Magnolia grandiflora

Species (evergreen)

V Written by Editorial Team · Updated January 2026

An evergreen species from the southeastern United States, this magnolia is grown for huge, creamy white flowers and lustrous foliage. It forms a pyramidal to rounded tree that suits large properties and parks. Individual blooms can reach 8 to 12 in (20 to 30 cm) across with a rich perfume. It performs best in warm climates with long summers and mild winters in USDA Zones 7 to 9. Give it room to mature because lower limbs often sweep the ground. Plant where soils are moist and well drained and where winter winds are limited.

Care in one minute

Plant in full sun to part shade in moist, organically rich, well‑drained, acidic soil.

Water regularly the first two growing seasons; keep an even soil moisture.

Mulch the wide root zone 2 to 3 in deep; avoid soil compaction over roots.

Fertilize lightly in spring only if soil tests indicate need.

Prune minimally right after bloom to raise canopy or remove crossing wood.

In colder areas, site in a protected spot and consider hardier selections.

Watch‑outs

  • Too large for small yards; needs ample space.
  • Leaves and spent flowers drop through the season and are slow to decompose.
  • Can become chlorotic in alkaline soils; prefers acidic conditions.
  • Scale insects can occur; monitor and manage as needed.
  • Borderline hardy north of Zone 7; select hardy cultivars if needed.
