Tulip Poplar has gone on a diet! The pear-shaped American shade Tree has gotten a sleek and slim new look. Arnold Columnar Tulip Poplar shoots arrow-straight out of the ground, rising up, up, up, but never spreading out very wide. In many years, it may reach 60 feet tall but only 20 feet wide. You can plant this noble specimen as a street Tree, where there are no power lines overhead, or use it as a defining structural element in a formal garden. A pair of Trees can frame a pretty view in an enchanting way. So chic!

The Story

We can only imagine what they early settlers and the Native Americans thought when they first saw our country's enormous old-growth Tulip Poplars. Some of them 200 feet Tall (and with trunks 10 feet wide), they were the tallest deciduous Trees in North America. Tulip Poplars grow wild from Michigan to Vermont and south to Missouri and Florida. Arnold Columnar Tulip Poplar gives homeowners without loads of real estate the opportunity to grow this regal native Tree. No one is sure where exactly it originated, but there are some grand specimens at Harvard University's Arnold Arboretum, hence the name. 

The Details

When nights get frosty, Arnold Columnar Tulip Poplar transforms itself. The bright green leaves turn glowing gold, and the whole Tree blazes like a candle flame. It will light up the neighborhood!

How to Grow

Arnold Columnar Tulip Poplar will become a tall Tree, so give it plenty of vertical space! It likes a location in all-day sun or partial shade and appreciates regular water. Mulch well and use the Bower & Branch Elements® Watering System to ensure proper moisture levels during the critical establishment period. This is a pretty carefree Tree, but one problem that may strike is aphids. In large numbers, aphids can spur an unsightly sooty mold to form on the leaves. Just make sure to plant the Tree away from the house, car, and patio. Don't use pesticides on the aphids, because bees and butterflies also rely on this Tree!
