'Penny Mac' Hydrangea

Penny Mac Hydrangea

Flower:  Large clusters of either blue or pink flowers throughout the summer. 'Penny Mac' blooms on last years wood and again on the current years growth.  Flower color is soil dependent.  Acid soils, where aluminum is present will give you blue flowers. Alkaline soils tend to give pink flowers.  Entire websites are devoted to changing flower colors on Hydrangeas.

Size:  Fast grower to 5 feet tall and 5 feet wide.  'Penny Mac' has a dense mounding growth habit.  Pruning after the first flowering

Foliage:  Very nice large dark green foliage.  Foliage holds up better in afternoon shade or filtered sunlight.

Hardiness Zones:  6-9.  Probably zone 5 with protection

Light Requirement:  Morning sun and afternoon shade is best, but some afternoon sun with additional irrigation will work.

Drought Tolerance:  Moderate.  Some additional water in the summer is necessary.  Afternoon wilting in extreme heat is normal and is not always a sign of dry soil.  Wait until evening to determine if watering is necessary.

Notes:  'Penny Mac' is a vigorous grower returning quickly from dormancy every season.  Originally introduced by Penny McHenry who was the founder of the Hydrangea Society. Very nice foliage and tight growth habit.  Very low maintenance plant if properly place
