Hardy herbaceous perennials make up a major part of our gardens in the world. For mostly political reasons, there is no formal process for cataloging or registering new varieties or cultivars of these important plants which sell in the billions per year. In 2013, the Open Registration Of Cultivars (OROC) aka "Oh-rock" program was created to provide a worldwide guide to new hardy herbaceous plants. This Fall 2018 edition provides 77 pages of plant descriptions, images, and links to buy to study the new plants in the public interest. It is 100% free.
