Plant Identification Service

The Hyde Herbarium provides free plant identification to the public. To have a plant identified, please bring in a sample with either flowers or fruit to the herbarium. If your sample does not have flowers or fruit, we will try to identify the plant, but may not be able to accurately identify its species.

If possible, please bring your sample during our open hours. Otherwise, you may also drop off plant samples for identification at the Center for Urban Horticulture reception desk.

We are most likely to identify your plant if you bring in a fresh sample. But if need be, you may email us photos and a description of the plant and its growing conditions at

To mail a plant sample to the Hyde Herbarium, please fill out a plant identification form and mail to:

The Hyde Herbarium also assists students, faculty and staff with plant identification and plant keying. Herbarium staff can guide those with questions to appropriate resources and help navigate the collection of herbarium specimens.

Students and researchers are also encouraged to submit voucher specimens from their research to the Hyde Herbarium. Doing so creates a permanent record of the plant researched that becomes part of our main collection. The herbarium will process the plant specimens and provide long-term care to voucher specimens. For information on collecting and making voucher specimens, please contact the Collections Manager at or (206) 685-2589.
