All-Hydrangea Taxa excluding H. macrophylla

List compiled by Peter R Smith and updated January 2010 Please note: This list is a working document and may contain errors.  An asterix after the name indicates taxa that we have been unable to locate in any gardens or nurseries and we fear many of these taxa may already be lost from cultivation HOW YOU CAN HELP US TO IMPROVE THIS LIST We would be very pleased if you could:

  • Let us know if you notice any errors in the list.
  • Let us know if you grow any of the asterix marked plants in your garden or nursery or know where they are grown, (If you could donate a spare plant that would be fantastic!)
  • Supply us with a short description for any taxa currently lacking a description or with only a very brief description.
