Colin Mills, compiler of the Hortus Camdenensis, died in late November 2012 after a short illness. As he always considered the Hortus his legacy, it is his family's intention to keep the site running in perpetuity. It will not, however, be updated in the near future.

A division of the Camden Park catalogues that is not clearly defined. In broad terms it includes all plants with woody stems except conifers and fruit trees and shrubs.

Araujia sericifera Brot.

An unidentified Physianthus or Arauja species, twining or climbing perennials.  Physianthus is now generally included with Araujia and Physianthus tricolor may be another Araujia species.  Possibly Arauja  sericifera Brot.    which is described and illustrated here, although it is difficult to see how the specific epithet tricolor applies to this plant.

Arbutus andrachne L.

Spreading, sometimes shrubby tree with smooth, peeling, red-brown bark and white flowers in erect panicles in spring, followed by spherical, warty, orange-red fruit, which ripen in the autumn of the following year.  To 6m by 6m.  [RHSE, Hortus, Hilliers’].

Arbutus canariensis Duham.

Half hardy shrub or small tree with oblong to lance-shaped leaves, to 12cm long, and erect terminal panicles of pale green, often pink-tinted flowers, about 1cm long, in summer, followed by warty, roundish fruit.  To 9m.  [RHSD, Hortus].
