CNPS stands for California native plant society. They have chapters all over California and even in Orange County. So why should you join and attend their monthly events? Because if you are interested in California native plants, then their events are a great way to learn about California natives and connect with like minded people that are just as interested in California natives as you might be.
There are also tons of events and garden tours held by CNPS that you can attend to get ideas on what you can do with your garden. You may even make some friends.
