Maryland’s Best Native Plant Program
A cultivar is a plant variety produced in cultivation by selective breeding for specific traits such as dwarf size or disease resistance. The cultivar name is designated within single quotes such as Juniperus virginiana ‘Gray Owl’. Many of the recommended species have cultivars for you to choose from, but be aware that there are some pros and cons to using cultivars of native plants.
