Unfortunately, this scene from Nitobe Memorial Garden was photographed two weeks ago, so anyone wanting to see the Garden with these colours will now have to wait another year. The red-leaved maple in the foreground is most likely Acer palmatum ‘Osakazuki’, and I believe it is slated to be moved this winter to another area of the Garden.
Nitobe Memorial Garden was originally planted over fifty years ago, and has been described as one of the most authentic Japanese gardens outside of Japan. Over the next few years, some difficult decisions will be made to renew some of the plantings (e.g., decades-old cherry trees that are declining in health). The challenges will be to do so while honouring the spirit & intent of the original garden design, ensuring the present-day garden is not visually harmed, and, planting (and planning) for the future.
