Its relatively rapid growth makes it highly appreciated in both public and private gardening.
Main botanical characteristics of Acer truncatum
The bearing of the Shantung Maple It typically grows between 8 and 10 meters tall under normal conditions, but can reach much larger heights in its native habitat. Its grayish to dark brown bark is deeply fissured, giving it a rustic appearance during the winter when the tree is leafless.
The branches, often twisted and close together, are accompanied by glabrous twigs purple in color when young. The foliage is one of the most striking aspects: The leaves have between 5 and 7 lobes They are oval to triangular in shape, with entire to lobed edges, and reach 6 to 12 cm in length. The upper surface is bright green with purple hues, and the underside displays tufts of small hairs in the axils of the veins.
The 5-8 cm long, latex-filled petiole supports the leaves, which transform into shades of yellow, orange, and red in autumn, creating a striking visual spectacle. Flowering occurs before the leaves appear, in terminal corymbs of yellowish-green flowers with eight stamens. The fruits, called samaras (wing-shaped), they measure about 3 to 4 cm and appear in pairs forming a right angle.
Featured varieties and cultivars
The genus Acer includes numerous species and within the Acer truncatum we find cultivars of great interest, such as the well-known 'Akikaze-nishiki'This variety is characterized by its panache foliage Green and white, with pink hues in young leaves, and a generally multi-stemmed appearance, it can reach about 6 meters in height and width at maturity. During spring and summer, its color can vary drastically from one specimen to another, presenting almost completely white or only partially variegated leaves.
Like the type species, this cultivar is very hardy, tolerates slightly calcareous soils, and adapts to both full sun and partial shade. In autumn, the change in color of its leaves It is especially attractive, turning into intense yellow, orange and red tones.
Optimal growing conditions

It is advisable to monitor humidity, especially in the first few seasons after planting.
Climate: It tolerates a wide range of temperatures and is very cold resistant Extreme, withstanding significant descents without damage, making it an ideal choice for climates with harsh winters. It also withstands heat and moderate wind well.
Multiplication and planting
The most common method to multiply Acer truncatum is by sowing seeds, harvesting the mature samaras in the fall and planting them after a period of cold stratification. It's advisable to choose a permanent location to plant the young specimen, as transplanting well-rooted trees can be tricky due to their extensive and deep root system.

When planting, it is important to respect an adequate distance from other trees and buildings, since their cup can expand considerably over the years.
Essential care for good development
- Pruning: It is recommended to carry out a formative pruning in the first years to define the shape and remove dry or misaligned branches. Subsequent maintenance is minimal.
- Subscriber: An annual application of organic fertilizer in spring promotes vigorous growth and denser foliage. It can be supplemented with balanced fertilizers if the soil is poor.
- Control of pests and diseases: Acer truncatum is relatively hardy, although it can be attacked by mites, aphids or mealybugsRegular monitoring and the application of organic treatments are usually sufficient to keep pests under control.
