Which garden is known for its extensive variety and features, designed with the unique input of Gertrude Jekyll?

Wisley Gardens is notable for its extensive variety and features, as it serves as the flagship garden of the Royal Horticultural Society (RHS). Gertrude Jekyll, a prominent influence in garden design, contributed significantly to the development of various garden designs, focusing on color, plant combinations, and the seasonal interest of the landscape. This characteristic is reflected in the thoughtful arrangements and diverse plantings found at Wisley, making it a prime example of her vision.

While other gardens, such as those at Hampton Court, Leeds Castle, and Scotney Castle, possess historical significance and beautiful designs, they do not have the same direct association with Gertrude Jekyll's contributions. Her work at Wisley Gardens is particularly celebrated for showcasing various horticultural practices and landscaping techniques that align with her philosophy of creating gardens that harmonize with nature throughout the seasons. Thus, Wisley Gardens stands out as the correct answer, as it embodies the spirit of Jekyll's legacy in garden design.
