Hydrangeas are one of the most beloved flowering shrubs in many gardens, admired for their stunning blooms and versatility. Among the various types of hydrangeas, Endless Summer hydrangeas have gained popularity for their ability to bloom repeatedly throughout the growing season. One of the most intriguing aspects of these plants is their unique growth habit and blooming characteristics. In this article, we will delve into the specifics of whether Endless Summer hydrangeas bloom on new wood, exploring the implications of this trait for gardeners and hydrangea enthusiasts.
Understanding Hydrangea Basics
Before diving into the specifics of Endless Summer hydrangeas, it’s essential to understand some basic concepts related to hydrangea growth and blooming. Hydrangeas are deciduous shrubs that produce beautiful flowers in various colors, including pink, blue, and white. The color of the flowers can be influenced by the pH of the soil, with more acidic soils producing blue flowers and more alkaline soils resulting in pink flowers.
Growth Habit and Wood Types
Hydrangeas, like other shrubs, have a growth habit that includes the development of old and new wood. Old wood refers to the stems that have been on the plant since the previous growing season, while new wood is the growth that occurs during the current season. The distinction between old and new wood is crucial because it affects when and how hydrangeas bloom. Traditional bigleaf hydrangeas (Hydrangea macrophylla) bloom on old wood, meaning they produce flowers on stems that grew the previous year. This characteristic makes them sensitive to late frosts and pruning practices, as damaging the old wood can reduce or eliminate flowering.
Impact of Old Wood Dependency
The dependency on old wood for blooming can pose challenges for gardeners, especially in regions with harsh winters or late spring frosts. If the old wood is damaged or killed, the plant may not produce flowers the following season. This vulnerability led to the development of hydrangea varieties that can bloom on new wood, offering more flexibility and reliability in flowering.
Endless Summer Hydrangeas: A Breakthrough in Blooming
Endless Summer hydrangeas are a cultivar of bigleaf hydrangea (Hydrangea macrophylla ‘Bailmer’) that has been bred to bloom on both old and new wood. This unique characteristic allows them to produce flowers throughout the growing season, from spring to fall, under the right conditions. The ability to bloom on new wood means that even if the old wood is damaged, the plant can still produce flowers on the new growth that occurs during the current season.
