Acer pseudoplatanus
'Leopoldii'
Leopold Sycamore Maple
Mike's
Opinion
"
A European cultivar that is seldom used in Ontario for what reason I am not sure. A. pseudoplatanus can reach a height of 20 m and is a broad, dense canopied tree. Since it occurs in lean, often poor soils it can be used in similar situations on the landscape. A wonderful tree where room permits such as parks and institutional settings. Best planted where the full form of the tree can be appreciated. This cultivar is supposed to have pink in the leaves, I have never seen this and in fact believe that the cultivar Leopoldii could be confused with 'Variegatum'.

| Shape |
| Large rounded crown. |
| Growth |
| Fast |
