Hydrangeas are always associated with summer and yet they usually start flowering during the latter part of spring and continue until Christmas. They are reputed to be amongst the most beautiful and desirable flowering shrubs around the globe. A bold statement indeed but they invariably uphold it with great dignity. They grow in light or dappled shade and enjoy well drained loamy soil and cool roots.
The colour of hydrangea flowers is influenced by the chemical composition of the soil. Simply put, acid soils with available aluminium produce blue flowers whilst alakaline or aluminium free soils promote pink flowers. White hydrangea blooms are not affected to any significant level by the soil structure.
