Today we went to Floral Native Nursery in Chico and I bought native plants, which I planted in Susan's back yard. The locally native plants I bought are California coffeeberry (Rhamnus californica), California grape (Vitis californica), deer grass (Muhlenbergia rigens), monkey flower (Mimulus puniceus), and coyote mint (Monardella villosa). The plants I bought that are native to other parts of California are golden currant (Ribes aureum), California fuchsia (Epilobium californicum), interior California buckwheat (Eriogonum fasciculatum), and blue flax (Linum lewisii). The monkey flower, coyote mint, fuchsia, and buckwheat are all in bloom right now. The currant seems to have lost some of its leaves during the truck ride back to Susan's duplex, so I hope it recovers.
Susan bought a second aquarium, just in time for the daddy convict fish and several of his babies to mysteriously die, leaving few enough fish that they all fit comfortably in a single aquarium now. I think we're going to fill the other aquarium with better behaved, less violent fish instead of with cichlids. Some tetras would be nice.
