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

🇨🇦 🇺🇸 🇲🇽 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!
