Magnolia × soulangeana
Overview
The Saucer Magnolia is one of the most popular ornamental flowering trees in the world. A hybrid created in the early nineteenth century by crossing Yulan Magnolia (Magnolia denudata) and Lily Magnolia (Magnolia liliiflora), it is prized for its large, tulip-shaped flowers that bloom before the leaves emerge in spring.
Its spectacular floral display has made Saucer Magnolia a favorite in gardens, parks, campuses, and arboretums. Large pink, purple, and white blossoms often appear when few other trees are in bloom, making the species one of the earliest and most striking signs of spring.

Origin and History
Saucer Magnolia is a cultivated hybrid developed in France during the early 1800s. It combines characteristics of two Asian magnolia species and quickly became one of the most widely planted flowering trees in Europe and North America.
Numerous cultivars have since been developed, offering variations in flower color, size, shape, and bloom time.
Within the Marshall University Arboretum, Saucer Magnolia is classified as a Non-Native species.
Ecology and Wildlife Value
Saucer Magnolia provides valuable early-season resources for pollinators.
Its flowers attract:
- Bees
- Beetles
- Other pollinating insects
The tree’s branching structure also provides:
- Nesting opportunities for birds
- Seasonal shelter
- Shade and visual diversity within the landscape
While it does not support the same ecological relationships as many native trees, it contributes to pollinator activity and landscape biodiversity.
Human Uses and Cultural Significance
Saucer Magnolia is grown almost exclusively for its ornamental value.
The species is valued for:
- Spectacular spring flowers
- Early bloom season
- Attractive growth habit
- Four-season landscape interest
- Historic horticultural significance
Because of its exceptional floral display, Saucer Magnolia is commonly planted as a specimen tree where its blossoms can be fully appreciated.
Saucer Magnolia at Marshall University
Saucer Magnolia contributes spring color and ornamental beauty to the Marshall University Arboretum. Its large blossoms provide one of the most noticeable floral displays on campus, attracting attention from visitors throughout the blooming season.
As a non-native ornamental species, Saucer Magnolia demonstrates the influence of cultivated landscape trees on the campus environment and complements both native and introduced flowering trees within the arboretum collection.
