Cultivars Of Woody Plants Abutilon

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.

Hatch's Cultivars of Woody Plants has been developed over 35 years by leading horticultural taxonomist Larry Hatch and now covers more than 2100 pages. It is the largest encyclopedia of ornamental, landscape tree, shrub, and vine varieties, most described in detail with their history, nomenclature, and landscape uses discussed. Numerous high-resolution digital images accompany the entries. This volume of 307 pages includes such major genera as Paeonia, Populus, Potentilla, Parrotia, Platanus, Pittosporum, Pieris, Philadelphus, and many others. Other volumes of genera are sold separately.

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.

This 114-page volume covers Rhamnella, Rhamnus, Rhapiolepis, Rhododendron including deciduous and evergreen azaleas, Rhus, Ribes, Robinia, Rosmarinus (over 200 cultivars), Rosam Rubus, and Ruscus. Hatch's Cultivars of Woody Plants has been developed over 35 years by leading horticultural taxonomist Larry Hatch and now covers more than 2100 pages.

This volume covers Pseudotsuga (douglas-fir), 93 different Sciadopitys, 44 Sequoia, 85 Sequoiadendron, and a shocking 353 cultivars of Taxus. This recent revision covers the "new yew" taxonomy based on recent research as well as the traditional nomenclature for the reader to chose on their own by the system's own merits and arguments. Cultivars of Woody Plants was created by taxonomist Larry Hatch to be the most complete catalog of tree, shrub, and vine varieties ever compiled. It's not just a compilation of names like so many websites. It has original research, cultivar histories, nomenclature notes, identification charts, detailed descriptions, and over 3000 high-resolution, digital images of 500-1200 pixels wide.
