This paper is a report on the results of an inventory of the vascular plants at the future site of the Oklahoma Centennial Botanical Garden in Osage County, Oklahoma. We collected a total of 293 taxa in 208 genera and 68 families. The families Poaceae and Asteraceae had the greatest number of species with 50 and 44 species respectively. Forty- one species of woody plants were present. Forty-four non-native species were present, representing 15% of the flora. No species tracked by the Oklahoma Natural Heritage Inventory were present.

INTRODUCTION gently sloping to steep, loamy soils over shale and sandstone (Bourlier et al. 1979). The objective of this study was to The climate is Subtropical Humid (Cf) complete a floristic inventory at the future (Trewartha 1968). Summers are warm and site of the Oklahoma Centennial Botanical humid. Mean July temperature is 27.5oC Garden (OCBG) in southeast Osage County (81.5oF). Winters are relatively short and (36.2017°N to 36.2109°N and 96.0555°W mild with a mean January temperature of and 96.0678°W). Construction of the 1.5oC (34.7oF). Mean annual precipitation is OCBG is scheduled to begin in late 2007 on 111.7 cm (43.8 in) (Oklahoma 87 hectares (215 acres). The master plan, Climatological Survey, 2007).

Potential natural vegetation at OCBG is Mexican Garden, Oklahoma Wildflower post oak-blackjack forest and tallgrass Garden, Cross Timbers Prairie and prairie (Duck and Fletcher 1943). Historical Woodland, Folk Garden, Horticultural land use of the site has included livestock Therapy Garden, Children’s Garden, grazing and oil exploration. Demonstration Gardens, and others. In addition, a 17-acre lake, an amphitheater, a METHODS visitor center, education buildings, and a conservatory will be constructed (Oklahoma Three collection sites were visited Centennial Botanical Garden 2007). monthly for floristic sampling.
