In which century did knot gardens become popular in England?

Knot gardens became particularly popular in England during the 16th century, reflecting the elaborate and intricate garden designs of the Tudor period. This era saw a rise in Renaissance influences, leading to more formalized garden layouts, including geometric patterns and the use of box hedging to create the distinctive 'knot' appearance. Knot gardens were often designed for both aesthetic appeal and as symbols of status and sophistication, showcasing the gardening skills of the time. This unique style of gardening was characterized by its complex patterns, often incorporating a mix of flowers and herbs for both beauty and utility.

In contrast, earlier centuries did not have the same emphasis on such formal garden structures, while later centuries shifted towards different styles and movements, such as the picturesque gardens of the 18th century and the more naturalistic designs of the 20th century.
