According to Express, Prince Charles revealed during a recent interview that his grandson, Prince George, likes to measure his height against a tree on Charles' estate, which is located in the picturesque Cotswolds area. It was planted by the Prince of Wales and is now the ideal height for his grandchildren to keep track of their rapid growth in real time. As Charles explained, "The fun is to get grandchildren to plant a tree now and then see so they can measure themselves, if you know what I mean, by the size of the tree." George planted a balsam tree at the stunning Highgrove estate back in 2015, when he was just 2, and according to Charles, "This thing has shot up."

In fact, it's now towering above the barn, which for George is pretty impressive considering it constitutes a growth of around 3 feet in one year. The Prince of Wales' estate is located in Gloucestershire and was built in the late 18th century. Its official site describes how the property "unfolds in a succession of personal and inspiring tableaux, each reflecting The Prince's interests and enthusiasms." Royal experts opined that George could one day inherit the estate himself, thereby enabling him to plant trees with his own grandchildren and track their height, too.
