Galaxy Magnolia

Galaxy magnolias make excellent street trees under power lines.

Scientific Name:
Magnolia ‘Galaxy’

Under Power Lines:
Yes—this tree is approved for planting under power lines.

Street Tree Planting:
Yes—minimum planting strip width of 5 feet. If planting a street tree, you must be approved for a permit.

Gorgeous dark red-purple flowers and a narrow upright form make it an excellent street tree, especially under overhead wires. Great in narrow spaces and smaller landscapes!

Mature Height:
25 feet

Mature Spread:
25 feet

Deciduous tree with large green leaves.

Red-purple and slightly fragrant blooms appear in late spring, later than most other magnolias.

Beautiful late spring blossoms

Partially sterile, but may occasionally produce fruit.

Cultural Notes:
Very adaptable to a wide range of soil and cultural situations, but grows best in full sun and rich well-drained soils.

Potential Problems:
Magnolias have fleshy roots easily damaged, so it's important to limit digging and gardening under the established tree. Spreading a nice 2-4 inch layer of mulch around the base of the tree can help protect the roots.

Minimum Planting Distances:

  • 15 feet from house or building
  • 3 ½ feet back from the face of the curb
  • 5 feet from underground utility lines
  • 10 feet from power poles
  • 7 ½ feet from driveways (10 feet recommended)
  • 20 feet from street lights and other existing trees
  • 30 feet from street intersections
