Plants in the Hortus
Many of the plants described here were listed in the catalogues of plants published by Sir William Macarthur in 1843, 1845, 1850 and 1857 and in an unpublished catalogue dated 1861. A large number of additional plants were identified from correspondence, gardening notebooks and other documents surviving in the archives. The Hortus attempts to describe all the plants grown in the gardens at Camden Park and those grown in horticultural enterprises such as orchards and vineyards and includes plants grown outside the gardens in the park-like environs of the Camden Park estate. The Hortus plants served a wide range of purposes in the 19th century household; as ornament, living fences, fibre, dyestuffs, medicines, food and drink from the garden, orchard and vineyard and many others.
