Cultivar Description & Characteristics
Osakazuki is universally acclaimed as having the most brilliant, fiery red autumn foliage of any Japanese maple. The upright, vase-shaped tree features large, deep green leaves throughout the spring and summer months. When autumn temperatures drop, the entire canopy transforms into an incandescent, glowing crimson red that stops traffic. It is an essential centerpiece tree for any landscape designer prioritizing autumn color.

Growth Habit & Size
Upright
Upright tree with a substantial mature canopy.
What do these growth habit terms mean?
More than one term can apply. Branch direction, crown shape and size describe different characteristics, and the outline can change as a tree matures.
- Upright
- Main stems and branches emphasize upward growth. An upright tree can still develop a broad canopy.
- Spreading
- Branches extend outward to form a broad canopy. The tree does not have to be wider than it is tall.
- Weeping
- Branches or branchlets arch or hang downward. The tree can still have an upright trunk.
- Rounded
- The crown has a rounded outline. This describes the overall shape rather than the direction of each branch.
- Dwarf
- A cultivar with a smaller natural stature than typical forms of its species. Dwarf describes size, not branch direction or a fixed height limit; it does not automatically mean slow growth.
For example: Bloodgood can grow upright while developing a broad, rounded canopy with spreading branches.

The story behind Osakazuki
- Cultivar origin
- Japan; Minier Nurseries reports it was known near Osaka before 1882
'Osakazuki' is an old Japanese maple cultivar whose original selector and parentage remain undocumented in the reviewed sources. Minier Nurseries reports that it was known near Osaka before 1882. This establishes a reported historical presence, not a selection date or first commercial introduction year. Bean's account, reproduced by Trees and Shrubs Online, explains that the name appeared in catalogs before Koidzumi's 1911 botanical description. It also records longstanding confusion: more than one clone, and possibly seedlings, have circulated under the name, with differences already noted in 1933. Consequently, a later botanical description should not be mistaken for the cultivar's origin. The familiar garden form is distinguished by substantial seven-lobed leaves and exceptionally vivid red autumn color.
