California? I hear your state has the most awesome native plant group! I've saw that California Native Plant Society has been posting videos on YouTube for years. I wish CNPS would post them all.

But where I live not all the Native Plant Society of Texas chapters share theirs online. Out state NPSOT posts videos separately from the chapters. They are all great. I wish we had recordings from the last 40 years; so many unique presentations with information not available anywhere else.

That is a great thing about the many chapters. Texas has 12 EPA Level 3 ecoregions, and so the chapters provide information specific to their areas.

You have ecoregion diversity in California, too; and so the different affiliates of CNPS probably provide so much benefit.
