Ötzi the Iceman carried a container with freshly-picked 🇳🇴 🍁︎ Norway maple leaves, presumed to have insulated burning charcoal embers. [1]

In North America, often planted in new housing developments, one in each front yard, due to its excellent shade (which stays into Autumn), and nothing eats it.  Unfortunately, it does not turn the pretty reds and yellows and oranges of the native maple trees.  And it fails to feed the population of local native 🐞︎🐛︎🐜︎🐝︎ insects, so your yard is relatively sterile!

Plant nurseries have created many cultivars of Norway maple, selecting for distinctive leaf shapes or colorations.  For many varieties, during the first month of the growing season, the leaves are burgundy.  Two of our authors have a 🇳🇴 🍁︎ Norway maple  Acer platanoides 'Schwedleri' or 'Crimson King', which gives very nice color.

Although here in 🇨🇦 Canada and 🇺🇸 USA, the tree provides no ecological functions/ecosystem services at all.  Native alternatives (Missouri Botanical Garden).   Native alternatives (Pennsylvania) (.pdf page 4).   Native alternatives (Brooklyn Botanic Garden).
