Ojishi is dark green and stays small. It does very well in heat and full sun much like our shishigashira. Our Ojishi is approximately 20 years old. I've had it in the same spot for 10 years and it's required minimal pruning. Probably the lowest maintenance Japanese maple in my collection. Here's a quick photo taken this morning. To compare color/texture Mikawa Yatsubusa is in the background upper right corner of the photo.
