![]() Numerous cloudy days during fall may result in more golds and yellows. The entire growing season contributes to the health of trees and their colors, but bright fall sunlight produces the most brilliant colors. Perfect foliage follows the Goldilocks principle: that the weather has not been too hot, too cold, too wet, nor too dry, but just right. But environmental conditions and weather play into the timing of foliage change. Two constants are 1) day length, which is the primary factor influencing when leaves change, and 2) the tree species, which is the main factor influencing how the leaves change through a predictable color progression. Different species turn different colors, and those species turn at different times in the fall. Locally, there is white ash, American elm, basswood, and hop hornbeam.Ī common question this time of year is, "When is peak foliage going to be?"”Answering this question is tricky, because while some factors that play into the timing of foliage are constant, many change. Sugar maple and beech dominate this forest other common trees include yellow birch, red maple and black cherry. The northern hardwood forest is the predominant forest in the Catskills and includes tree species with the most dazzling colors. Oaks will be the last to change, with red oaks turning red and chestnut oak golden to bronze hues. We generally recognize “peak foliage” as the period when maples are in full color. Red maples generally will turn red, while their cousins, sugar maples will show a spectrum of yellow, orange and red. One of the earliest wide-spread colors that we see is yellow from ash, yellow birch and black birch. Carotenoids show up as yellow and anthocyanins show up as red. The reduction of green chlorophyll in the leaves allows other colored compounds to show through. As the days shorten, the trees stop producing chlorophyll and store valuable sugars and nutrients for the following year. Verticillium wilt may occur on poorly drained soil types.Why do leaves change colors? Pigments are most responsible for the color changes we see in autumn: chlorophyll, carotenoids and anthocyanins.Ĭhlorophyll allows plants to produce sugars from sunlight. Growing in full sun or shade, this species will tolerate a wide variety of soil types. Birds and squirrels fest on the fruit produced by this tree. This cultivar is considered one of the best in the trade for the temperate zone.įruit is the familiar two-winged samara as with other maples. The Canadian national emblem is often equated with the shape of the sugar maple leaf.ĭuring the summer the leaves are dark green (pale beneath), but by the fall they turn their brilliant shades of burnt orange or red. Sugar maple leaves range in size from 3”-6” across. Sugar maple can be distinguished from Norway maple by having rounded tips on the lobes of the leaves. They are often referred to as being star shaped. ![]() Leaves are arranged oppositely, are simple, and have 3-5 lobes. It features a symmetrical canopy with a regular (or smooth) outline. Green Mountain sugar maple develops into a stately tree that grows 40’-60’ tall and 35’ wide at maturity. On the east coast of the United States the trunks of sugar maples are tapped in the winter for their sap which is later boiled down to make maple syrup. Description The main ornamental feature of Green Mountain Sugar Maple is its brilliant red, yellow, or orange fall color that develops in the cooler part of its range. ![]()
