Hydrangeas are celebrated for their stunning blooms, which can be found in a range of colours that often depend on the pH level of the soil in which they are planted. This florist guide explores the various colours of hydrangeas and their origins.
Blue Hydrangeas
Origins: Blue hydrangeas are primarily linked to the Hydrangea macrophylla species, commonly known as mophead hydrangeas. Their blue hue is influenced by acidic soil conditions, which allow the availability of aluminium ions.
Soil pH: A soil pH of 5.5 or lower promotes the blue coloration.
Cultivation Tips: To achieve blue blooms, amend the soil with substances such as sulfur or organic matter to lower the pH.
Pink Hydrangeas
Origins: Pink hydrangeas also belong to the Hydrangea macrophylla family. When the soil's pH is neutral to slightly alkaline, pink pigments, known as anthocyanins, dominate.
Soil pH: A soil pH of 6.0 to 6.5 tends to yield pink blooms.
Cultivation Tips: Adding lime to the soil can shift the pH towards more alkaline levels, promoting pink flowers.
Purple Hydrangeas
Origins: Purple blooms often result from a mix of the conditions favourable for both blue and pink hydrangeas. The Hydrangea macrophylla variety exhibits these unique shades when growing in neutral soils.
Soil pH: A soil pH around 6.0 will lead to hues that can display a beautiful gradient of pink to blue.
Cultivation Tips: Cultivating in soil with a pH around neutral allows for the emergence of these captivating colours.
White Hydrangeas
Origins: White hydrangeas, notably from species such as Hydrangea paniculata and Hydrangea arborescens, remain unaffected by the soil's pH. Instead, their colour stems from their genetic makeup.
Soil pH: White blooms are consistent regardless of soil conditions.
Cultivation Tips: Regular watering and well-draining soil can enhance the health and longevity of white hydrangeas.
Green Hydrangeas
Origins: Green hydrangeas, such as Hydrangea quercifolia, are distinct for their early summer blooms that fade to green as they mature.
Soil pH: The colour is not entirely influenced by soil pH but rather by the specific varieties.
Cultivation Tips: Ensure adequate light and moisture for vibrant green foliage and blooms.
