White spirea, also known as Spiraea betulifolia, is a deciduous shrub that can reach a moderate height. On average, white spirea can grow to be around 3 to 5 feet tall and wide. However, it’s important to note that the exact height can vary depending on various factors such as growing conditions, pruning, and overall care.
In my personal experience, I have seen white spirea plants that have reached heights of up to 6 feet in optimal growing conditions. These conditions include providing the plant with sufficient sunlight, regular watering, and proper pruning.
When it comes to sunlight requirements, white spirea performs best in full sun. This means it should be planted in an area that receives at least 6 to 8 hours of direct sunlight per day. When grown in full sun, white spirea tends to produce more blooms, resulting in a more vibrant and colorful display. The foliage also tends to have a brighter and more intense fall coloration when the plant receives ample sunlight.
While white spirea can tolerate light shade, it’s important to note that spring bloomers are generally more shade tolerant than summer bloomers. Spring-blooming varieties, such as Spiraea betulifolia ‘Tor’, can handle a bit more shade and still perform well. However, for optimal growth and blooming, it is best to provide as much sunlight as possible.
To maintain the desired height and shape of white spirea, regular pruning is recommended. Pruning can be done in early spring or after flowering. By selectively removing older or dead wood and shaping the plant, you can help maintain its size and overall appearance.
White spirea typically grows to be around 3 to 5 feet tall and wide, but can reach heights of up to 6 feet under ideal conditions. Providing full sun is crucial for the best bloom production, vibrant color, and bright fall foliage. While white spirea can tolerate light shade, it’s important to prioritize sunlight for optimal growth and flowering. Regular pruning can also help maintain the desired height and shape of the plant.
