Hi and welcome - as Alice points out, we really need to know a little bit closer as to where you are - at least if you could add your city, we'd have a better idea of your climate. Near the coast is much different than inland for example.
The north sides of the houses here are a challenge. In winter the house shades the beds and it can be quite a bit colder there than other garden areas where the sun warms the ground during the day. But then in summer when the sun is straight up overhead, you have full sun all day.
This is what I'm thinking about the bed in your picture to the left of the walkway - all shade all day in the cold months, all sun all day in the hot months. Different types of plants are needed for those two situations.
Two things you can do - first is to just plant annuals that like the cool weather in there for some nice color through the winter months, but plant the bed mainly with tropical perennial plants that will be dormant in winter.
Second thought is to plant another clump of the Adonidia palms like the ones on the other side of the walkway. They will then shade the bed equally, cooling things off substantially in summer. Then you can put in plants that do well in shade all year.
Let us know where you are and what you think about these ideas, and we can then recommend some more plants for you.
