The Jepson Horticultural Database derives from the horticulture information provided in the first edition of The Jepson Manual for more than 3500 native species. The database is intended to allow this information to be searched easily and maintained conveniently. It will be expanded to allow searches that include other characteristics of the plants.

The Jepson Herbarium gratefully acknowledges the Elvenia J. Slosson Endowment Fund for supporting the development of the Jepson Horticultural Database.
