The photographs are of a plant grown in Salinas, Calif. under greenhouse conditions. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

(2) FIG. 1 shows the overall plant habit of the plant grown in a pot.

(3) FIG. 2 shows a close-up of the mature inflorescence of the plant.

DESCRIPTION OF THE NEW VARIETY

(4) The following detailed descriptions set forth the distinctive characteristics of SAKIMP037. Data was collected on plants grown about 4 months from propagation by terminal cutting in Salinas, Calif., under greenhouse conditions, in Salinas, Calif. Color references are to The Royal Horticultural Society of London color chart (R.H.S.), 4.sup.th edition (2001). Anatomic labels are from The Cambridge Illustrated Glossary of Botanical Terms, by M. Hickey and C. King, Cambridge University Press. Classification and parentage: Family.Balsaminaceae. Botanical.Impatiens hybrida hort. Common.Impatiens. Designation.SAKIMP037. Parentage.Female Parent: Proprietary Impatiens plant line NE-4391. Male Parent: Proprietary Impatiens plant line NF-4858. Growth: Environmental conditions for plant growth.The terminal 1.0 to 1.5 inches of an actively growing stem was excised. The vegetative cuttings were propagated for five to six weeks. The base of the cuttings were dipped for 1 to 2 seconds in a 1:9 solution of DIP 'N GROW (1 solution: 9 water) root inducing solution immediately prior to sticking into the cell trays. Cuttings were stuck into plastic cell trays having 98 cells, and containing a moistened peat moss-based growing medium. The cuttings were misted with water from overhead for 10 seconds every 30 minutes until sufficient roots were formed. Rooted cuttings were transplanted and grown in 20 cm diameter plastic pots in a glass greenhouse located in Salinas, Calif. Pots contained a peat moss-based growing medium. Soluble fertilizer containing 20% nitrogen, 10% phosphorus and 20% potassium was applied once a day or every other day by overhead irrigation. Pots were top-dressed with a dry, slow release fertilizer containing 20% nitrogen, 10% phosphorus and 18% potassium. The typical average air temperature was 24 C.

(7) SAKIMP037 is a new and distinct cultivar of Impatiens owning to its compact growth habit, bright flower color, variegated leaves and strong root system. SAKIMP037 is most similar to the commercial Impatiens variety, SAKIMP005, also commercially known as SUNPATIENS Spreading Salmon (U.S. Plant Pat. No. 19,500); however, there are differences as listed in the table below:
