The Seemannii hydrangea, with its delicate pale green bracts and elegant white florets, is a stunning addition to any garden or landscape. This particular variety of hydrangea is slightly tender, meaning it may require some extra care in colder climates.
When determining the hardiness zone for a plant, it is important to consider the lowest average winter temperature in that region. The Seemannii hydrangea is considered hardy to zone 7. This means that it can tolerate winter temperatures down to around 0 to 10 degrees Fahrenheit (-18 to -12 degrees Celsius).
If you live in a colder climate with temperatures below this range, it is recommended to provide some extra protection for the plant during the winter months. This could include covering it with a layer of mulch or burlap, or even bringing it indoors if possible.
It is also worth noting that the Seemannii hydrangea is a climbing variety, so it benefits from being trained to grow on a sheltered wall or trellis. This not only provides support for the plant but also helps to protect it from harsh weather conditions.
In my personal experience, I have seen the Seemannii hydrangea thrive in zone 7 gardens. The delicate green bracts create a beautiful contrast against the white florets, and the plant can reach an impressive height of 30 feet, making it a stunning focal point in any landscape.
If you are considering adding the Seemannii hydrangea to your garden, be sure to check your hardiness zone to ensure it will be able to withstand your winter temperatures. With proper care and protection, this hydrangea can provide years of beauty and enjoyment in your outdoor space.
