Botanical description and morphology of Acer saccharum
El Acer It is a medium to large tree that can reach heights of over 30 meters in optimal natural conditions, although some mature specimens have reached over 40 meters in America. It has a crown dense, oval and wide, with main branches that extend in a columnar manner and offer an imposing silhouette in the landscape.
- Sheets: They are large, 12-15 cm long and sized in diameter, palmately lobed, with five main lobes, the three central ones usually more prominent and with sharp apices. The base of the leaf is heart-shaped, the upper surface is a glossy dark green color while the underside is paler and may show light hairiness. autumn, the leaves display spectacular shades of yellow, orange and red, making the sugar maple one of the most valued trees for providing seasonal color in parks and gardens.
- Flowers: They are small, hanging, and yellowish-green in color. They generally appear in clusters before or simultaneously with leaf budding in spring. Although inconspicuous in appearance, they are important for pollination and fruit formation.
- Fruit: The characteristic fruit is a disamara, that is, a double-winged seed, whose wings are parallel and facilitate wind dispersal. The flat, light seeds ripen in late spring.
- Cortex: It has a smooth texture and a grayish-brown color when the tree is young, becoming more cracked and scaly with age. This bark has traditionally been used as an indicator of tree health and maturity.
- Yolks: The buds are pointed and brown, other characteristics that help identify the species, especially in winter.
Natural distribution and climatic adaptability
Acer It is native to the temperate forested regions of Eastern Canada and Eastern United States, although it has been adapted and planted in numerous areas of the northern hemisphere thanks to its resistance and ornamental value.
- It develops optimally in mixed deciduous forests, forming dense stands and contributing to the structure of the forest canopy.
- It tolerates a wide range of temperate climates, but prefers cold winters and mild summers.
- It accepts very diverse soils, although it has a preference for fresh, deep, well-drained, and slightly acidic soilsIt does not thrive in excessively wet soils or where water remains stagnant and is sensitive to road salt and soil compaction under pavements.
- It is resistant to wind, urban pollution, cold, proximity to the sea and snowfall, making it an excellent choice for cities, avenues and peri-urban areas.
Annual cycle, growth and longevity
The sugar maple is a tree deciduous that loses its leaves during the fall-winter and sprouts again in the spring. Its growth is characterized by being relatively fast in the early years under ideal conditions, slowing as the tree matures. It can live several centuries, with specimens in North America that have lived for over 200 years.
- You can reach heights between 20 and 35 meters in natural environments and develop a robust, straight trunk up to 1 meter in diameter.
- The canopy, especially in isolated specimens, spreads widely, providing dense, cool shade in summer, which gives it great landscape value.
Varieties, subspecies and etymology
Acer It comprises several subspecies and varieties with slight morphological and ecological differences, adapted to different geographical areas:
- A. saccharum subsp. floridanum
- A. saccharum subsp. grandidentatum
- A. saccharum subsp. leucoderme
- A. saccharum subsp. nigrum
- A. saccharum var. rugelii
- A. saccharum var. schneckii
- A. saccharum var. sinuosum
- A. saccharum subsp. skutchii
As for its scientific name, Acer comes from the Latin 'acer', which means sharp, alluding to the steely tips of its leaves or the hardness of its wood, while saccharum means 'sugar', clearly referring to the high sugar content of its sap.
Outstanding properties and benefits of Acer saccharum
