Hosta Species Update
W. George Schmid

Webwork by Bob Axmear

My book, The Genus Hosta - Zoku Giboshi (Portland, Oregon: Timber Press), was published in 1991. Considerable detailed information on Hosta species was included. Now after five printings this reference source is out of print.

In the past fifteen years, the nursery and gardening interests in hostas have grown tremendously and the many hits the Hosta Library gets show this. Also during these years there has been considerable new insight on Hosta species. This updated information needs to be made extensively and easily available to the widest audience so in this Internet day and age, I decided electronic publishing is the best way to do this.

The Hosta Library Web site is the most widely and frequently used medium for information on hostas. Mostly it concerned cultivars. Bob Axmear, the site's masterly Webmaster, and I believe Hosta Library also is the best vehicle for communicating information on Hosta species

Accordingly . . . Hosta Species Update . . . has been launched.

My plan is to pull together the latest scientific information, as well as everything else worth knowing, about Hosta species. Pictures in color many of them will be a most important part of the updates.

This project is a work in progress with no scheduled completion date. Just check in the species table below frequently for names of recently completed species. They will appear in blue and underlined as a link.

I want this feature to be interactive. Tell me what your needs are and suggest improvements. Just e-mail me at
