The best characteristics of PETunias and calibraCHOAS are combined in one plant. Hence, we have PETCHOAS. They deliver exceptional garden performance in baskets, pots and the flower border, standing up to rain, wind, heat, humidity and even light frost. Non-sticky foliage keeps plants looking clean and strong root systems minimize disease and pH problems. They develop into semi-mounding plants 12 inches high and 15 inches wide, forming giant balls coated with large blooms that last all summer.
