I wanna plant like a green plant and then a flower plant pattern straight across my front yard.

I like the green pant that’s on the bottom of the pic does anyone know them name? Or any other ideas that are similar and simple to care for.

Here is kinda what I want. A flower plant/green plant pattern going straight across the front of our home. Not this crowed tho but anyone know what flower this is? The purple one or any other ideas? I want two diff plants that are very easy to maintain that why they aren’t dying lol.
