CNPLX uses the CalFlora database but presents the information in a different way from CalFlora. Native plants can be searched by county (rather than by specific address) and by several other criteria such as type (tree, annual, etc.) and family. For each plant that grows wild in California, there is a plant information page that shows nurseries and seed vendors that sell the plant and information about growing the plant. This site is less useful for selecting appropriate plants for a particular site than CalScape or CalFlora, but its online inventory of nurseries that sell particular plants is well laid-out. And it’s good for identifying what particular plants are native to Marin County.
