About
Acer japonicum 'Green Cascade' is a deciduous large shrub or small tree characterized by its graceful, weeping form. The foliage consists of deeply lobed leaves, typically 9 to 11 lobes, which can reach up to 10 cm in length and display a vibrant green throughout the growing season. In the fall, these leaves transform into a palette of red, orange, and yellow hues. During spring, as the leaves begin to unfurl, clusters of red-purple flowers appear on long stalks, eventually giving way to brownish-red, winged fruits.
About the genus
