Hello. We recently moved from Zone 6 to 10 and building out a new garden is challenging after 30+ years in another zone.

We’ve had these palms planted, but the Mexican Petunias which are supposed to be iguana-proof provide a lovely meal for the iguanas on the daily.

Can you help us avoid more errors? The trellis is for jasmine. I love bougainvillea. Maybe some foundational agave and grasses? It’s 40 feet wide and shallow, about 3 feet. A pool screen will be in front of it so lush and colorful will really add to our outdoor experience. Morning through midday full sun.
Thank you in advance!
