When it comes to comparing viburnums and hydrangeas, there are several noticeable differences between these two types of shrubs. Firstly, one of the most significant distinctions is the bloom period. Hydrangeas have a much longer bloom period compared to viburnums. The blossoms of hydrangeas can remain on the shrub for as long as two months, providing a longer-lasting display of flowers. On the other hand, viburnums typically have a shorter bloom period, usually occurring during the summer months.
Another difference between these two shrubs is the timing of their bloom. Hydrangeas primarily bloom in the spring, showcasing their beautiful flowers during this season. However, some hydrangea varieties have the ability to rebloom in the fall, offering a second round of blossoms later in the year. This can be a delightful surprise for gardeners who enjoy extended periods of flowering.
In terms of flower size, hydrangeas generally have smaller flower heads compared to viburnums. The flower heads of hydrangeas typically do not exceed 8 inches (20.5 cm) in diameter. This more compact size can be appealing for those who prefer a more delicate and intricate look in their garden. On the other hand, viburnums often have larger flower clusters, which can create a bold and showy display in the landscape.
It’s also important to note that both hydrangeas and viburnums offer a variety of flower colors. While hydrangeas are well-known for their ability to change color based on the soil pH, viburnums come in a range of hues as well, including shades of white, pink, and red. This diversity in color options allows gardeners to choose the best fit for their desired aesthetic.
In terms of care, hydrangeas and viburnums have slightly different requirements. Hydrangeas often prefer moist soil and benefit from regular watering to maintain their health and vibrant blooms. They also appreciate some shade during the hottest parts of the day. Viburnums, on the other hand, are generally more tolerant of different soil conditions and can handle a bit more sun exposure. However, it’s important to ensure they receive adequate water during dry periods, especially when they are establishing their root systems.
While both viburnums and hydrangeas offer beautiful flowers, there are notable differences between these two types of shrubs. Hydrangeas have a longer bloom period, with the potential for reblooming in the fall. They have smaller flower heads and require a bit more care in terms of watering and shade. Viburnums, on the other hand, bloom during the summer and have larger flower clusters. They are generally more adaptable to different soil conditions and can tolerate more sun exposure. Ultimately, the choice between these two shrubs depends on personal preference, desired bloom period, and the specific growing conditions in your garden.
