About
Acer palmatum 'Anne Irene' PBR (P) is a compact, upright tree that reaches a height and width of approximately 3 meters over time. Its foliage features five lobes with serrated edges, initially emerging in a lime green hue, transitioning to yellow-green during the summer, and displaying red-tinged margins. In the fall, the leaves turn yellow-orange. While the red flowers in spring are subtle, they are succeeded by winged fruits that exhibit both red and green colors in autumn.
About the genus
Acer consists of deciduous trees or sizable shrubs featuring pairs of leaves that are frequently palmately lobed. These plants produce small flowers that give way to distinctive winged fruits. Numerous species display vibrant autumn foliage, while certain varieties also exhibit decorative stems.

Care notes
