Magnolia Exmouth
Magnolia Exmouth

A medium to large tree, Magnolia grandiflora ‘Exmouth’ has a more upright habit rather than spreading and this makes it useful as a screening tree.

From the Southern states of North America,  over time in ideal conditions  it can reach 20m + however in cultivation usually growing to around 10m in height.

Magnolia Exmouth Varieties

Be aware that two forms of this tree are available the second is Magnolia Grandiflora ‘Exmouth’ (Compact Form) and is usually what is sold, but not always labeled as such.

This is a M. grandiflora variety  with a bushier habit with broader foliage than ‘Exmouth’ itself, with a wonderful bright cinnamon felt or indumentum on the underside of the leaves.

With glossy green foliage backed with felt copper colour, the flowers are probably the most fragrant of all of the evergreen magnolias, large and a slightly creamy white. One of the really appealing factors is the size of the flowers. As a matter of interest this cultivar was developed in the UK over 100 years ago

Care

  • Be a little patient if you are buying a small specimen as they can take 7 – 10 years to flowers.
  • Plant in a deep moist but well drained soil, full sun to part shade, the warmer the climate the more shade.
  • Mulch to retain moisture and maintain a cool root run.
  • Water in well when planting using a liquid seaweed fertiliser.
  • Stake to ensure a good upright habit.

Once it settles in this is a tree that requires little extra care and only watering in very dry periods. Replenish mulch each spring while the soil is still damp.

Root system

Like all Magnolias, Exmouth is a little shallow rooted so it does not like to be disturbed by digging, we suggest mulching to keep weed free and planting some hardy small bulbs beneath, crocus, daffodils and the like.

Successful in large containers as long as moisture and fertiliser are maintained. Can be pruned to maintain shape
