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.

Sinningia speciosa ‘Grandis’

A cultivar of Sinningia speciosa (Lodd.) Hiern. It is not listed under this name in the main Gesneriad Register – Sinningia, or in the Appendix.  I have found no detailed description for this plant but the description in the Journal D'Horticulture Pratique de La Belgique  implies that it is a slipper gloxinia with white flowers with a marked crimson stripe at the base.

Horticultural & Botanical History

Listed in the Journal D'Horticulture Pratique de La Belgique by Henri Galeotti with a partial description: ‘Gloxinia grandis, magnificent hybrid with flowers of the same colour as Gloxinia Marie van Houtte, but much bigger.’  ‘Marie van Houtte’ is figured in Flore des Serres [FS pl.610/1850] and that is the image used here.

History at Camden Park

First recorded in a handwritten entry in a copy of the 1850 catalogue held at the Mitchell Library and inscribed on the front Wm. Macarthur, 23rd Dec. 1854.  [ML635.9m].  Certainly grown in the gardens at this time.
