Korean Maple is a compact and delicate tree known for its small, ornamental shrub-like stature and fall color. Korean Maples are great substitutes for Japanese Maples because they’re more cold hardy. It may also be known as Purplebloom Maple as a reference to its unique minute red-purple flowers when new foliage emerges in spring.
This small specialty maple is an ideal substitute for the coveted Japanese Maple. Korean Maples set themselves apart with their cold tolerance.
Korean Maples are generally grown for their attractive palmately foliage, shape, and stunning fall color. With an intense barrage of orange, yellow, and red it’s sure to be an outstanding addition to many landscapes.

Regular watering, especially through drier months is vital. Korean Maples will thrive in organically rich soils with good drainage. Avoid waterlogged sites.
Korean Maples don’t require much pruning. Remove any damaged, dead, or diseased branches during the dormant season. It’s thin bark can be easily damaged if you treat it roughly or plant in an overly windy spot.
Korean Maples have no serious insect or disease problems. It’s susceptible to stem canker, leaf spots, and anthracnose, but these common ornamental diseases rarely cause mortality.
