Introducing the Acer palmatum ssp. matsumurae 'Suminagashi,' also known as the Sumi Nagashi or Suminagashi Japanese Maple. This stunning tree is hardier than green-leaved types and boasts sensational fall colors. Its spring foliage is a bright purple-red, black red, or maroon that transforms into green red or brown red in late summer and then a gorgeous crimson in the fall. With a strong growth that reaches up to 4 meters in height, this large-leafed cultivar is ideal for landscape design, and its winter silhouette and smooth gray bark add interest during the off-season. Like all seed collected from cultivars, the resulting seedlings may not resemble the mother tree, but red-leaved varieties produce a high proportion of red-leaved offspring. Order fresh green seed today to add this stunning maple variety to your garden or landscape.
