The Mothers Day Tour of SF Native Plant Gardens is this Sunday, May 14th. It is a self-guided and free tour of 25 gardens in San Francisco that feature California native plants. For a list of gardens and descriptions, you can go to the website of the San Francisco chapter of the California Native Plant Society, at www.cnps-yerbabuena.org and go to info on the garden tour. There is a map showing the gardens, which are clustered 2 to 5 to a neighborhood, so you can just see the ones near you or range more widely. Some are public gardens, some are private. At one, the HANC Recycling Center, you will be able to buy some plants. I'll be going to some of the gardens and will report what I see.
