The most sun-tolerant of all hydrangea types with the longest bloom season, Panicle Hydrangeas are low-maintenance, easy,, and big time showy bloomers making them reliable & versatile in the landscape. Flowers emerge creamy white to lime green, then age to blush pink through the season — some even deepen to a deep pink in fall. New varieties are being developed every year! You can purchase Panicle Hydrangeas in a typical shrub form or a tree form.
- Bloom Colors: Creamy white to lime green to blush pink or even deep pink
- Bloom Time: Summer to Fall
- Sun Needs: Part Sun to Full Sun but at least 4+ hours a day
- Best For: Versatile in the landscape from small varieties growing just up to 2′ to larger varieties growing even up to 12′ tall!
Care Tips
- Light: 4+ hours of sun a day. If planting in full sun, you may need to increase water needs during the summer
- Water: Once planted, water deeply & thoroughly the first season until well-established. Moist soil is great but wet soil will cause root rot.
- Tips: Mulch around the base of the plant to help keep weeds down & moisture in (but do not pile mulch around the trunk). Water around the roots to avoid wetting the blooms and causing premature bloom fade.
Fertilizing
Hydrangeas need a good source of nutrition to produce dense blooms. Fertilize Hydrangeas twice per year, once in early spring (March-April) when new foliage begins to sprout and once again mid-summer (July-August). You can use a variety of granular fertilizers on Panicle Hydrangeas such a Fertilome’s Gardener’s Special or Espoma’s Plant Tone.
Pruning
Pruning is more simple than with Macrophylla varieties of Hydrangeas since Panicle Hydrangeas bloom on new wood. Still proper pruning and maintenance will reward you with better branching & more blooms.
Early Spring | For both panicle trees and shrubs, prune branches down to and shape in late winter (Jan- early March). You can remove any dead or damaged branches.
Summer | Cut for flower arrangements & deadhead spent blooms to keep a neat appearance & encourage more blooms.
Fall | Only remove dead or damaged areas at this time.
Optional: Leave dried blooms on the plant to provide winter interest
