Cultivation Information

Information in this section is presented in 31 different tables (documents), with their organization based on the botanical classification system (taxonomy) for the Genus Penstemon.

If you have questions about cultivation please contact our Cultivation Editor at blewis@iriscolorado.com.

Taxonomy practice places each species of a plant within a genus and then into successively smaller categories based on shared characteristics of those species within a genus. The largest category of a genus is called a subgenus; following that, the categories are section and subsection. The arrangement looks like this:
 Genus
    Subgenus
      Section
        Subsection

The Genus Penstemon is divided into six subgenera. The Cultivation Tables cover four of these subgenera and all but two species neither of which has been cultivated. To get to a table, click the link as given below in the Index.
