plantings along outside wall

It looks like Cordyline stricta with a gorgeous Croton!

You are right and some clivias on the bottom.

Yes, I noticed the Clivias and Impatiens below, also. :>)

It's such a beautiful landscape. I absolutely love the Croton!

This croton did not have such leaf variation as others
Most of them are more on yellow /orange side. This was mainly burgundy.

There's thousands of varieties of Crotons. I love most of them! :>)
