The Maple Society Open Science Initiative (OSI) is pleased to present Peter Gregory's Acer sieboldianum Miquel (1865) profile, with photographs by Hugh Angus. Siebold's Maple is known for both for its stunning red and orange autumn colors and ease of cultivation. We hope you enjoy the fascinating account of this beautiful Japanese Maple's introduction, during a time when Imperial Japan was still largely closed to outsiders. Check it out at Open Science at the Maple Society | The Maple Society This is the next in our OSI series featuring Peter's maple profiles. Coming soon: Father David's Maple, Acer davidii.
