  • The story of ‘Tai-Haku’ is provided by Wybe Kuitert (1999, p. 330).  Briefly, the plant was sent to England from Japan to a Mrs. Freeman in about 1900.  However, the tree in her garden was near death in 1923 when Collingwood Ingram, an authority on Japanese flowering cherries, noticed the large size and beauty of its few flowers.  He collected a few twigs of bud wood from which thousands of trees have since been propagated and distributed world-wide.  Apparently, this selection had been lost in Japan, and Ingram reintroduced it into that country in 1932.  It was named by a Japanese nobelman and politician, and a friend of Ingram, Nobusuke Takatsukasa, when Ingram showed him the tree in the spring of 1925.  He called the tree Tai-kaku, tai (great) and haku (white), a reference to the size and color of the flower.  A more detailed story of Collingwood Ingram (aka, 'Cherry' Ingram) and Japanese flowering cherries is available in a book written by the Japanese author, Naoko Abe.  The English version has been published under different titles, including:
