This invention relates to a new and distinct variety of New Guinea Impatiens plant, known by the cultivar name Penobscot, a seedling resulting from the cross pollenation of unpatented pollen parent 77-273-1 and patented pistil parent "Mohawk" (U.S. Plant Pat. No. 4,427) and is distinguished by its medium-sized lavender flower, dark green, non-variegated foliage and pronounced spreading growth habit.

1. A new and distinct form of impatients plant as described and illustrated, known by the cultivar name Penobscot.

|||||||||||||||||||||||||
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 patented pistil parent Mohawk, U.S. Plant Pat. No. 4,427, granted June 12, 1979 and unpatented pollen parent 77-273-1, produced the distinct new variety herein described and selected for propagation by cuttings. Repeated propagations and flowerings of my new variety 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 established and transmitted through succeeding generations.
The known commercial variety to which Penobscot would be closest in characteristics is its pistil parent, Mohawk, but Penobscot is distinctly different than Mohawk in the following three characteristics:
1. The flower color of Penobscot can be described as "lavender" in comparison to Mohawk which is red-purple.
2. The foliage of Penobscot is a much darker green than that of Mohawk.
3. Penobscot has a pronounced spreading growth habit and is the most spreading plant of all the Impatiens plants that I have invented (The American Indian Series) to date.
The accompanying color photograph illustrates the overall appearance and form of the plant as well as the nature and color of its flowers and foliage; the color rendition being as nearly true as is reasonably possible to obtain by conventional photographic procedures. The photograph was taken under intensive light conditions. Under less intensive light, the flower color is slightly darker. The photograph illustrates the pronounced spreading habit of the plant which can have branches growing out at a 20° or 30° angle to the surface of the soil.
Referring to the botanical details of my new variety, the following detailed description is based on observations made on Aug. 10, 1979. All plants were grown under normal environmental conditions in greenhouses. Color readings were taken during daylight hours in full sun, and all colors are based on the Royal Horticultural Society Colour Chart.
