Hydrangea involucrata 'Blue Bunny' is a charming cultivar of the involucrata species, distinguished by its unique bud formation: pairs of large, fuzzy, rabbit-ear-like bracts that enclose the developing flower heads. These persistent bracts remain attractive long after the flowers open, giving the plant a whimsical, animal-like quality.
In late spring, the terminal buds swell into pairs of large, ovate, densely fuzzy bracts—soft gray-green and irresistibly tactile. They truly resemble rabbit ears. As the lacecap flowers emerge, the bracts persist, framing the inflorescence. The lacecaps themselves are delicate: a central dome of tiny blue fertile flowers (in acid soil) with a sparse ring of white sterile florets.
The plant forms an open, arching shrub 3–4 feet tall and wide, with velvety, broadly ovate leaves. The species H. involucrata is native to Japan and Taiwan, preferring woodland conditions.
Bright shade or dappled sun, consistently moist, humus-rich soil. Hardy in USDA zones 6–8. The fuzzy bracts are a distinctive ornamental feature lasting months. Blooms on old wood. Protect from drying winds.
'Blue Bunny' delights children and adults alike—the rabbit ears invite touch and imagination. Ideal for woodland gardens, sensory gardens, and shaded borders where its unique bud stage provides months of interest. A cultivar that combines botanical curiosity with genuine charm.
