Panicle hydrangeas, also known as Hydrangea paniculata, do enjoy full sun. However, it is important to note that they can tolerate some shade as well. In fact, they can thrive in a variety of light conditions, but their growth and overall appearance may vary depending on the amount of sun they receive.
Ideally, panicle hydrangeas should be planted in a location that receives at least four hours of direct sunlight each day. This will ensure that they develop strong stems and a compact, bushy growth habit. When exposed to sufficient sunlight, the plants are more likely to produce an abundance of large, showy flower panicles.
If the area you have in mind for planting panicle hydrangeas is shaded, it is still possible to grow them successfully. However, it’s important to provide them with filtered light throughout the day to prevent them from stretching and becoming weak and spindly. This can be achieved by planting them under the canopy of taller trees or in areas that receive dappled sunlight.
In my personal experience, I have grown panicle hydrangeas in both full sun and partial shade. Those planted in full sun locations have always exhibited more robust growth and larger flower clusters compared to those in shaded areas. The ones in full sun also had sturdier stems and were more resistant to wind damage.
To summarize, while panicle hydrangeas can tolerate some shade, they truly thrive when given at least four hours of direct sunlight each day. This ensures strong stems, compact growth, and abundant blooms. If planting in shaded conditions, it is important to provide them with filtered light throughout the day to prevent weak and spindly growth.
