My little sister got a Blanket Flower and wants it to last longer than her petunias did, which lasted 2 months. We wanted to know what sort of special attention it needs or if it's just a more laid-back type of flower. Also, there were little red ants in her petunia flower pot when we took out the soil. We were wondering if the ants might have caused the petunias to die so quickly. Or maybe it was just the hot Texas sun.
