Gardeners' Notes:

Positive lehua_mc On Nov 7, 2009, lehua_mc from Portland, OR (Zone 8b) wrote:

Small, slow growing, trouble free. The burgundy color is a bit dull in the peak of summer, with a little edging of green, but the fall color is spectacular. It's a color of hot vibrating red that glows in gray fall. Leaves out a bit late in spring, allowing the under canopy to be filled with bulbs. Keeps its leaves through November here.

A lovely mounding and weeping japanese maple. Leaves are deep purple all season and turn scarlet in autumn.
