Her artistic method involved a disciplined blend of calligraphy and music alongside botanical study. In works like The Ballad of Santa Zita, she surrounded her handwritten text with accurate depictions of local flora such as lilies and thistles. These illustrations are defined by fine line work and a lack of unnecessary ornamentation. She often included the musical notation for the songs she collected, creating a clear document on a single page.

Modern collectors value Alexander for her ability to merge graphic design with natural history. Her prints offer a structured yet organic aesthetic that suits contemporary interiors. The combination of historical script and botanical detail provides a sense of quietude. These works function as art and historical documents, bringing the specific character of the nineteenth-century Italian countryside into a room.
