Well, one can dream C. flexuosa 'China Blue' and C. elata, two beautiful blue-flowered Chinese species, have been dependably perennial here for 8-9 years so far, so I hold out hope there are others that'll be growable.C. elata is a terrific species, does not go dormant later in summer like flexuosa does but stays in good green growth, with a long summer season of beautiful blue flowers that uniquely smell of coconut perfume.
McMark, are you growing "true" C. elata, or the C. omeiana that was for a long time being passed around by the name elata?See Ian's Bulb Log on the subject of these two Corydalis, with pix:http://www.srgc.org.uk/logs/logdir/2009Jun241245845561BULB_LOG__2509.pdf
An aside to all readers: Even if you are in possession of the Lidén and Zetterlund "Corydalis" book - ISBN 0-900048-66-2, published in 1997 by AGS Publications Ltd., I would recommend the book mentioned above by Mark Tebbit , Magnus Lidén and Henrik Zetterlund "Bleeding Hearts, Corydalis and their relatives" ISBN-13 978-0-88192-882-2, published in 2008 by the Timber Press. At the very least it is a great supplement to the first book and I would contend it is more than that
Errrrr.... mmmmm.... the omieana is scented, too, as are an awful lot of the corydalis of various sections that we grow
Of course, but the author specifically calls out the unique coconut scent of elata. Although, I don't think scent can be used diagnostically for species identification, although interesting to take note of such features.

Although, I don't think scent can be used diagnostically for species identification, although interesting to take note of such features.I disagree. Flowers are not like they are to be attractive for plant enthusiasts but to attract pollinators. Scent production is energy consuming and scent can be specifically targeted at a certain pollinator. Many taxonomists consider different pollinators (and therefore different pollination syndromes) a clear sign of a different species.
Granted, smell is a difficult characteristic to use in a key but that doesn't mean it is not a important diagnostic tool for taxonomy. I am not a Corydalis specialist but If I read all these characteristics I can't really be convinced omeiana and elata are different. 2 species are only truly different if there is a stable character or character set that distinguishes them. If such a character can not be found it would be unwise to keep them separate. The difference between 10 or 20 flowers to me does not seem to be such a character.
