The Ojishi is a rare dwarf cultivar not known to many . In common terms it is known as the male Lions mane or head. It is a relative smaller version of the more widely known Shishigashira which in common terms is known as the female Lions mane of head. It is special in every sense. It stays small but unlike many smaller dwarfs is not terribly bushy or stick like it is a “tweenner” , having a miniature branched bush look.The leaves go tightly all the up branches , similar to the Shishigashira . But seem to be both thicker and tighter. The above photo is one I have in my yard for 3 years that is probably 6 years old. As you can see the old growth is dark green and new a yellow green.
It can be placed anywhere where space is at a premium and can take full sun or part shade or full shade with only the color effected ( less sun less color as with most JM’s).. it grows well without leaf burn anywhere. . Each branch is full of small curly stiff leaves all from base to top each one with great texture and form . It is super hardy I would think down below -20 and leafs out late avoiding late frosts or freezes. Ojishi holds it color well into late fall with a nice mix of yellow, red, and orange.
For anyone wanting a hardy dwarf of outstanding distinction and form, or anyone with a Shishigashira that wants a little brother to keep it company, this is the perfect tree for you. HIGHLY underrated, unknown to most, and rarely available, Ojishi should be on your next list of “must have “dwarf Japanese maple cultivars.
