All I see is the basil. I'm not sure your catnip is growing. There are quite a few kinds of basil, did you plant different ones or just one kind? When it seeds, wait for the seeds to get looking sort of dry, then you can collect some to plant next year. let them dry out for a good while, don't want them to mold.
You want to plant the catnip by itself. It'll get way bigger than the basil and it will choke it out.
I love to see people take an interest in gardening.
