When it comes to choosing the best hydrangeas for the Maine region, it is important to consider varieties that are well-suited to the local climate and growing conditions. One key factor to keep in mind is the ability of the hydrangea to bloom on new wood, meaning that the flowering buds are not at risk of being damaged by late frosts.
Two hydrangea varieties that fit this criteria and are excellent choices for Maine gardens are the Panicle hydrangea (Hydrangea paniculata) and the smooth hydrangea (Hydrangea arborescens).
Panicle hydrangeas, also known as peegee hydrangeas, are hardy and adaptable plants that can thrive in a wide range of conditions. They are characterized by their large, cone-shaped flower heads that start off white and gradually turn pink as they mature. One popular cultivar is ‘Limelight’, which features lime green flowers that age to a soft pink. Another option is ‘Pinky Winky’, which has white flowers that fade to pink and is known for its strong stems that prevent the flowers from flopping over.
Smooth hydrangeas, such as the popular ‘Annabelle’ cultivar, are native to the eastern United States and are well-suited to the New England region. These hydrangeas produce large, round flower heads that start off green and gradually turn white as they mature. ‘Annabelle’ is known for its abundant flowers and sturdy stems, making it a favorite among gardeners. Another smooth hydrangea to consider is ‘Incrediball’, which boasts even larger flower heads than ‘Annabelle’.
Both Panicle hydrangeas and smooth hydrangeas are relatively low-maintenance and easy to grow. They prefer well-drained soil and can tolerate a range of light conditions, from full sun to partial shade. These hydrangeas also have the advantage of being able to withstand colder temperatures, making them ideal for the Maine climate.
In addition to their ability to bloom on new wood, another benefit of these hydrangeas is that they can be pruned in late winter or early spring to control their size and shape. This flexibility allows gardeners to maintain the desired appearance of their hydrangeas without sacrificing the potential for abundant blooms.
When selecting hydrangeas for a Maine garden, it is wise to choose varieties that are hardy, adaptable, and able to bloom on new wood. Panicle hydrangeas and smooth hydrangeas fit these criteria and offer a range of beautiful cultivars to choose from. By considering these factors, gardeners can enjoy the beauty of hydrangeas in their Maine landscapes while minimizing the risk of frost damage to their flowering buds.
