Recommended nurseries to visit close to Orange County, CA

[Vonnie]

Hi, I'm visiting the Orange County area for the first time and I'd love to stop in somewhere to just have a look.
I wouldn't be able to purchase anything since I can't take them back on the plane, but I'd still like to look around!

We have rented a vehicle, but I'm not comfortable driving in the area and I don't think they'd want to go too far out of the way for me to "just look at some plants", hahaha. The closer, the better! Anything further than 2 hours away might be too much.
