This is the November 2017 register of all new ornamental or landscape tree, shrub, conifer, and vine cultivar submitted or registered in the Open Registration Of Cultivars (OROC)(pronounded OH-rock) from 2013 to late 2017. OROC was formed to remedy the lack of an worldwide catalog of new cultivars because existing patent, trademark, and ICRA agencies barely account for 5% of the available new material. By reason, patented plants are only those likely to be very popular or from larger firms who can pay the free, not collector's items, most university items, nor smaller nurseries.

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.

In 2013, the New Ornamentals Society (now Cultivar.org) set about to update it's extensive files on flowering maples or Abutilon. More than 110 cultivars were described. We expected the project to yield perhaps 200-300 cultivars and be finished in six months. It turns out that this genus was far more popular in modern times and a century ago than any of the researchers realized. After nearly two years, a descriptive checklists of 525 cultivars came together to the surprise of all involved. We dug even deeper and found new images from gardens and historical scans of old catalogs that sometimes had informative illustrations. This volume is, we believe, the most complete study of the garden varieties of Abutilon ever compiled and is the product of hundreds of hours of study and travel.
