More than 1,000 hydrangeas, in 150 varieties, are interspersed with the rhododendrons.
They are planted on a forested north-facing slope of mature deciduous trees, with gentle sloping walkways gracing the hillside.
Their blossoms appear in May and continue until October.
Colors include blue, pink, white, lavender and purple depending on the variety and soil acidity.
The Hydrangea Gardens, with 5 months of blooms, tapers from the house to the start of the Pleasance Garden near the valley.
Wooden benches provide rest along the path.
Views are stunning from above and below.
