Shade hydrangeas prefer moist soil and regular watering during the growing season. For most, in order to obtain the blue flower color, apply 2 tablespoons of aluminum sulfate near the base of the plant. A rusty nail or coffee grounds will also increase the acidity of the soil which makes the flowers turn blue.
Cherry-Go-Round™ Reblooming Hydrangea
Hydrangea macrophylla 'Hokomaburlac' USPPAF
For years plant breeders have been working frantically to develop a truly red flowering mophead hydrangea. Blooming Easy up in Vancouver British Columbia has finally done it! Last summer plant industry trade show attendees were so excited to finally fine a true solid red flowering hydrangea for shade. I think I speak for many growers when I say that we are so happy to be able to grow this one and bring it to market in 2024!
