I sowed mine yesterday indoors under grow lights and will plant in the flower beds after they get bigger and acclimate them to the heat. I saved seeds from broccoli plants I had in the bed last fall that I let go to seed. I would give yours morning sun and afternoon shade until temps get a lottle cooler.

Does it get cold enough for long enough where you are? Broccoli needs cool weather.
