Penny Mac Hydrangea

This is a popular deciduous shrub with large rounded clusters of either deep blue or pink flowers that bloom repeatedly throughout the warm months on old and new growth. Flower color is dependent on soil acidity.  Add aluminum sulfate to the soil to make the flowers more blue or add lime to the soil to make the flowers more pink.  This variety is also ideal for cut flower arrangements.  Lush, dark green leaves hold their color through the season. Performs best in Zones 5-10 in rich, moist soil and needs regular watering especially during times of extreme heat.
