We have eBooks! Find more information on our Electronic Resources page.

Plant Identification Guidelines: 

Tell us where and when you saw the plant. If it was at the Gardens, tell us which garden.

Send multiple photos that clearly show:

  1. All parts of the plant (flower, leaves, bark, needles, etc.)
  2. The overall form and size of the plant
  3. A coin, pencil or shoe for scale

Tip: Hold your hand or a piece of paper behind the plant to help the camera focus on the plant rather than the background.

Collections Access

Access to the library’s collection is restricted while the library remains closed. More details about the library’s collections can be found on the library collections page.

Donations

The library accepts donations to augment our collections.

If you are looking to donate items to the library, please call or email to set up an appointment. Materials must be in good condition and fit our collection scope.

General book donations may be included in the used book sale, added to the collection or disposed of based on the needs of the library.

Donations of historical or other value are evaluated on a case by case basis. Contact us to speak with the head librarian for more information.
