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

Pentstemon laevigata was cultivated in Dr Fothergill’s garden at Upton, in 1776; but has probably been long lost to our gardens, till it was lately again introduced by Messrs. Fraser.  At least, we have usually seen the narrow-leaved variety of pubescens passing under the name of this in our nurseries.’  [BM t.1425/1811].
