This Royal Blue Hydrangea Mix brings a beautiful display of lush foliage and rounded flower heads to shady and semi-shaded Cape Town gardens. Typically flowers from late Spring through Summer. This classic Hydrangea produces impressive mophead-style flowers in rich blue shades when grown in suitable acidic soil. Flower colour can naturally vary towards lilac, purple or pink depending on the soil conditions. This deciduous flowering shrub is a lovely way to bring a soft, romantic feel to the garden, while its long-lasting flower heads are also excellent for fresh arrangements and can be dried for decorative displays.
Plant in fertile, moisture-retentive soil that drains well, choosing morning sun or semi-shade rather than a hot, exposed position. Water newly planted Hydrangeas regularly while they're establishing and during Cape Towns dry summer days. A layer of organic mulch can help maintain more even soil moisture , while winter watering should be reduced when natural rainfall is sufficient. In mid-spring remove faded flower heads and lightly trim back to healthy buds.
The colour of the Hydrangea can be influenced by the soil it grows in. Blue flowers are favoured by acidic conditions where aluminium is available, while plants growing in less acidic or alkaline conditions can have a surprising effect on the colour of your hydrangea's seasonal display.
