Penny Mac Hydrangea is recommended for mass planting, hedges/screening, general garden use, and container planting.
Propagation and Care
The Penny Mac hydrangea is a hardy plant that provides flowers throughout the summer season, blooming on both old and new wood. It's a great choice for gardeners who want a low-maintenance plant.

Here are some key care tips to keep in mind:
- Water regularly, especially during dry weather.

Care
To keep your Penny Mac hydrangea thriving, you'll want to plant it in a spot where it gets part sun, part shade. This will help it receive the right amount of light for optimal growth.

Using a rich garden soil mix with plenty of loam is essential for your hydrangea's health. This type of soil will provide the necessary nutrients for blooming flowers.
Watering your hydrangea regularly, especially during dry weather, is crucial. This will prevent the plant from becoming stressed and promote healthy growth.
Fertilizing your hydrangea in the spring will give it a boost of energy to produce beautiful flowers throughout the summer season.
Overwintering
Overwintering is a crucial step in ensuring your Penny Mac Hydrangea survives the cold winter months. Hardiness is not a guarantee, as macrophylla hydrangeas can still be damaged by prolonged cold snaps or ice storms.
In USDA zone 5, it's not uncommon for these plants to fail to form buds. Adding a layer of lightweight mulch, such as pine straw, can help protect the roots from extreme cold.
Giving your Penny Mac hydrangea some extra water during a very dry winter can also make a big difference. This will help the plant stay healthy and resilient throughout the winter.
Wrapping your shrub loosely in burlap can shield it from wind exposure and ice formation on its branches. This simple step can go a long way in safeguarding your hydrangea's health.

Propagating

Propagating your Penny Mac Hydrangea is a great way to share its beauty with friends and family. The best time to propagate is in the spring, when the plant is actively growing.
To propagate by division, your plant should be at least 3 years old and have at least two good-sized canes growing from the roots. This will give the new plant a good chance to establish itself.
To divide your plant, dig it up carefully and look for a natural junction point in the root ball. Cut a well-rooted section at this point, and plant it as you would a new hydrangea shrub.
Dividing your plant can be a bit tricky, but it's worth the effort to get a healthy new plant. Water your new division regularly, but be careful not to overwater.
If you prefer to propagate by cutting, you can take a section with at least one node from a new growth shoot. Dip the cut edge in rooting hormone powder to help it take root.

Here's a step-by-step guide to propagating by cutting:
- Cut a section with at least one node from a new growth shoot.
- Dip the cut edge in rooting hormone powder.
- Place the cutting in a container with moistened potting mix.
- It should form roots within a month.
- Once it has formed roots, transplant it to a large pot or into the garden.
vs Endless Summer
The Penny Mac Hydrangea is a great choice for those who want a low-maintenance shrub that still packs a punch in terms of blooms.
It's a big difference from the Endless Summer Hydrangea, which requires more frequent pruning to maintain its shape and promote blooming.
The Penny Mac Hydrangea is hardy in zones 3-8, making it a great option for gardeners in colder climates.
It produces large, round clusters of blue flowers that can grow up to 12 inches across.
