TY - JOUR T1 - An assessment of the native and invasive horticultural plants sold in the mid-Atlantic region JF - Native Plants Journal JO - NATIVE PLANTS JOURNAL SP - 74 LP - 82 DO - 10.3368/npj.21.1.74 VL - 21 IS - 1 AU - George Coombs AU - Denise Gilchrist AU - Patricia Watson Y1 - 2020/03/20 UR - http://npj.uwpress.org/content/21/1/74.abstract N2 - In 2017, Mt. Cuba Center completed a survey that assessed the diversity of plants grown by mid-Atlantic wholesale nurseries. The main objectives were to quantify the proportion of taxa (named entities) native to the Eastern Temperate Forest Eco-region (those generally marketed as native in the regional horticulture industry), as well as the number of taxa considered invasive in the mid-Atlantic. Results indicated that 25% of the total 6885 taxa are either species native to the Eastern Temperate Forest or cultivars and hybrids of those species. The vast majority of that group (77%) belong to the latter categories of cultivars and hybrids. The taxa sold through these regional nurseries represent 1368 species. Of those, 458 (33%) represent species native to the Eastern Temperate Forest. Taxa considered invasive in the mid-Atlantic region represented 4% of the total diversity. This assessment represents the first of its kind in the mid-Atlantic and will serve to inform interested parties about the current state of native and invasive plants in this region. ER -
