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.

Oenothera bifrons D.Don

A nearly erect annual or short-lived perennial with purple-tinged stems, alternate, smooth, broadly lance-shaped leaves, and solitary, axillary, bright canary yellow flowers.  [BM t.3764/1839].

Horticultural & Botanical History

‘Another and very distinct species of Evening Primrose, discovered by the late Mr. Drummond in Texas, and introduced to our gardens, is that here figured.  It may be at once known by its semiamplexicaul leaves, of which the upper, gradually passing into bracteas, are remarkably broad and exactly cordate.  It is quite hardy, and a very free flowerer, each panicle, and, indeed, branch of a panicle, hearing a great number of buds, which open in succession.  With us, in the Glasgow Botanic Garden, it has flowered in August and September, and bids fair to continue blossoming till the frosts destroy the plant.’  [BM t.3764/1839].  Introduced to Britain in 1835.  [JD].

History at Camden Park

Listed in the 1845, 1850 and 1857 catalogues [H.161/1845].


Another possibility is Oenothera bifrons Lindl. which is probably synonymous with Godetia bifrons Hort. which see.
