Magnolia sieboldii (Oyama Magnolia)
Oyama Magnolia, Korean Mountain Magnolia, Siebold's Magnolia
A classic beauty, Magnolia sieboldii (Oyama Magnolia) is a vase-shaped, deciduous shrub or small tree boasting splendid flowers in late spring to early summer and sporadically throughout the rest of the summer. Emerging from egg-shaped buds, nodding or pendent, cup-shaped fragrant white flowers, 4 in. across (10 cm), with prominent crimson stamens, can be admired. They are followed by showy, pink oval fruits, 3 in. long (7 cm), which split open in the fall to reveal orange to red seeds. The foliage of broad elliptic green leaves, 3-6 in. long (7-15 cm), turns golden yellow in fall. Oyama Magnolia grows as an understory tree or large shrub in the wild. Small-statured, with no serious disease or insect problems, this Magnolia is a good choice for small gardens where it will make a charming statement growing as a central feature.
- Grows up to 10-15 ft. tall and wide (300-450 cm).
- Performs best in part shade in moisture-retentive, organically rich, well-drained neutral to acid soil. May be grown in full sun in cool summer areas as long as the soil is constantly moist. Intolerant of poor soils. Plant in an area that is protected from strong winds to help the flowers last their longest.
- A beautiful addition to city gardens, cottage gardens, woodland gardens, patio containers, and small gardens.
- No serious pest or disease issues. Keep an eye out for capsid bugs, snails, coral spots, gray mold, and honey fungus.
- Pruning is best done after flowering when in full leaf.
- Propagate by seed, semi-hardwood, and softwood cuttings.
- Native to Japan, southeastern China, and Korea.
