Outstanding Qualities Magnolia x kewensis is a cross between M. kobus and M. salicifolia that has been recorded as occurring where the range of both species intersect in their native Japan and in cultivation. ‘Wada‘s Memory‘ was selected seed sent from Japan by K. Wada and Brian Mulligan of the Washington Park Arboretum named a superior clone for his friend and registered the name in 1959. This widely popular magnolia has white flowers 7 inches in diameter, produced in profusion in March and early April. Emerging leaves are bronze and fade to green as they mature. ‘Wada‘s Memory‘ has a strongly pyramidal form into maturity making it stand out against more rounded trees in the landscape. This lovely magnolia with local provenance is fast growing and turns a gold in the autumn. See magnolia denudata for companion plantings.
Culture Full sun and average moisture suit magnolias best and humus rich soils. They will not tolerate saturated or poor soils. Garden gently under magnolias, for they have fleshy roots that can easily be damaged. The best approach for companions plants is to tuck in natural spreaders and let them flourish untouched.
Growing Habit ‘Wada‘s Memory‘ is neatly pyramidal to 15 by 10 feet in ten years and 30 feet tall by 20 feet wide at maturity.
Hardiness USDA zones 5 to 8
