Why the Green Gable™ Black Gum/Sour Gum?

Green Gable™ Tupelo is a dapper new selection of our beloved native Tupelo Tree with upswept branches that give this handsome shademaker a perky, pyramidal habit. Use it to line your driveway in high style, show it off as a street tree for the whole neighborhood to enjoy, or plant a single specimen outside your window where you’ll get to see it every day. You’ll especially want a window seat in fall, when its glossy, deep green foliage turns a radiant red. Faster growing than other Tupelo Trees, Green Gable™ will get right to work at creating a sensation in your garden!

A close relative of the Tupelo Tree of the Deep South, which gives bees the raw material for making the famous “Tupelo Honey,” this species of Tupelo lights up forests and landscapes in a much greater area of the eastern U.S. each fall. It is long-lived and can put on its annual autumnal fireworks for hundreds of years. Green Gable™ Tupelo was selected from a batch of seedlings in 2002 by Tennessee nurseryman, Alex Neubauer. It was named for its tightly pyramidal habit (a “gable” is a peak on the side of a building). In autumn, its leaves turn as red as the hair of the heroine in the Anne of Green Gables story as well.

How to use in the landscape?

Tupelo has many aliases, including “Black Gum,” “Sour Gum,” and “Pepperidge.” If that last one sounds familiar, it’s probably because that’s the tree you see on packages of “Pepperidge”Farm® cookies! (Apparently “Sour Gum” brand cookies doesn’t have the same marketing appeal.) Tupelo’s official Latin name, Nyssa sylvatica, means “Water Nymph of the Forest” and refers to this tree’s fondness for growing in moist to wet soil in the wild. However, it grows just fine in ordinary soil, too.

How To Plant

The Green Gable™ Tupelo is an easygoing, adaptable tree, and it is bound to be planted more when people learn of its many virtues. It’s a great tree for that troublesome low spot in your yard that always stays wet, but it’s equally suitable to average garden conditions, and once established it will only need supplemental irrigation during prolonged periods of drought. It’s also tolerant of salt spray and can be used in coastal plantings, although it does appreciate a bit of shelter from very strong winds. Green Gable™ is resistant to the largely harmless but rather unsightly leaf spot disease that can afflict some Tupelo Trees as well.

How To Water

Water twice weekly for the first 3-5 weeks; then water weekly for the remainder of the year until winter. When you water, water slowly and thoroughly. Watering needs may be altered due to extreme weather conditions.

How To Fertilize

Incorporate Elements Starter Plant food granular form into the soil when planting. If planting in spring or summer start fertilizing late fall using Elements Starter Plant food granular form on an annual basis each late year. Continue this for three years to get your plant well established.

How To Prune

Prune in late winter when needed.

How Does Shipping Work?

Bower & Branch Trees, the real BIG trees, don’t fit in a box! Our large trees require expert delivery and care, that means our large trees are shipped on Bower & Branch trucks. We are the only ones who know how to ship our big and bigger trees and plants with tender loving care.

We deliver your trees and plants directly to your driveway or curbside! Ask Bower & Branch about planting services and rates – we'd be happy to assist in installation.

*Big trees, Size XL (A) and bigger, will take approximately 2 to 4 weeks days to be delivered. - Sizes large (AA) and smaller (Treelings) will be shipped directly to your home by a local common carrier in a plant-safe box.

How Does Sizing Work?

The size of our trees have nothing to do with the container size like you may find elsewhere–big doesn't mean just height - it’s also vigor, age, and overall health.. Other online retailers are going to tell you that a plant is a seven gallon, that means nothing to your tree or plant (or you.)

Our trees for sale online are graded on large, x-large, and even bigger sizes. This is because our trees are sized by their age—the higher the letter, the more mature the tree. The age determines the trees’ overall height, size of the trunk and the overall branch density.

All of these characteristics are what you should be looking for when choosing a tree for immediate impact and instant curb appeal. Our extra-large tree and plant sizes are sure to wow you and your neighbors!
