Emmenopterys henryi is a species of flowering plant in the family Rubiaceae. It is found in the temperate parts of central and southern China and in Vietnam. It is a deciduous tree with opposite leaves and can attain heights of 45 m and grow to be 1000 years old.[citation needed] The epithet is named after the Irish botanist and sinologist Augustine Henry. The trees may not flower until they are 30–100 years old, and flowering seems to be triggered by a long hot summer. Many inflorescences are accompanied by a large white bract.[1]
Emmenopterys henryi in Europe
The first introduction to Europe was 1907 to England by Ernest Wilson.[2][3] They are noted for their rare flowering. The first time that Emmenopterys henryi flowered in mainland Europe was 1971 in the arboretum of Villa Taranto on Lago Maggiore, Italy.[2][3] At Borde Hill Garden, West Sussex, UK there are 2 specimens with the older planted in 1928 from seed collected by George Forrest which flowered in 2011,2012, 2016 and 2018; the smaller specimen has flowered 3 times and was planted in 1976 from micropropagation of the Kew specimen that was in poor condition due to the drought.[4][5] A specimen in Cambridge flowered in 2012, after 30 years, only the fifth flowering in the UK.[6] In 2013, a tree flowered for the fourth time in the Arboretum Kalmthout in Belgium. This was unexpected, since the flowers only appeared in September, which is quite late.[7] After the 2018 heatwave in the UK, a 100 year old specimen in Roath Park, Cardiff flowered for the first time ever.[8]
