The Best Trees for Vibrant Fall Foliage in Tennessee and the Southeast
For no-fail‚ gotta-have-it fall color‚ plant Sugar Maple‚ Red Oak‚ Sassafras or Black Gum․ These trees grow well in Tennessee‚ growing zones 6-7‚ and can provide consistent‚ long lasting fall colors ranging from butter yellow to deep burgundy․ You just have to be sure to match the growing conditions of your soil and sun exposure to the tree species you desire‚ as well as have some patience with the growth rate of your selection․ Below‚ we break down exactly what to expect from each of these trees‚ plus a few others worth considering that often get left off these lists․
Sugar Maple (Acer saccharum): The Gold Standard
Sugar Maple is appropriately named․ In Tennessee‚ from about mid- to late October‚ Sugar Maple displays the full fall spectrum of lemon yellow‚ burnt orange‚ and red so lacquered it seems almost artificial‚ like the autumnal foliage of photoshopped trees․ A mature Sugar Maple reaches 60-75 feet (18-23 m) in both height and width‚ and is not recommended for a small lot in an urban environment because of its large size․
Sugar Maple prefers well-drained‚ slightly acidic soil and either full sun or partial shade․ However‚ if you have wet areas in your yard that hold water after the rain‚ this is not the right tree for you․ Sugar Maples do not like wet feet․ Once established‚ the tree could be expected to grow at a rate of 1-2 feet (0․3-0․6 m) per year․ So you should be prepared to wait 15-20 years before your tree has reached the famous canopy but it will do so and outlive you!
One thing a lot of articles forget: Sugar Maples are not tolerant of road salt or urban pollution‚ and so are best suited to rural or suburban locations rather than on busy streets․ If you live in Nashville or Knoxville proper‚ a Red Maple will have a similar look‚ but be more tolerant of urban stressors․
Red Oak (Quercus rubra): Color That Holds
Red Oak deserves more credit than it usually gets․ While maples go yellowish and then fall all too quickly‚ Red Oak foliage - that deep russet-to-burgundy combination - sometimes stays on the tree for weeks longer‚ even into November․ If you want fall color that doesn’t disappear the moment the first hard frost hits‚ this is your tree․
Red Oaks are more tolerant of varying soil conditions than are Sugar Maples in Tennessee‚ and thus make better street trees in some areas․ Many areas of Middle Tennessee have clay soil‚ which is also suitable․ Plants prefer full sun‚ and will grow 2 feet (0․61 m) or more per year after the seedling stage; they reach 60-80 feet (18-24 m)․ Their deep‚ non-intrusive root systems make them better than shallower-rooted plants near driveways‚ building foundations‚ or septic systems․
Once established‚ a young Red Oak can sustain itself; however‚ for the first two years after planting‚ it should be watered once a week to give it an inch of rain if it has not rained․
Sassafras (Sassafras albidum): The Unpredictable Showstopper
Sassafras (Sassafras albidum) is the tree nobody looks for‚ and then it steals the show․ What sets it apart is the variety of shapes on its leaves: oval‚ mitten‚ or three-lobed․ In fall‚ all these turn slightly different colors‚ sometimes even on the same branch․ Look for the sassafras‚ which is mainly yellow or orange․ Depending on sun exposure and weather‚ red and purple are also more or less represented․
At only 30-50’ tall‚ it is a more manageable tree in the average suburban lot compared with many other oaks or maples․ It tolerates the poor sandy soils better than most other trees with good fall color‚ but prefers slightly acid to neutral or alkaline soils․ Sassafras can spread through root suckers and may form a large colony‚ so it may not be the best choice for a small yard where you want a small tree as a specimen in its own right rather than a grove․
Black Gum (Nyssa sylvatica): The Underrated Pick
Although most top ten fall foliage lists end with maples and oaks‚ Black Gum deserves inclusion as it may be the most consistent of the early fall trees․ In Tennessee it turns early to mid-September‚ weeks before most of the others begin to change color․ The leaves can be scarlet‚ purple‚ and orange‚ all on the same tree․
Black Gum tolerates wet soil better than Sugar Maple or Red Oak and can be planted in low spots of yards where these species would fail․ Its only drawback is that it becomes established slowly (less than 1 year of height growth per year) compared to other trees‚ but it is long-lived and low-maintenance․
Quaking Aspen (Populus tremuloides): Better for Higher Elevations
Quaking Aspen deserves mention for its beauty‚ providing shimmering golds and leaves that flutter even on still days like few other trees․ However‚ for all its beauty‚ let’s be honest; it is a marginal performer in the lower elevations and hot summers of Tennessee․ If you are in the valley and you want that look‚ a Tulip Poplar might be a better choice․ If you are at a higher elevation‚ or some cooler microclimate and you want a nice golden-yellow tree‚ then you could use this․ This Tulip Poplar is well adapted to Tennessee and it has that golden yellow look․
Choosing the Right Combination for Your Yard
Another strategy is to stagger your color․ You could pick a Black Gum for early‚ a Sugar Maple for peak in mid-October‚ then a Red Oak to get you nearly into December․ This can create stretches of color from September through November instead of just three days․
At TN Nursery‚ many of these varieties are actually grown here by us as regionally-adapted stock‚ meaning the trees are already acclimated to Tennessee soil and weather patterns rather than shipped in from a nursery in a completely different climate zone․ That matters more than people realize․ A tree grown in Southeast conditions establishes earlier and tolerates our summer humidity and occasional winter cold snaps with far less transplant shock․
A Few Practical Notes on Planting for Fall Color
Timing is also more important than most guides have you believe․ On hot July and August days‚ plant roots have to be recovering from transplanting‚ not being pushed to the point of death․ Do so in early fall or early spring and water well rather than with light daily sprinkles‚ to create deep rather than shallow roots that can more easily survive drought․
“The first year‚ avoid heavy fertilizing․ At this time the food of young trees should go to the root and not to the top‚ and too much nitrogen is not conducive to strong color․ A basic mulch‚ not closer to the trunk than 3 or 4 inches‚ will do more for the health of a young tree than most fertilizer schedules ever will․”
