hortensia · Hydrangea macrophylla
Also known as: mophead hydrangea
Bigleaf hydrangea thrives in consistently moist, well-drained soil and partial shade. Special care points include the need for protection from afternoon sun to prevent scorching and regular watering to keep the soil moist but not waterlogged. Soil pH affects flower color; for preservation of blue blooms, maintain an acidic soil pH.
