Dedicated to the preservation of California's native plants

Clarkia speciosa subsp. immaculata (Pismo Clarkia)

I chose the Pismo clarkia because it grows in the area surrounding Mardi’s home and nowhere else. It grows naturally in about 20 occurrences from the southern Edna Valley, south through the foothills and valleys of the Southern San Luis Range, ending east of Pismo Beach and Arroyo Grande (Huasna Valley).

Pigs Attack the Saltmarsh of Morro Bay… again

Wild pigs are again active in Morro Bay, causing damage while rooting for the tuberous reeds in the brackish freshwater seep zones close to the high tide line. This time they are at Shark Inlet.

    The Plant Exchange is an opportunity for people to bring plants from their gardens and swap them out for something new from someone else’s garden, and we would love to have you participate with that as well. We have some people that bring several plants and others that bring just one, and the City usually contributes some plants as well as small containers and soil for re-potting.

    CNPS will host a booth at this event. If you would like participation and talk California native plants in the garden please contact Mardi Niles at mlniles@sbcglobal.net.

    If you have California native plants that you would like to donate to the exchange please come and bring your plants.
