Massacre is right though, cilantro is loved by some and tastes like shit to others, through no fault of their own. I like it a lot, but my man is one of the soapy tasters, so I don't use it often.
Great job, Brian. One thing to keep in mind when planting is not to crowd the plants too much, you have to leave enough space between them for what they will grow into, use the space recommendation on the plant's info marker as a guide. You should be fine with what you have there. E.g., a zucchini plant is one that looks harmless enough to start, but can grow from a tiny stem with two leaves into a massive thing that needs 4 square feet of space. And if you ever plant mint, for the love of God don't put it in the ground, it will take over everything and its woody roots run deep and are hard to dig out - just put it in a pot and it'll be fine. Mint makes nice tea for upset stomachs.
There's something deeply satisfying about growing food, it tastes amazing. And if you deadhead those petunias they'll keep flowering all summer.
