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.

Clarkia romanzovii A.Nelson & J.F.Macbr.

Horticultural & Botanical History

‘Native of the North-west Coast of America, where it was observed by Dr. Chamisso, the naturalist of the late expedition of discovery sent from Russia, under the command of Lieutenant Kotzebue.  The species is named in compliment to Count Romanzow, the Minister of the Russian Marine.’  [BR f.562/1821].  The plant figured in Curtis’s Botanical Magazine as Oenothera tenella appears to be O. romanzovii Ledeb.  ‘Mr. Don, to whom we are indebted for pointing out to us that our plant was the tenella of Ruiz and Pavon, considers it to be the same species which has gone under the name of Oenothera Romanzovii; but if so, the former name has the right of priority, as well as being more appropriate.’  [BM t.2424/1823].  This may also be the plant described by Don under the name Oenothers tenella.  According to Don O. romanzovii was introduced to Britain in 1817.

History at Camden Park

Listed in the 1845, 1850 and 1857 catalogues [H168/1845].


According to some authors Clarkia romanzovii A.Nelson & J.F.Macbr. is identical to Oenothera tenella Cav. or a variety.  I have treated them as separate but related species here.  See also Clarkia tenella (Cav.) F.H. & M.E.Lewis.
