Bulbous and Tuberous Rooted Plants
A division of the Camden Park catalogues that is not clearly defined. Some of the more important families of the Hortus are included here, Amaryllidaceae, Iridaceae and Liliaceae. It also contains a wide assortment of other plants with a modified stem or root that acts as a storage organ. Such plants are usually deciduous and have a distinct dormancy period. Shrubs and trees are not included, but there is some overlap with herbaceous plants.
