I have flower bed area in front of my home that's probably 70 to 75 feet in length that I plant with Seasonal flowers. Around January 1 I had planted over 150 Pansies - almost 50% have now died and I need to plant something that is hearty in 80 to 100 degree heat plus direct sunlight until I replant in the Fall with the pansies. The former owner had impatiens in the same areas. Any thoughts? I really only want to do this twice a year. So I already know the Pansies work out for over half the year.

Thanks!
