Pink hydrangea flowers
Hydrangeas are deciduous shrubs that produce pink or blue flowers. Also known as bigleaf or French hydrangeas, these shrubs are hardy up to U.S. Department of Agriculture Plant Hardiness Zone 6, which includes much of southern Ontario, Canada. Does this Spark an idea?
Colors
The color of a hydrangea will depend on the soil where it's grown. If your soil is acidic, the plant will produce blue flowers, while alkaline soil results in pink blooms. The presence of aluminum in the soil is what determines the coloration, according to the Clemson University Cooperative Extension.
Light
Plant your hydrangeas in a place that gets sun in the morning but shade in the afternoon. Planting in hot, dry locations will result in stunted growth and no flowers.
Moisture
Hydrangeas should be planted in well-drained, organic soil. Keep the soil around your hydrangea moist at all times, but do not over-water. Soggy or waterlogged soil can promote root rot or other diseases.
