I may be a decade or two behind the times, but the Penstemon species found on USWildflowers.com have been moved from Scrophulariaceae – the Figwort family – to Plantaginaceae – the Plantain family. The change in classification was based on genetic research done in the 1990’s, and published around the turn of the century. Wide acceptance of this classification change occurred over the next decade, but many publications have continued to list the genus in Scrophulariaceae. That oversight has now been corrected on USWildflowers.com.
