I should also add that the plants on my list will need to be watered
through the first summer:
about once a week until fall cools down and then once a month until the
rain starts again.

You might visit the CNPS website www.cnps.org for the chapter down
there. They might help with sources for plants. If you'd like a trip
to Chico, the Mt. Lassen Chapter is having their wildflower show and
plant sale on April 24, at the CARD (Chico Area Recreation District)
center at
545 Vallombrosa Ave from noon to 5 pm.
good luck with your project
