Outstanding Qualities

Oyama magnolia is a superb plant for the woodland as it is accustomed to growing beneath the forest's larger trees. Its splendid flowers are produced through May and June, with a trickle of blossoms through the rest of summer. The nodding flowers emerge from egg-shaped buds, a peek inside them reveals their rose-red stamens -- and a sniff reveals their fragrance. The oval fruits turn carmine in autumn and are ornamental against oyama magnolia's golden fall foliage. Combine Oyama magnolia with other woodland shrubs, such as Enkianthus campanulatus 'Red Bells', Fatsia japonica and Mahonia nervosa. Consider also shade-loving perennials such as Carex morrowii 'Ice Dance', Dicentra spectabilis 'Gold Heart', Hakonechloa macra 'Aureola', Hosta 'June' and 'Sum and Substance', Polygonatum odoratum var. pluriflorum 'Variegatum' and Polystichum polyblepharum.

Culture Notes
This magnolia is easy to grow. It flowers best when planted in full sun to light or open shade. It will thrive in a rich moist to well-drained soil, but will tolerate sand and clay if the drainage is adequate. Plant in an area that is protected from strong winds to help the flowers last their longest and keep the young foliage from being damaged. Regular summer water will allow the best flowering and healthiest growth, but well established plants can tolerate occasional watering during dry weather. Magnolias have fleshy roots that can easily be damaged so limit extensive gardening under established trees. Little pruning is required other than removing dead and broken limbs or poorly formed limbs. Pruning is best done after flowering.
