Fortune employed many different means to transport tea plants, seedlings, and other botanical discoveries, but he is most well known for his use of cases like small greenhouses called Wardian cases (as used by Nathaniel Bagshaw Ward) to keep the plants alive. With these cases Fortune introduced 20,000 tea plants and seedlings to the Darjeeling region of India. He also brought with him a group of trained Chinese tea workers to assist in the production of tea leaves. Except for a few plants which survived in Indian gardens, most of the Chinese tea plants Fortune introduced to India died. The special growing methods and knowledge that was brought over from China, however, may have been very helpful in the later success of the Indian tea industry.
