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.

Horticultural & Botanical History

There is also a double form.  [PD].  ‘The place of this genus in a natural system does not seem to be finally determined.  By Professor de Jussieu it has been provisionally enrolled in his order of Gerania or Geranium-tribe.  Some species [of Oxalis] are to be found in each of the four quarters of the globe; but of rather more than a hundred that are already recorded, ninety are natives of the Cape of Good Hope.  The present is from thence, and was introduced by Mr. F. Masson in 1775. […] A greenhouse plant, cultivated in small pots filled with a mixture of peat-mould and hazel loam.  The drawing was taken this spring at Mr. Creswell’s conservatory in Battersea Square.’  [BR f.117/1816].
