Martha's Vineyard Bigleaf Hydrangea

Seaside Serenade Martha's Vineyard Bigleaf Hydrangea (Hydrangea macrophylla 'HORTMAVI')

Seaside Serenade Martha's Vineyard is a compact, strong-stemmed mophead hydrangea prized for hard, dark red flower heads that rebloom from early summer into fall. Dense foliage and sturdy stems hold 10 inch or larger blooms upright, with leaves taking on dark bronze tones in autumn.

Distinctive Features

Rich, long-lasting dark red mopheads on thick, non-flopping stems provide extended color, while a naturally tidy habit suits small gardens and containers. Reliable rebloom keeps fresh flowers coming through the season.

Growing Conditions

• Sun Exposure: Morning sun with afternoon shade; avoid hot, reflected exposures.
• Soil: Moist, well drained, humus-rich soil; maintain even moisture for best rebloom.
• Water: Keep evenly moist, especially during bud and bloom; do not allow prolonged dryness.
• USDA Hardiness Zones: 5 to 9.
• Mature Size: Typically 3 to 4 ft tall and 3 to 4 ft wide.

Ideal Uses

• Foundation Planting: Compact habit fits under windows and along paths.
• Mixed Borders: Pairs with hostas, ferns, and summer perennials.
• Containers: Performs in large pots with consistent moisture and shade.

Low Maintenance Care

• Watering: Water deeply and regularly in summer; mulch to keep roots cool and moist.
• Pruning: Minimal; remove spent heads and lightly shape after main bloom, preserving new shoots for rebloom.
• Fertilizing: Feed in spring with a balanced fertilizer; avoid excess nitrogen that reduces flowering.
• Mulching: Maintain a 2 inch organic mulch, keeping it off the stems.
• Notes: Protect swelling buds from late frosts; provide afternoon shade to preserve flower quality.
