Looking East - botanical tales from China

Last year marked the 17th year of the partnership between Bristol and Guangzhou (formerly Canton) in southern China and at a public talk later this month, the curator of the University of Bristol Botanic Garden will talk about his recent trip to China.

The talk by Nick Wray, Curator of the Botanic Garden will take place on Thursday 21 February at 7.30 pm.  Nick will speak about his visit to Guangzhou city and the Yingde Mountains to meet tea growers and see the Yingde Karst stone landscape and its quarries.

Located on the Pearl River about 120 kilometres north west of Hong Kong and 145 kilometres North of Macau, Guangzhou has a history spanning 2,200 years and was a major terminus for the maritime silk road and continues to serve as a major port and transportation hub today as well as being one of China's largest cities.

Nick Wray, talking about the visit, said: "A major aim of the trip was to make a link between the University's Botanic Garden and the South China Botanical Garden. Other objectives included sourcing new lotus Nelumbo nucifera cultivars and different species of tumeric and other members of the ginger family; investigating their medicinal herb collection to identify possible species for Bristol and visiting classical gardens of Guangdong including Qinghui Yu Jin Shan Fang and Liang Yuan gardens as models for the culture gardens at Bristol."

In the lecture Nick will speak about his travels with Tony Harrison, co-ordinator of the Garden's Traditional Chinese Herb Garden and former Vice President of the Register of Chinese Herbal Medicine and some of the people they met. They visited the home of Yingde tea which is famous throughout China. The tea character is Oolong and the most profitable cultivar is called 1959, a blend developed and named in honour of our Queen Elizabeth's state visit to China in that year. This high-profile blend which is sold in China commands a high price of £80 per kilo retail and £40 per kilo wholesale.

The trend in China is for more tea growers to grow in a sustainable way. Pesticide use became mainstream about 20 years ago in a drive to increase food production. In sustainable systems cows are frequently being introduced to tea plantations (they eat weeds, but not the tea as its tastes bitter) and supply extra nutrients. Trees can grow at higher density and a mixture of tree species is cultivated to attract different bird species.

The lecture 'Botanical tales from China' by Nick Wray, will take place on Thursday 21 February at 7.30 pm in The Frank Theatre, Wills Physics Laboratory, Tyndall Avenue, Bristol BS8 ITL
