Star Magnolia

Magnolia stellata

The Story

Plant Bio

Magnolia stellata, the star magnolia, is a slow-growing multi-stemmed deciduous shrub or small tree from Honshu in Japan, reaching fifteen to twenty feet with a rounded to pyramidal outline. Smooth mottled grey bark carries furry buds through winter, and star-shaped flowers of twelve to twenty narrow white tepals open on bare stems in very early spring.

It flowers earlier than any other magnolia, which is both the attraction and the risk: a late frost turns the open blooms brown overnight. Plant it away from an east-facing wall, because it is not the frost itself but rapid thawing in early morning sun that does the damage — a north or west aspect lets frosted buds thaw slowly and often escape.

Uses & Benefits:

Ornamental UsesStar-shaped white flowers on bare branches at the very start of spring, on a neat small-garden frame.
Practical UsesSmall and slow enough for a modest garden, unlike most magnolias, and needs almost no pruning.
Ecological BenefitsButterflies pollinate the flowers, and birds and small mammals take the seed from the cone-like fruit.

Planting

How to Grow

  1. Plant in full sun to partial shade, sheltered from wind.
  2. Avoid an east-facing position where sun hits early.
  3. Give it moist, humus-rich, slightly acid soil.
  4. Water through the first few summers to establish it.
  5. Mulch over the shallow roots but keep it off the trunk.
  6. Prune only to remove dead wood, straight after flowering.

Pro Tip

Frost damage comes from fast thawing, not the freeze — a north or west aspect lets frosted buds warm slowly and often saves the display.
