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.

Penstemon angustifolius Nutt. ex Pursh

Herbaceous perennial with linear to lance-shaped leaves and clusters of white, blue, lilac to pink flowers.  To 30cm.  [RHSD, Hortus].  The flowers in the accompanying illustration from Loddiges’ Botanical Cabinet are bright red but seem to be otherwise accurately depicted.
