About

Magnolia denudata

Magnolia denudata is one of the most beloved of all magnolias. Called "Yulan" or "Jade Lily" by the Chinese, the exquisite lily shape of the white blossoms (some with a tinge of pink at the base of the tepals), has the longest history of magnolia cultivation going back to the Tang Dynasty – 618 AD. Its beauty was celebrated on ancient Chinese embroideries, scrolls and porcelains in scenes of the countryside. Its elegant flowers made it "a gift worthy of an emperor." The tepals (petals and sepals that aren't differentiated) are also known as a delicacy, dipped in flour and lightly fried. Today, very old gnarled specimens can be found in Chinese temples and other public places throughout China.

Magnolia denudata was the first magnolia to be introduced from Asia to the western world when it was brought to England in 1780. It is one of the parents of many cultivars, the more famous including Magnolia x soulangeana, a cross between M. denudata and M. liliflora; and Magnolia x veitchii, a cross between M. denudata and M. campbellii.

Many Asiatic magnolias are precocious bloomers (flowers appear before the leaves), creating a very dramatic scene in the late winter early spring. We have six mature specimens scattered around the Garden, each seeming more graceful and elegant in appearance than the other. One not to be missed is the largest M. denudata standing about 30' tall by 40' wide in the Southeast Asian Cloud Forest garden. This is the only specimen in the collection that shows the pink blush at the base of the outside of the tepals, a natural variation found in the wild in China.
