Syringa vulgaris L. ‘Prairie Petite’ was registered 30 Dec. 1994, by Dale T. Lindgren, University of Nebraska West Central Research & Extension Center/Horticulture, Route 4, Box 46A, North Platte, NE 69101, USA. The ortet (source plant of the clone) was originated by the late Glenn Viehmeyer about 1970 from irradiated seed of unknown parentage, selected in 1982, and named by Dale T. Lindgren. The name ‘Prairie Petite’ was registered in 1994, but publication was postponed on request. For full description and history of ‘Prairie Petite’ lilac see: Lindgren, D. T., G. Viehmeyer and R. Uhlinger. 1996. ‘Prairie Petite’ lilac. HortScience 31(1):166. ‘Prairie Petite’ has been selected for its compact, dense habit and for its potential in lilac breeding programs. ‘Prairie Petite’ lilac is scheduled for commercial introduction in August 1997 by Briggs Nurseries, 4407 Henderson Blvd., Olympia, WA 98501, USA. A standard portfolio has been opened at Royal Botanical Gardens Herbarium, Hamilton, Ontario, Canada, but is still incomplete.

At the Univ. of Nebraska West Central Research and Extension Center, the original plant of NP103 is 94 cm tall × 114 cm wide after 23 years, and several 6-year-old plants average 38 cm tall and 70 cm wide. This selection was vegetatively propagated and evaluated for 5 years at four other locations; it tended to be more vigorous at locations other than North Platte but still was considered a compact dwarf.
Leaf blades on the original parent plant in North Platte average 4.9 cm wide × 6.9 cm long, while leaves on the 6-year-old plants in North Platte averaged 4.5 cm wide × 6.2 cm long. The initial color of newly opened florets is light pink, which fades to light lavender as the florets mature [red-purple group 73D and red-purple group 69D, respectively, of the Royal Horticultural Society Colour Chart, (Royal Horticultural Society, 1966)]. Florets average 0.9 cm wide, and inflorescences average 5 cm long × 5 cm wide.
‘Prairie Petite’ is vegetatively propagated by divisions, stem cuttings, or micropropagation (tissue culture) techniques. Division is usually performed in early spring, and cuttings are taken during the spring and summer season.
This selection also has potential as parental material in lilac breeding programs. Progeny grown from open-pollinated seed collected
from ‘Prairie Petite’ have been variable in plant size in field trials at North Platte.
