The Alta™ Southern Magnolia is the perfect choice for limited spaces and smaller gardens, because it has full-sized blossoms on a narrow, columnar tree that is never more than 10 feet wide. The leaves are large, but narrow, keeping the tree neat and in proportion. The 10-inch blossoms spread their broad petals in spring, and bloom for more than two months, releasing a delicious, rich fragrance. This tree is perfect for a lawn specimen in a smaller garden, or for planting against brick walls between windows. In colder areas it can be grown spread out on a sunny wall. It also makes the perfect narrow evergreen screen or informal hedge.

  • Very narrow columnar form
  • Perfect for smaller gardens and smaller spaces
  • Hardy even in zone 6, and warmer parts of zone 5
  • Full-sized magnolia blossoms on a smaller tree
  • Fast-growing potential with good care

Always plant the Alta™ Southern Magnolia in full sun, for the best growth. It grows best on deep, moist but well-drained, acidic soil, but with plenty of organic material added to the soil, and a good fertilizer program, it can be adapted to any well-drained soil. Established trees are moderately drought tolerant, but too much dryness will cause leaf yellowing and reduce flowering. This variety has an unusually fibrous root system, which makes planting easier and reduces the risk of transplant shock.
