Soap Root (Chlorogalum sp.) is a native San Francisco Bay Area, California plant that has many uses.
Native Plants and/or Seeds
Do some research (local nurseries and gardeners, park sites, and the internet are all useful). You can consider that if a plant is native to your area you should be able to grow it easily in your environment. Plants in containers need more water than usual, and in a garden environment the plants do need more water than they would in a wild area... Counterintuitive, but true!
Use native plants as opportunities to speak with the children about ecology and the importance of providing local fauna with local flora, using examples as you see them.
