Penstemon digitalis species, which can be important for taxonomy. Scientists estimated the genome size for 40% of the species in the genus; using "Flow Cytometry." "Penstemon digitalis" has one of the largest genomes of the genus"Penstemon". Like other "Penstemon" species, it is used in roadside planting because it is easily grown and showy. It is recommended for easy use in gardens from the Midwest to the Atlantic coast and Pacific Northwest by the American Penstemon Society. "Iowa's Living Roadway Profiler" from the Iowa Department of Transportation says that the plant's "decorative seed capsules add interest in the fall and winter". One of
Drug discovery products have often been used as the starting point for drug discovery. Until the Renaissance, the vast majority of drugs in Western medicine were plant-derived extracts. This has resulted in a pool of information about the potential of plant species as important sources of starting materials for drug discovery. Botanical knowledge about different metabolites and hormones that are produced in different anatomical parts of the plant (e.g. roots, leaves, and flowers) are crucial for correctly identifying bioactive and pharmacological plant properties. Identifying new drugs and getting them approved for market has proved to be a stringent process due to regulations
