Horticulture Reference Library

The Elizabeth F. Gamble Horticultural Library is a non-circulating reference library for use on-site by the public, volunteers, and horticultural staff. We are thrilled to share it with you!

To use: The collection is available in the Gamble Garden Main House during open hours 9am-2pm. Click below to access library titles through our online catalog. You may search the catalog via your laptop or iPhone at the library; or, search it from home before you visit.

Type in search words for author, title or subject and click the appropriate button. If you are not sure of the exact title or subject, type in a word or two and search both files. Press a highlighted (blue) title to see the Item’s detail page which might give more searching ideas.

Note: the catalog is not forgiving of misspellings and the search help button does not apply to Gamble.

Books are arranged in the library by an alphabetical call number system, a common classification used in colleges and specialized libraries, which is sorted by letter first and then by number. For example, QL464 comes before SB419 which is followed by SB450.

We welcome your comments and feedback on our new catalog!

Bay Area Public Gardens

The San Francisco Bay Area is rich with horticultural treasures. The following are some other public gardens worth visiting. Gamble Garden is a member of the American Public Gardens Association. Visit their web site for more information about other gardens worldwide.


The iris bed at Gamble Garden features Dykes Memorial Medal Winners from 1927 to 1968.  The Dykes Memorial Medal is awarded annually by the American Iris Society to the best iris originated and introduced in the United States or Canada.  In some years there was not a winner.  Miss Gamble would have had these medal winners in her garden as well as many others that she admired as the tall bearded iris was her favorite flower.

William Dykes was an iris breeder of the early 20th century.  While working as a schoolmaster he became one of the world’s leading authorities on irises.  He was a botanist, horticulturist, author and plant breeder, and had a deep knowledge of irises.  The British Iris Society honored him with the creation of the Dykes Medal.

Iris rhizomes need lifting every three to five years, as they become crowded and will flower less.  Lift the rhizomes after flowering, when they start making good root growth, between July and September.  Any old pieces can be snapped off and discarded.  Keep pieces about 7” long, joined to the leaves and do not trim the roots.  They then can be replanted back in prepared soil, or potted up in good soil and compost.

This summer the garden volunteers have been lifting the rhizomes from our very special collection of Dykes Medal winners, replanting them, and saving some by potting them up for sale.
