What is Calflora?
Calflora is 1. a website you can use to learn about plants that grow wild in California (both native plants and weeds); and 2. a nonprofit organization responsible for providing this service. Calflora is run by the team described below. Information in Calflora comes from many sources: the Consortium of California Herbaria, iNaturalist, public agencies, non-profits, scientists, private donors, and you! (A list of all data sources is available here.)
Find Out About a Plant
You can enter the common or scientific name of a plant to find out about it. Or, use the name wizard to just enter part of a name and have the wizard make suggestions. The result is an illustrated table of plants that match the name you entered. Click one of the plants in the table to learn the details about that plant — in particular, where it’s been observed in California.

by a certain person, of a certain plant, in a certain area, or during a certain time period. The application that does this is called Observation Search. The observations that match your criteria are displayed as colored icons on a Google Map. Click on an observation to see photos and other details.

We ask you to Register
No one is required pay for access to the data on Calflora. But we do ask you to register -- it helps us measure use and to improve your experience of Calflora. It also helps us when we ask foundations for support. Registering is free.
To register, click on LOGIN - REGISTER in the upper right corner of the home page, and fill out the short form. It takes a minute.
As a contributor, you can take part in another level of Calflora, which includes contributing observations, commenting on other’s observations, participating in groups, getting help with plant identification, etc. Links to applications specifically for contributors are typically shown in violet: Plant Observation Entry.
Once you register, please don’t let anyone else use your account. (When more than one person uses the same account to contribute observations, quality control becomes difficult for everyone involved.) If you need to work closely with other contributors, start a group and invite the others to join it.
Compliance Documents and Other Professional Use of Calflora
Those who use Calflora for their work to follow CEQA or NEPA guidelines, or other professional work, pay an annual service fee based on the number of users. Please contact Calflora to learn more.

For instance, if you are aware of a plant growing wild in some park or other location where it is not yet shown on Calflora, we urge you to register as a contributor and to add an observation of that plant where you know it grows.
Equally important: if you notice information on Calflora
that seems wrong or incomplete, please
