Do you have a courtyard or some pot plants on your balcony? Do you know where these plants come from?
Are they Chinese plants or do they come from another country?
When you last visited a public garden, did you look at the individual plants
there? Were there any plants from other countries?
How do you think plants have traveled from one country to another?

The Wardian case
Robert Fortune (1812-1880)
represented the Horticultural Society of London (now the Royal Horticultural Society) as a collector in China shortly after the Treaty of Nanjing had brought the Opium War to a close. Through his use of the Wardian case, Fortune was able to introduce many of the best-known Chinese garden plants into cultivation in Europe and North America.
