Bigleaf Hydrangea 'Masja Red': Intense Red Mophead for Bold Color

Bigleaf Hydrangea 'Masja Red': Saturated Red in a Compact Package

Hydrangea macrophylla 'Masja Red' is a selection bred for one purpose: to deliver the most intense, true red mophead flowers possible in neutral to alkaline soils. It succeeds admirably, producing blooms of startling vermillion richness on a plant compact enough for modern gardens.

Vermillion Velour

The mophead inflorescences are large, 7–9 inches across, composed of broad, velvety sterile florets in a deep, saturated red—carmine to vermillion—in neutral to slightly alkaline soils. In acidic conditions, the color shifts to a rich purple-red. The florets are heavily textured, almost leathery, giving the flower heads substantial presence and longevity. Color holds exceptionally well without fading.

The plant is notably compact, 2–3 feet tall and wide, with strong stems that hold the heavy heads upright. Foliage is dark green and glossy.

Culture for Maximum Red

To maintain true red, avoid acidifying amendments. Apply lime if soil is naturally acidic. Morning sun or bright shade, consistent moisture, rich well-drained soil. Hardy in USDA zones 6–9. Blooms on old wood. Winter protection in zone 6. The compact habit makes it suitable for containers.
