Where to Plant a Penny Mac Hydrangea

'Penny Mac' goes pink in neutral soils.

Mophead hydrangeas produce large spherical flower clusters, and the 'Penny Mac' is a mophead with the ability to bloom more than once in a growing season. Get your hydrangea off to a healthy start with the right planting environment.

Soil pH

Since 'Penny Mac' is a mophead hydrangea, it can turn color based on the soil pH of the planting site. Putting a 'Penny Mac' in acidic soil will get you blue hydrangea flowers, while planting the shrub in neutral or alkaline soil will produce pink flowers.

Planting Zone

Like all hydrangeas, the 'Penny Mac' does best in well-draining, rich soil. It may develop root rot if planted in poorly draining soil. The plants aren't drought tolerant, so plan to water hydrangeas with 1 inch of water weekly. These plants do best in partial shade, but can also grow in full sun.

Geography

'Penny Mac' and other mophead hydrangeas can be planted in USDA plant hardiness zones 2 to 8.
