Description and Growing Information

General DescriptionThis cultivar is a dwarf plant as it does not grow taller than 3.4 m high. It is known for its fire red leaves that hold their colour for most of the year and for its thick and dense foliage.
ID CharacteristicUniquely red leaves that hold their red colour through the spring summer and fall. This cultivar also grows slower and grows more dense than other Japanese maples.
ShapeVery low canopy.
LandscapeCan be used as a potted plant or planted in an outdoor landscape. It is not commonly used in general landscapes as it is not very pollution tolerant and requires very moist conditions.
PropagationGrows best in moist, well-drained low-acidic soils. Thrives in morning sun and afternoon shade conditions. Should be planted in the fall during the dormant season, since maple roots grow throughout the fall and winter months. Ensure that the temperature does not drop below freezing.
PestsLeaf cutters, rollers and aphids. No known diseases.
HabitatHorticultural origin.
Bark/Stem DescriptionTrunk is usually one single trunk with many branches. It can be multi trunked but is very uncommon.
