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.

Phlox paniculata L. var. grandis

Fully hardy, erect, herbaceous perennial with lance-shaped, toothed leaves, to 13cm long, and panicle-like cymes of salverform, fragrant flowers, to 2.5cm across, in shades of white, pink, lilac, orange or red, often with a contrasting eye, from summer to autumn.  To 1.2m. The name grandis suggests a tall-growing or large-flowered form.  I have found no specific reference to the variety.  [RHSE, Hortus].

Horticultural & Botanical History

There are many garden cultivars, and horticultural forms are often known as Phlox decussata.  Introduced to Britain in 1732.  [PD].  ‘Native of Georgia and South-Carolina.  Rather more tender than many other species.  Flowers in August and September.  Introduced by the late Mr. Lyons, in 1812 [as Phlox acuminata].  Communicated by Mr. William Kemp, of Clapton, in September 1815.’  [BM t.1880/1817].

History at Camden Park

Listed in the 1857 catalogue [T.750/1857] but certainly grown by 1853 as plants were sent to the Sydney Botanic Garden in that year.  [RBGS AB].
