Big bi-color blooms on a classic French Bigleaf, the Firefly Bigleaf Hydrangea (Hydrangea macrophylla ‘HORCOS’) is a unique, semi-double mophead! Reblooming rounded clusters of cream and red blossoms almost don’t look real! The vivid color of the blooms looks to have an artist’s touch all summer until fall, when they become dried pompoms for indoor décor or winter interest.
Backed by a dense clump of very broad deep green leaves that have the classic Hydrangea quilting and toothy edges for an elegant, soft effect in the landscape. The big round clusters are tightly packed and look incredible in the garden, in a vase bouquet or as specimen plants in large planters! Plus, they return for a second flush of blooms later in the growing season.
Firefly is hardy in zones 6 and up, these are fairly heat-tolerant! Planting your Firefly in acidic soils will change the red/cream combination to more of a red/pink hue.
Mophead Hydrangeas are fantastic back of the border backdrops and accents. So use long rows of them for privacy and screening and elegant property division. Great facer shrubs for larger, leggier plants and trees to hide their bare stems, and these tough plants add a graceful element to your home’s foundation planting and friendly fences separating your front yard from the sidewalk.
Firefly Bigleaf Hydrangea looks amazing in Cottage and cutting borders, behind Perennial and cutting gardens, and are of course ideal in the pollinator garden! Indoors or out, let these vivid blooms create colorful hedges and focal points! You’ll love the bouquets and dried décor you will make!
The best time to prune Bigleaf Hydrangea is as they break dormancy. Prefers afternoon shade in hot climates, but morning sun to dry the leaves of dew. Plant in an enriched, well-drained and consistently moist soil environment.
The Firefly Bigleaf Hydrangea is just what you need to add some serious color to your landscape this year!
