My first seed growing experience: I put potting soil in a flat, sprinkled the seeds on the soil. I left it on the potting table shelf which has an arbor over the top. Our sprinklers flooded the flat (oops, I forgot about that). Now there is a mess of seedlings on the ground, I don't remember what they are. No blossoms yet, but they are doing very well! Or maybe that's just wishful thinking and they are a fresh bumper crop of weeds. LOL
