When many flowering shrubs begin to fade in late summer, panicle hydrangeas are just hitting their stride. Reliable bloomers, easy to grow and packed with flowers that last for months, they have quickly become one of the most popular landscape shrubs for homeowners throughout Maine.
Two standout varieties are Bobo® and Little Lime®. Both produce an abundance of creamy white blooms that gradually take on soft pink and burgundy tones as autumn approaches, extending the season of interest well beyond summer.
Bobo® Hydrangea
Don't let its compact size fool you. Bobo is one of the heaviest blooming hydrangeas available, covering itself with large flower clusters from top to bottom every summer.
Growing just 2 to 3 feet tall and wide, Bobo is perfect for:
- Foundation plantings
- Front borders
- Small gardens
- Containers
Its naturally tidy habit means very little pruning is required, and the abundant blooms create an impressive display from midsummer into fall.
Little Lime® Hydrangea
Little Lime offers the same dependable performance as the popular Limelight hydrangea in a more manageable size. Growing about 3 to 5 feet tall, it fits comfortably into most home landscapes while producing large cone-shaped flower heads throughout the season.
The blooms emerge a fresh lime green, mature to creamy white and gradually develop rosy pink highlights as cooler nights arrive, providing months of changing color.
Little Lime works beautifully as:
- A specimen shrub
- A flowering hedge
- A mixed shrub border
- An anchor plant in foundation landscapes
Why They Bloom So Reliably
Unlike some hydrangeas that bloom on old wood and can lose flower buds after a harsh winter, panicle hydrangeas bloom on new growth. That means they develop their flower buds each spring, providing dependable blooms year after year, even after cold Maine winters.
They also tolerate full sun better than many other hydrangea varieties, making them an excellent choice for bright landscapes where consistent color is desired throughout the growing season.
Keeping the Show Going
Panicle hydrangeas are remarkably easy to care for.
- Water deeply during extended dry periods, especially during their first growing season.
- Apply a layer of mulch to help retain soil moisture and regulate soil temperature.
- Fertilize lightly in spring with a balanced slow-release fertilizer.
- Prune in late winter or early spring before new growth begins to encourage vigorous stems and abundant blooms.
Even after the flowers begin to dry, many gardeners leave them in place through winter, where they continue adding texture and interest to the landscape.
Late Summer Is the Perfect Time to Plant
With warm soil and cooler nights arriving soon, late summer is an excellent time to plant panicle hydrangeas. The favorable growing conditions encourage strong root development before winter arrives, helping plants establish quickly for an even more impressive display next year.
Whether you choose the compact beauty of Bobo or the versatile size of Little Lime, panicle hydrangeas deliver reliable blooms, outstanding fall color and years of easy-care performance.
