Every seed has sprouted

I ordered 5 packs and wasn't expecting many of them to sprout because it's my first time growing flowers that aren't marigolds in a disposable cup ūüėÖ. I planted 4 packs. I have 40 sprouts in my garden. I feel like I lucked out! Now I have the problem of moving the flowers further apart before they get too big lol.
