Plant Finder

User Guidelines

The Plant Finder is a multi-faceted tool to assist designers, contractors, maintenance personnel, community groups and the general public in selecting plants that perform well within the public right-of-way. It expands on the lists included in previous versions of the Manual and should be used in conjunction with the guidance provided in the Landscape Chapter.

The Plant Finder database is not comprehensive and there is no guarantee that these plants will survive at a specific site. All plants within the public right-of-way must be selected based on site-specific conditions and approved by the appropriate agency or agencies with jurisdiction. Download the Plant Finder User Guide for instructions on how to use the tool.

The information in this database was generated by DOT, Parks, other agency staff, and local horticulture professionals based on their first-hand knowledge as well as from existing resources. Download the Plant Finder References page for a full list of sources.
