Narrative
Specimens at the collection site in nature are represented as very large/old plants, approximately 5.0 meters in height with trunk diameters to 25.0 cm. After 15 years of growth in cultivation in central Iowa, specimens average approximately 3.5 x 3.5 meters. This species is reported to sucker, but all specimens of this accession have shown no signs of suckering while grown in cultivation. Peak fall color tends to occur during the second week in October in central Iowa ranging from reddish-orange; brownish-red, brownish-orange, etc. Acorn production tends to be consistently heavy every year and can initiate production after three years in age. Peak fruiting tends to occur between 10-20 of September in central Iowa, which is approximately 1-2 weeks prior to Q. muehlenbergii. Acorns are extremely favored by deer, rabbits, raccoons, turkeys and bluejays. Quercus prinoides in Nebraska is extremely rare. To date (2022), only two counties totalling four localities have recorded this taxa including Richardson County: two areas near Salem; one in Indian Caves State Park and one in Nemaha County described as near Nemaha. Species tends to be restricted to dry rocky upland hills and bluffs. Recent research (Hipp et al., 2019), noted that using the unweighted pair group method with arithmetic mean and non-metric multidimensional scaling ordination did not separate individuals of Q. muehlenbergii and Q. prinoides as distinct species. However, W. M. Keith Jr. (1957) states that "Q. muehlenbergii never spreads vegetatively and acorns are rarely borne until it has attained small tree size whereas Q. prinoides bears at extremely small sizes, usually a foot or so high and spreads vegetatively via rhizomes". Therefore, genetics of this accession most likely represents the hybrid of Q. prinoides x Q. muehlenbergii under the assumption that the true Q. prinoides is represented only by those that clonally spread via rhizomes. Further research is needed to clarify the identity of Q. prinoides. This accession is therefore being listed as Q. hybr. Specimens are clearly "dwarf" or shrubby in growth habit and produce acorns at extremely early ages, but do not spread via rhizomes.

  • Description Of NC7 Ornamental Trials: The NC-7 Regional Ornamental Plant Trials, began in 1954 through the efforts of a small group of dedicated horticulturists under the leadership of Professor S.A. McCrory of South Dakota State College (now University). The north central United States is a region of climatic extremes, and many parts of the region have alkaline soils that developed under grasslands. Because of these conditions, the diversity found in commercially available woody plants adapted to the area is less than that found in most other parts of our nation. The NC-7 Regional Ornamental Plant Trials were started with the ultimate goal of expanding the range of useful plants in the nursery trade. The emphasis in this program has been placed on detailed, long-term evaluations at a broad range of sites rather than on promotion of new plants. The NC-7 Trials rely on a network of horticultural cooperators located at sites scattered across the Central United States. Cooperators establish plantings, observe and evaluate the plants through the seasons, and prepare performance reports one, five, and ten years after planting. These reports are sent to the North Central Regional Plant Introduction Station (NCRPIS) in Ames, Iowa where they are recorded. Because of the broad range of environments found among the trial sites, it is unusual for any particular trial plant to perform well at a majority of the sites, making system-wide releases difficult. However, when plants perform especially well at sites, the NCRPIS Horticulturist assists trial site cooperators in introducing the new plants, with any official releases initiated through the cooperators' institutions rather than through the Plant Introduction Station.
