Links and Resources
With the growth in the popularity of hellebores, the amount of information on the Web has grown
tremendously. Much of the information is useful, but as with all topics on the Web, plenty of it is
inaccurate as well. Here I've provided some links and resources that I believe to be for the most part
accurate, useful, and of quality.
I will add to this page as necessary. There are of course many breeders and experts in the world that
may not have business or personal websites. Gisella Schmiemann, Elizabeth Strangman, Elfi Rahr,
and Ian Collier are just a few that immediately come to mind. Fortunately, their plants are available at
least indirectly from several sources. There are also many good sites that are not listed here, many in
non-English formats. If you know of any sites that are particularly useful, please let me know:

the best hybrids in North America. Their nursery is located in Eugene, Oregon. Their plants may be

Informative Websites and Forums
Graham Rice's site is still one of the most informative in English. The information follows that in the
Rice and Strangman book The Gardener's Guide to Growing Hellebores but in several cases is more
up to date. The site is particularly useful for those interested in the history of named cultivars; it also
includes a species section and information on hellebore culture and propagation.
Gardenbuddies has one of the most active Hellebore forums on the web.
Site of one of the oldest Hellebore forums and still occasionally active.
A fairly active group with contributing members of all sorts. It also has a seed exchange every
summer, which is an added bonus.
The homepage for the Japanese Helleborus Society. Most of the information is in Japanese, but there
is also a small English section. This is a great place to browse as it contains many wonderful links to
exquisite photos of very nice hellebores.
A well-structured and informative Belgian site. Information also in English
Very interesting archives with photos. Discussions and information in Japanese.
