Version 1.2
Last update: 10.26.2014

This new tool gives you quick, single password access to PDF cultivar checklists and full genera treatments from part of Cultivars of Woody Plants, Hatch's Perennials, NODgeo, HITS, Pinetum Novum, Pauli, and other projects from within the New Ornamentals Society family. This system is designed for libraries, both corporate and institutional, to have immediate, multi-platform access to recent, original research from the New Ornamentals Society, work that now spans more than 35 years and over 112 expert contributors. The content ranges from over 6.5 gigabytes of plant enyclopedia content with more than 4700 high-res, digital images. Our focus in ornamental, landscape plants only but we cover all the indoor and outdoor plant groups in one package.

What computers or devices does it work from?

Anything that displays the website GENUS CENTRAL™ (ordinary internet HTML) and can display PDF files. That was 421 different computers, phones, tablets, book readers, PDAs, netbooks, laptops, and other devices at our last check. We have tested it on more than 38 popular devices to date. There is an internet reader and PDF reader for almost everything out there. Many of our users will use CULTIVAR.ORG DIRECT ACCESS from their iPhone or Droid, favorite tablet, and home computer on the same day.

If you need a free PDF please click this link.

How long is the subscription?
You can access the PDF files by clicking CULTIVAR.ORG DIRECT ACCESS logos and entering your password for as long as you wish up to 2018. If you are happy with the original files, you do not need to renew unless you want the next year's updates and new files.

And after 2018? You would be required to subscribe again as those passwords and links will be removed. If you downloaded the PDF to your can of course access those anytime as we do not "poison pill" them to expire. Like regular bought it, you keep it! Your menu access will stop after 2018 unless you renew but the files you save to your local computer or device are yours to view.

Do I get updated information?
Yes and that is why the New Ornamentals Society databases have been the "go to" references since 1993 because the web allows very quick, highly affordable, and unlimited space for updates to plant data. Your subscription includes the core datafiles active and live until 2018 and also a way to get to your current year updates for 2015, 2016, 2017, and 2018. You get updates only during the year you subscribe.

If you want all the updates, new ones every single year, a new subscription or renewel each year is needed. For example, if you are happy with your core files and updates, you may elect to renew some years later. If you want all the new research, updated genera files, new cultivar checklists, and updated content

You set the subscription frequency: every year, every few years, once one time, or let me decide later.

The free links and updates are available to anyone, anytime regardless of subscription by going to GENUS CENTRAL.

Yes, it is 90% the same as NORL 2 (the full library) but it's a much-enhanced platform with many advantages. First of all, every plant genus is on one download page. We also have added hundreds of free content items from around the web (Youtube video embeds, free online articles, cultivar checklists from experts, plant society resources, HortScience cultivar releases, nursery source links, collection lists, research notes, and many other topics). CULTIVAR.ORG DIRECT ACCESS lets you pull up the PDF file for all plants with a single password any time and any place. There are many updated files too since NORL 1 and 2 were offered.

Can I buy this system on a DVD or thumb-drive?
No. Sorry. We want to be sure you see and get all the content fresh and live. We did thumbdrives for a time but found a disturbing number of them did not make it through customs worldwide and even in the Americas! If we did a DVD it would need to be remastered every week or two and that expense would cut our research funding to unacceptable levels.

How does the data get to my phone or tablet?
Two ways and you can choose your method at any time. And you can mix and match. You can load the GENUS CENTRAL menu and download the PDF fresh then and there - live. Or you are free to download the entire PDF (all of them in fact, all 6.5 gigs) to your devices storage/chip/hard drive for even faster loading. Many of us, save the files to disk/storage we use often and then go live to the internet to view the other ones. You get to download and keep those files for all long as you care to store them.

And people often ask how I know which files are new to download them? Very simple, new content is marked in dark red with white letters so scrolling down GENUS CENTRAL makes them easy to spot. Also, major updates are described in our NEW FILE section of the first menu page, usually calling attention to major new cultivar checklilsts.

Is this for one user or more?
Each subscription is for one user (or in the case of a library, one patron workstation) in a single building. Each separate building requires a separate license. The user may use it on one device at a time but you will find it very ease to switch among a tablet, phone, desktop computer, laptop, and ebook readers without any special codes or fuss. Multiple users require more than one subscription. Please write to ornamentals @ if you would like a discount on 10 or more subscribers/buildings. The 1 to 9 users rate is the same.

Can I share it with my students or clients and have them download files?
No. That is a copyright violation. You can use it in a university or botanical library setting but each user in a classroom, class, or consulting situation each user must have a separate license. We do offer educational discounts with a minimum order of 10 licenses and will be glad to quote a figure for your needs.

Do we get anything else?
Yes and those will usually be surprises in terms of the occasional ebook or useful reference. One benefit is BIOH (Biographies in Ornamental Horticulture), a very detailed and becoming complete set of files on the people who made our landscapes richer, more pleasing, and refined by their plant exploration, selection, breeding, and distribution work. People often refer to BIOH as the "Who's Hoo whom is maybe Who or Whom" (we can't use the trademarked name here!) of ornamental, landscape horticulture pioneers and genius experts. You will love it and maybe you belong there too...?

You also get occasional horticultural ebooks at no extra charge.

While CULTIVAR.ORG DIRECT ACCESS does not make you a member of the International Coleus Society (ICS)(, you do get access to their full database (ICS CULTIVAR FILES) of more than 1450 named Coleus (formerly Solenostemon) cultivars with long, detailed descriptions to cultivars from 1850 to present, lavishing illustrating with screen-wide digital images as well as historical old artwork, catalog scans, and more.

What will I receive?
We post nor mail anything. It is not printed or on a disk of any kind. It is all online, digital, and live. No tangible book nor journal is sent - just to be clear. This is 100% online, digital delivery or basically giving you passwords to access the existing GENUS CENTRAL content via the CULTIVAR.ORG DIRECT ACCESS and other buttons. Your PDF files are quickly downloadable with just that one click...hence DIRECT ACCESS.

Can I use this system offline such as when my wi-fi connection is not available?
Yes and we designed our system for just that reason. Gardens and rural nurseries are not always easy wi-fi spots. Even if you cannot get a live internet feed to our GENUS CENTRAL menu, you can download your PDF files to your device(s) in advance and just load the PDF from your local software reader. If you device does not support all 6.5 gigs of content, you may want to consider using alternate storage media or downloading on a smaller subset of the files. Obviously, if you have a regular laptop or powerful tablet, 6.5 gigs is not going to be an issue.

Got a question we did not cover?  Please scroll down below and if that material still doesn't help, please email us at ornamentals @ and specifically ask about CULTIVAR.ORG DIRECT ACCESS. Please be very specific in your questions.

  1. Portability: even with the finest set of horticultural manuals, none of us is going to haul them around the nursery, garden, greenhouse, or classroom. CULTIVAR.ORG DIRECT ACCESS gives us 6.5 gigs of solid, reliable, time-tested, expert-reviewed plant data anywhere we go with our portable devices. 
  2. More (and better) cultivars: we have more cultivars than EVERYONE ELSE IN ANY MEDIUM for 92 different ornamental plant genera compared to the famous guru and society encyclopedias - sometimes three to twenty times what they have. We love their insights and comments but being complete, super-detailed, exhaustive, and comprehensive is something their publishers will never permit. It's a bottom line, bean-counter, extra pages kill profit, data limit thing. We are digital, full bandwidth paid - no limits here. Do you know anyone else describing 712 cultivar of Juniperus, 235 Haworthia,187 Lirope and Ophiopogon, 197 Ginkgo, 159 Aucuba, and 164 hardy herbaceous Hibiscus?
  3. Better data: We uise 141 different data fields (not on every plant by any means) and we can describe the living heck out of a cultivar if we can measure it or read a nice patent application. We give as much data as we know about and being digital we have no publisher telling us to wrap it all up in 300 pages. We often provide web links for academic articles or a nursery fact sheet to read more about a cultivar; thought we usually distill it's facts on your PDF already.
  4. Expert reviewers: We have many of the great experts in a genus assist us with proofing and even creating our major cultivar checklists. All files posted are reviewed by a trained horticultural taxonomist for nomenclatural accuracy. CULTIVAR.ORG DIRECT ACCESS is not a "pooled ignorance" garden website where any fool  can post away with bad names, photos of the entirely wrong genus, and rename something  for their pet poodle that already has a legit name. Our data are checked, filtered, reviewed, and in the rare event we make a is corrected right away.
  5. Click to buy (nursery sources):  we are NOT a source guide to common cultivars but we go to great lengths to provide clickable web links to sources for new and sometimes very rare cultivars we think our readership just might want to pick up. Some of these are sources not widely known  and open up a new world of plant collecting for ourselves and our users.
  6. Exclusive data - original research: since 1992 the New Ornamentals Society has sponsored over 110 research projects to construct very complete, original cultivar checklists (with descriptions and more than 4700 images) based on new research by staff and members. We consult with experts who rarely if ever publish and work almost only with us. We have broken many stories about cultivar histories and other garden history mysteries.
  7. All major ornamental plant groups: we pretty much cover it all with one subscription: trees, shrubs, vines, conifers, herbaceous perennials, biennials, bulbs, corms, tubers, other geophytes, annual-bedding plants, tropical and interior (house) plants, and ferns. If it's ornamental and can be used in some type of indoor or outdoor landscape, we have it.
  8. Price: no other reference system provides this much quality, high-detailed plant data for this low price. Because you download the files (either live or directly on your devices storage, your choice), we can offer more information compared to print and DVD media publishers. 
  9. Better photos: when we first posted 1000 pixel wide images from our digital cameras in 2002 (New Plant Page), people thought we were nuts. No one wants to see big pictures when tiny thumbnail-style images are what most sites have, some said! Most folks were amazed at what could be done. Others said our bandwidth costs to host big pictures would bankrupt us. None of the bad things happened and folks got used to amazing, colorful, and actually helpful plant pictures that filled their screens up to 1250 pixels wide.Now we have more than 4700 of them online and handy in PDF files for easier sharing and loading.
  10. Everything in one place: when the New Ornamentals Society was founded in 1992, one of our goals was "everything in one place" in terms of landscape plant cultivar data. Early on that meant plant names, their descriptions, histories, identification of cultivars and species, literature references, an internet link to a nursery or two, and lots of cool photos. As we and the web got more sophisticated we grew to put videos, audio files, web links to academic articles, plant society resources, external photo links, plant patent files, collection lists, new cultivar releases (academic, private, and commercial), database search tools, cultivar spreadsheets/databases, International Cultivar Registration Authority checklists and files, university and plant society trial reports, and so much more. Unlike web search engines we edit the whole watery stew down to the meaty, rich content.
  11. Upgrades this year:  does your favorite manual by that  famous guru or legendary nursery send you updates or supplements throughout the year? The publisher and author will take our money and run. They are done. End of data. Case closed. No new plants and definately no new valuable web links or practical research findings. We maintain an obligation to you, work hard to produce new content every single month and will even adopt your additions and corrections that you and thousands of other subscribers send us.
  12. International nomenclature standard: We have no fault if one goes to the guru manuals or those royal folks as your nomenclature standard but consider a couple of things please. Those references were outdated the second they went to print and most of them have no clue what new plants are on the American market this year or next. Often not even the new cultivars offered in Europe or Asia that we tell you about. Even one very famous plant society very often gets patented and trademarked stuff wrong - and violating a registered trademark or patent because you think it's a free cultivar is very bad business and might be a costly mistake. Curators and collectors around the world use our resources and even help us when it comes to revisions and updates. We are frequently cited in both journal articles and plant accession databases as the source for names.

You get all these libraries or reference collections with your CULTIVAR.ORG DIRECT ACCESS package. In the past, this entire library cost as much as $219 for a one year password. Now you may a hundred less and have multi-year access.

HATCH'S CULTIVARS OF WOODY PLANTS (CWP) is the product of more than 38 years of research by world-renowned horticultural taonomist Larry Hatch and is the most complete encyclopedia of tree, shrub, and vine cultivars ever produced. We like the popular tree and shrub manuals but in most cases we describe and illustrate in 1000-1250 pixel color images about three to twenty times the cultivars. CWP is widely regarded as the most complete encyclopedia of tree, shrub, and vine cultivars ever written. "I didn't know I was missing so much" is what we often hear from collectors who were depending on far smaller references.

CWP not only offers detailed descriptions but includes individual cultivar histories, literature references, selected clickable nursery links (new cultivars), and identification charts and keys based on original research. The monograph THE REDBUDS is included and covers over 91 taxa of Cercis. Cultivar counts include 59 Abelia, 1031 Acer, 159 Aucuba, 207 Buddleia, 31 Clethra, 188 Cornus kousa, 109 Fagus, 103 Ginkgo, 60 Nandina., and 224 Viburnum.

PINETUM NOVUM is the most complete portable PDF Conifer Encyclopedia ever written and is the product of more than four decades of years devoted to conifer research.

Why would we need another conifer encyclopedia? Because this one is the most complete for many genera including 207 cultivars (298 names) in
Cryptomeria, 41 Metasequoia, 93  Sciadopitys cultivars (by far a new record), 44 Sequoia, 85 Sequoiadendron, more than 400 Thuja/Platycladus, 354 Taxus, and more than 687 Juniperus cultivars. For starters we have 27% more cultivars than the recent RHS Encyclopedia of Conifers. PINETUM NOVUM is portable in PDF so it goes on just about every phone, tablet, book reader, netbook, laptop, desktop, or other device you haveOur section on Juniperus virginana and J. scopulorum alone is 75 pages of 8 x 10 size. Our Pinus cultivar section is 60.2 megabytes (in three download-friendly volumes) so many are the descriptions and photos. Our original research has solved dozens of long-standing mysteries in cultivar identification and history of fine conifers around the world. We were the first in years to show the real Pinus strobus 'Contorta', proving it's modern imposter is very wrong and different. We also proved Berckman had not two but three different golden oriental arbovitae and proved it with his own articles and advertisements; showing exactly how the modern nomenclature is incorrect. You will not find 1000-1250 pixel-wide, screen-filling images in those other references.

PINETUM NOVUM is not just a listing of names with links to Google images or tiny thumbnails which provide virtually no definitive information. It is not a simple checklist because 97% of the named taxa are described in rich detail and with Mr. Hatch's attention to nomenclature as a much respected Horticultural Taxonomist. Being PDF portable, this amazing reference can go with us to the nursery, garden center, garden/arboretum, or client's home. This offer includes the GARDEN JUNPERS monograph.

HATCH'S PERENNIALS is based on PDF format so can be loaded on your phone, tablet, book reader, netbook, laptop, and any computer for taking with you everywhere plants are found. But this is not just an ultra-portable reference but it contains huge, high-res digital of 700-1250 pixels wide.  HP 3.0 has more cultivars than other leading perennial guides, including 177 Achillea, 192 Agapanthus, 70 Agastache, 109 Ajuga, 254 Canna, 52 Colocasia, 103 Echinacea, 115 Epimedium, 115 Epimedium, 900+ Hosta, 28 Juncus, 118 Miscanthus, 125 Monarda, 766 Phlox, 365 Salvia, 226 Sedum, and 57 Tricyrtis - all of these names verified and carefully documented by a leading horticultural taxonomist.

HP 3.0 already has more than 900 Hosta cultivars including massive images 1000-1250 pixels wide available. The HOSTA ONE™ project is expanding that one PDF file even more to be the best, single volume, portable and digital reference we can produce.

An excel format spreadsheet/database covering the best 2000 African violets from around the world. Why use Pauli? It's regularly updated, has registered and unregistered cultivars, and is reviewed by a horticulturist taxonomist and Saintpaulia experts for accuracy. It is the ONLY AFRICAN VIOLET DATAFILE ANYWHERE that works on PC and Mac platforms, any laptop, netbook, Blackberry, nook, Kindle, Sony Bookreader, Palm, iPad, "clouds" like Google Fusion Tables, Google Docs, and nearly any phone including iPhone and Droid. You can modify it many ways for your projects including trade, sale, want, show, and collection lists. Now your AV data goes everywhere you and your plants  go!

NODGeo is a wonderfully diverse set of enyclopedic files as well as searchable and sortable spreadsheet/databases to be best cultivars new and old in many genera. And yes we do have hundreds of heirloom bulbs! Our research is original and our descriptive cultivar checklists are among the best ever.

First we start with the basic Bulb Module with hundreds of basic, general bulbs in many genera for easy selection. This is one of the oldest (yet revised) bulb databases and was sold widely in the 1990's as the BULB MODULE of the PLANT DATABASES LIBRARY for IBM PC compatible computers, breaking ground in geophyte plant selection.

We have since expanded some genera such as the NOS CANNA CULTIVAR CHECKLIST PROJECT with amazing Canna history and more than 450 cultivars (nearly all described) from around the world.

Gladiolus too deserved it's own database and so the NOS GLADIOLUS CULTIVAR CHECKLIST was born in spreadsheet form to allow very quick selection

DB-LILIUM soon came about and includes very detailed selection and sorting b name, cultivar group, height, flower color, and more. There description field is very detailed as this genus is hard to code without using lots of specific terms and subtle nuances.

TULIPA-DB joined the NODGeo family in 2011 and allows selection of cultivars and provides a very robust, flexible reference tool.

An affordable 400+ page preview of the big, bad, mega-reference on interior plants coming in 2018
HITS: EARLY PREVIEW EDITION is your best guide ever to house, interior, tropical, and succulent plants before the much awaited completion of this massive 1100+ page work in 2018. It has been 30 years since A.B. Graf wrote his amazing Exotica and there are thousands of cultivars that have arrived since. We cannot begin to compete with the great Mr. Graf but the world does need an update to use alongside his world-changing reference.

Why buy early? Because nothing in any medium can touch the depth of research offered in our 2013-15 preview. You will also have exclusive access to comment on the contents and submit any changes or additions to our scientific editors - and we know many of you asking about this work are experts in more than one genus. Thirdly, the new early view edition has material available before to society members. Your subscription price will be added 100% to the research fund to complete the remaining pages. Inorder to complete the project, the editors have all agreed to defer their royalties until completion in 2017.

For more background on the unfolding HITS project, some of it's imaging advances and goals please visit this page:

When we began the HITS project, we knew that the genus Coleus was going to need some tackling and rework as one immensely popular Coleus database and about 12 of the leading plant vendors were no longer in operation. COLEUS CENTRAL™ was built over three years from our existing, fairly full files and this ended up spinning off into the new INTERNATIONAL COLEUS SOCIETY (, now producing a vast 1450+ cultivar encyclopedia with some of the best ever pictures in this genus. CULTIVAR.ORG DIRECT ACCESS members are not ICS members but by special arrangement you do get their entire ICS CULTIVAR FILES archives which as of today on 30 October 2014 was a whopping 113.6 megabytes in PDF. Click here for a nice sample of Coleus Cultivars A to C.

NOD Annual Bedding Plants is back. Because of popular demand from both home gardeners, a couple of very famous botanical gardens, and some bedding plant experts, we are updating the NODabp system and bringing back our colorful galleries and very interesting cultivar lists.
