Lacking an active, effective international process and accomplishment in cataloging new woody plants, the OROC program serves as the only active means of 100% free communication of these new landscape plants. In our role with the assistance of Cultivar.org, we continue to seek new ornamental plants and document their traits, history, and parentage.
Mr. Hatch is the founder of Open Registration Of Cultivars (OROC)
Hatch's Cultivars of Woody Plants remains the most complete encyclopedia of tree, shrub, and vine varieties in gardens and is the 35 year work of taxonomist Larry Hatch. We are pleased to present this major improvement on woody plant references on Google Play as affordable volumes for your phone, tablet, laptop, or ebook reader.
Hatch;s Perennials is a 35 year project of taxonomist Larry Hatch to catalog and document cultivars of hardy herbaceous plants in a thorough way not done in more than 80 years by any author. With more than 1200 pages of detailed content, version 3.1 remains one of the most complete plant encyclopedias ever published.
More than 30 years ago horticultural taxonomist Larry Hatch wondered why there was no updated perennial encyclopedia with all the new cultivars from both Europe and the US as well as rarities from Asia, Australia, New Zealand, and South Africa. Not finding such a work, he created Hatch's Perennials which now spans more than 2000 pages of richly, detailed material.
