chinook is not variegated under greenhouse growing conditions,
2. The color of the foliage is very dark reddish-green and can be described as looking almost metallic (black-green with a dull shine),
3. The flower of Aztec is not candy striped, whereas the flower of Chinook is lightly candy striped,
4. The flower color is red-purple and could be described as red-plum in color,
5. A spreading growth habit, but Chinook has shorter internodes than Aztec.
DESCRIPTION OF THE PHOTOGRAPH
This new variety of Impatiens plant is illustrated by the accompanying photograph which is a close-up view of the foliage and flowers and illustrates the color of the flowers as nearly true as is reasonably possible to obtain by conventionalphotographic procedures.
DETAILED DESCRIPTION
Referring to the botanical details of my new variety, the following detailed description is based on observations made on Mar. 10, 1980. All plants were grown under normal environmental conditions in greenhouses. Color readings were takenduring daylight hours in full sun, and all colors are based on the Royal Horticultural Society Colour Chart.
I. PLANT
Name: Chinook
Origin: Seedling of the cross-pollenation of the unpatented pistil parent 76-201-1 and the unpatented pollen parent 76-73-1.

Borne: End of branches, terminal.
Blooming habit:
1. Relative number.--Many.
2. Time to flowering.--Short.
3. Longevity.--3 to 5 days.
Size of mature flower: First flower on a plant may be small.
______________________________________ 1. Length.--5.0 cm. Varies little, 2. Width.--5.0 cm. 3. Spur.--5.5 cm. slightly cupped ______________________________________
