- - - -
Acer pseudoplatanus is a tree.
Acer pseudoplatanus was described by Carl Linnaeus in 1753. The name is considered as validly published.
The trees reach heights of 20 to 30 metres, the main growing season is in spring and summer. They have a rounded to broadly spreading canopy. The plants reach a width of 10 to more than 15 metres.
Wood and Bark
Acer pseudoplatanus is deciduous. The green, simple leaves are opposite. They are palmately lobed and petiolate with lobate margins and palmate venation. The foliage is dense in summer and porous in winter and turns an attractive yellow in autumn.
Flowers and Fruits
Acer pseudoplatanus produces racemes of pendant, greenish yellow five-stellate flowers from May to June. The plants flower on older shoots. They are dioecious, pollination takes places by allogamy through animals.
The trees produce an abundance of ornamental green schizocarps from spring to summer.
The plants form shallow roots.
Acer pseudoplatanus is native to Europe and Southwest Asia.
The trees prefer a sunny to half-shady situation on fresh to moist soil. They prefer sandy-loamy, gritty-loamy, sandy clay, loamy clay or peaty soil with a pH between 5,8 and 7. The plants need a soil depth of at least 1.22 metres for good growth. They tolerate temperatures down to -35Â°C (USDA zone 4) and need a frost-free period of at least 20 weeks. The plants are suited for spring protection, bank protection in softwood areas along wide flowing waters and bank protection in hardwoos areas along wide flowing waters.
Classification after Prof. Dr. Sieber
- open areas
Tolerance of special soil conditions
- none: anaerobic soil
- low: calcareous soil
- medium: soil salinity, drought
- high: city climate, road salt
Suited for windbreaks and soil protection and for noise and dust protection, as well as suited as avenue tree, specimen plant, greenery along roads, bee pasture, bird pasture and as plant providing shelter for birds.
Maintenance and Propagation
The plants usually need very little maintenance.
Propagate by sowing. The seeds require vernalization. Also by cuttings.
