Analysis of plant remains of 73 taxa obtained from the graveyard of the Haihun Marquis (circa 59 bc) at Nanchang, China, is presented. Chronology was confirmed by direct AMS radiocarbon dating of both a seed and wood, while plant seeds were collected by wet sieving. Detailed composition of the samples suggests that the fundamental landscape of the graveyard was composed of Platycladus orientalis, a symbol of solemnity and compatible with the high status of the tomb owner Liu He. Furthermore, seeds of Sapium sebiferum, Castanopsis sclerophylla and Lauraceae, among other high-status plants were also discovered and thus could be included in the landscaping of the graveyard of the Haihun Marquis. In addition, plants like Poaceae, Santalaceae, Cyperaceae and Broussonetia sp., among others, represented a considerable share of the graveyard growth. Fruit stones of Amygdalus persica, Armeniaca mume and Cerasus pseudocerasus discovered in the well may have been included as fruit trees, but grew outside the graveyard. In the main tomb (M1), remains of five plant were discovered, i.e. Oryza sativa (rice), Cannabis sativa (hemp), Setaria italica (foxtail millet) and Cucumis melo (sweet melon), as well as Armeniaca mume (Japanese apricot) and had been placed in the tomb for further use as cereals and fruit by the deceased in the world beyond, thus also demonstrating diversified plant use in the Western Han Dynasty.
