Will it look like this again?

Hey, fairly new to this gardening lark, last year I built a raised bed, planted some perennial plants and by July it looked like the picture, I was pleased with it.

As of now the raised bed is covered in forget me nots where most of this plants left of the Cordyline are, so my question is will the plants that were there last year come back with the forget me nots there or shall I pull them up (despite them looking great)

Granted it’s not July yet and I probably need to be patient.
