Growing Zones 4-9
It may not be a famous jazz musician or a world-renowned space traveler, but the Armstrong Maple Tree (Acer x freemanii 'Armstrong') is certainly a winner as far as trees go!
Like most Maple trees, Armstrong starts spring off by budding large and luscious green leaves that stick around all through summer. Once the temperature cools off, those same leaves turn the brilliant red that's become a staple of Maple trees.
However, unlike other trees, Armstrong Maple has branches that grow upwards at an impressive angle. This gives the tree a unique look and makes it the perfect specimen for spaces too narrow for a regular Maple tree with an outward spread.
Armstrong is even pleasing to look at during the colder months of winter as its cross between the Red Maple and Silver Maple has left it with stunningly silver bark that seems to shine when the tree is bare.
Those aren't the only great traits Armstrong got from its two parent trees. The Silver Maple gives the tree its rapid-growing nature and its adaptability to most soils while the Red Maple gives it its fantastic fall color and solid form. The hybridization of the two trees in 1933 truly gave the gardening and landscape world a perfect urban Maple tree.
Landscape Application:
Whether near a street in an urban setting, filling in a corner of a rather small yard, or acting as a privacy screen on the edge of your property, you can depend on Armstrong to be a beautiful, and efficient, space-saving Maple tree!
Try an Armstrong as a fantastic shade tree in a smaller yard, reducing your cooling bill in the summer, or shading your sunbaked outdoor garden rooms and spaces! Growing 50 - 70 feet in height but only spreading 15 - 20 feet wide, Armstrong is almost columnar!
Need a dramatic front yard focal point? Spring, summer, and fall color plus wildlife support and mighty winter presence, park an Armstrong in your front yard so it can grow to full height in all its glory!
- Classic Red Maple Leaves in Fall
- Unique Upward Growing Branches
- Perfect for Narrow Yards or Small-Spaced Gardens
- Stunning Silver Bark for Winter Interest
- Street Trees, Front Yard Specimens & Shade
#ProPlantTips for Care:
When deciding where to plant this narrow deciduous tree, you won't have to think about the soil much as it is not picky. It does appreciate being planted somewhere it can bask in the sun all day long. Armstrong tolerates both flooding and drought for short periods of time very well, making it the perfect tree for places with finicky weather patterns.
Plant in full sun and well-drained soil with regular water access their first year, but can be quite drought tolerant once settled. Mulch keeps your tree stress-free and pruning when dormant keeps your trees trim form.
- Full Sun
- Well-Drained Soil
- Moderate to Low Moisture Needs
- Prune Late Winter
- Tolerates Some Drought & Flooding
Narrow spaces and small yards are Armstrong Maple's best friend! Don't let space keep you from enjoying a Maple tree and order one of your own today! Now available at NatureHills.com!
