Acer × freemanii ‘Sienna Glen’, or Freeman Maple 'Sienna Glen', is a fast-growing ornamental tree, recognized for its naturally narrow pyramidal habit, perfect for confined spaces or urban street planting. Its deeply cut dark green foliage offers dense shade during the summer, then turns vibrant orange-red in the fall, creating a vivid seasonal display. This cultivar is particularly valued for its resistance to drought, wind, and urban conditions, while also being very hardy, making it an excellent choice for Quebec landscapes. It thrives in well-drained soil with sunny exposure. Thanks to its structured form, minimal maintenance, and striking autumnal coloration, the 'Sienna Glen' maple is a wise choice for effectively beautifying avenues, courtyards, and large residential properties.
