Policy on Sowing of Wildflowers

Adopted June 1989 (PDF Version)

CNPS is concerned that:

  • If rare species grow in the locality, closely related species should be avoided in seed mixtures.
  • Species which are susceptible to genetic swamping should be identified and use of any but local seed sources avoided for such species.
  • Locally grown seed should be increased from local wild-collected starter sources
  • Permit processes for collection must be followed.
  • Species selected should be biologically and visually appropriate; that is, they should be compatible with the surrounding wild landscape.
  • Existing native vegetation should not be replaced by wildflower plantings
