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.

Lobelia tenuior R.Br.

Half-hardy perennial with deeply toothed, obovate leaves and deep blue flowers with a white eye.  To 30cm.  [RHSD, Hortus].

Horticultural & Botanical History

‘A species of great beauty, from the very brilliant colour of the flowers.  The Glasgow Botanic Garden owes the possession of the plant to Mr. Lowe of the Clapton Nursery.  The blossoms, we allow, are not so large as those represented in the Botanical Register; but they are equally large with those of the specimens sent to us from Edinburgh, and with those figured by Labillardiere from native specimens.  The species inhabits the southern extremity of New Holland and of Van Diemens Land.  With us, in the greenhouse, it flowers in the autumnal months.’  [BM t.3784/1840 as L. heterophylla].  Introduced to Britain in 1838.  [JD].

History at Camden Park

Seed order to Hurst and McMullen, Seedsmen and Florists of London, on 8th April 1846.  [MP A2933-1, p.132].
