• Answer botanical and cultural queries

To foster interest in the cultivation of Hosta and Hemerocallis, we

• Exhibit at shows

To preserve the history of Hosta and Hemerocallis, we

• Record old varieties and register them

Also, the organization has registered many hostas on behalf of several British hybridizers. Most notably, they have registered about 35 hostas produced by Eric Smith's famous Tardiana Group of blue-green hostas. Click Here to see the list of registrations by BHHS.

BHHS is a fine organization which includes members from around the world. I have been a member for several years and enjoy their Journal very much. Visit their website and consider membership.
