Pansies don’t like heat—preferring the cool spring and fall temperatures; they often fade in summer. But in general, you can start pansies indoors about 6 to 8 weeks before transplanting outdoors. Keep up with deadheading, watering, and place in partial shade if you live in an area with hot summers, to try to keep the plant going until cooler weather sets in. If these are to be wedding favors, or in a flower arrangement, you might try growing them completely indoors as houseplants in order to try to maintain that cooler temperature (daytime around 70F; nighttime between 55 and 65F) — indirect sunlight, but lots of it. They take about 7 to 14 days to germinate, and then about 65 to 85 days to bloom — so about 72 to 99 days total — check the days to germination, and days to maturity/bloom on the seed packet for your particular cultivar. Or, perhaps consult with a local garden nursery about alternatives that might do well in your climate in late summer. Good luck - and best wishes for a beautiful wedding!
