Well, I really did not know how tall a Christmas tree could be so I looked it up and found this.
Excerpt:
Phoenix, Ariz.
Height: 110 Feet
This might surprise you, but a Christmas tree at an outlet mall in Phoenix, Ariz. holds the title as tallest fresh-cut tree in America. To give you a reference point, this mammoth evergreen surpasses Rockefeller Center's iconic Christmas tree by 30 feet. This 110-foot-tall white fir tree towers over Dress Barn and Yogurberry and the many other stores in the Outlets at Anthem mall. It's garnished with 120 strings of LED lights, oversize ornaments and a three-foot-tall copper star. And in case you're feeling sad that the Earth has lost one more gorgeous pine tree, take heart that 12 were planted in this one's stead.
Dortmund, Germany
Height: 147.6 Feet
If you find yourself in Dortmund this December, you'll likely see the flickering lights of its enormous Christmas trees before you notice anything else about the eighth largest city in Germany. Yes, that's right: trees. The 148-foot-tall spectacle is actually the sum total of 1,700 individual red spruce trees, stuffed and stacked into a frame. Tens of thousands of lights, as well as 20 candles, create a glowing wintry scene, which you can enjoy in the Hansaplatz (market square). While admiring Dortmund's Christmas spirit, you can also partake in some holiday shopping. Hansaplatz also serves as the location of a bustling Christmas market encompassing more than 300 stalls, selling yuletide treats, and handcrafted gifts.
