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.

Achimenes ‘Sir Trecherne Thomas’

‘Sir Trecherne Thomas’ is a crimson-flowered hybrid of Achimenes ‘Boekmanni’ x Achimenes grandiflora bred by Louis van Houtte.  Achimenes ‘Boekmanni’ is itself a cross between A. longiflora and A. grandiflora.  [GRA p.37].

Horticultural & Botanical History

The Floricultural Cabinet described the flowers of ‘Sir Trehorn Thomas’ as very large, of a brilliant carmine-red colour, and exceedingly showy.  ‘Sir Trecherne Thomas’ was listed by Edward George Henderson and Son, St Johns Wood, in The Gardeners' Chronicle: ‘A large rich coloured flower, fimbriated (some will say it is carmine, others a crimson or rosy purple; we do not, however, know ourselves what colour to call it, but it is the best Achimenes we possess); habit excellent, robust, and dwarf, a free, abundant flowerer, and one that will supersede a dozen other varieties that have hitherto been cultivated.’  [FC p.198/1853, Gard. Chron. 1854].  ‘Sir Trecherne Thomas’ is still available and suggested as a good variety for a small collection.  [].
