My Corydalis had nicely started to come into flower just before the 'Beast from the East' dropped a load of snow on them, and just as they had recovered from that a further dump of snow hit them last weekend whilst we were away in The Homeland. So these are not really at their best.

David, I wouldn't be so critical - they just look nice. Mine are only showing noses.
-
I´d rather say Your Coydalis put up a big show, David!
This isn´t something one would say of Corydalis pumila, which is in flower right now here in Sweden. The flowering lasts only for 2-3 days. Maybe that´s one of the reasons why the Swedish colloquial name means Good-For-Nothing-Corydalis. It cannot be mistaken due to it´s typical bracts.
-
Whereas Corydalis pumila is rare in Sweden, Corydalis cava is one of the two usually found. Here it grows together with hepatica, unfortunately not so lovely blue as Your C. cava.
-
The other Corydalis more often found in Sweden is Corydalis intermedia - the lower bracts are splitted, the upper ones not.
-
Back home in Germany, the Corydalis will be withered by now. This year was C. solida ´Blue Giant´one of my favourites.
-
In Germany, more and more pinkish Corydalis malkensis are reported, supposed to be hybrids with C. solida. One I got from a friend, this one popped up in my garden last year.

I'd like to offer fresh Corydalis nobilis seeds to anyone who wish to have it. It is in full bloom now but as temperatures are reaching +30 C, so it will be ready to shed seeds very soon. I will send it in small plastic bags with some soil added to retain moisture, in envelope, as a letter. I have practiced this with one of the forumists and it worked very well. I already have one order this year.
I do not really expect anything for exchange, so do not hesitate and order. But I am happily collecting genus corydalis and I have in profusion: Pseudofumaria lutea and ochroleuca and Corydalis: solida in pink, red and ordinary purple shades, malkensis, cava (white and purple), cheilanthifolia. All others are either struggling to survive or not producing seeds for whatever reason (like C. bushii, C. flexuosa, C. ellipticarpa) - and are prone to die one summer or winter when the weather is too aggressive. So if you have surplus of anything that I don't have - I will be happy. My garden conditions may be good enough for some easier steppelanders, too.
Just a word of warning. C. nobilis is a big plant, not good for a rock garden. It is good for more abandoned places, in a forest or under shrubs. It will out compete small spring plants except those very early ones with short growing season, like C. solida or Galanthus nivalis. I find it very drought resistant and shade tolerant. It's doing reasonably well in bright spots, too. I do not have experience with it in hot and dry spots. It is probably more decorative in cold/cool climates - my plants do not look as good as those from Scandinavia. It does self seed abundantly and fast in shedding seeds. It is not a self-cleaning plant like C. slide - it dies slowly at the end of spring. It is fairly difficult to transplant as the perennial underground portion resembles branching carrot. It is long-lived in my garden.
If you want it, just send a message to me, with address.

A couple of blue Corydalis from the garden today:-
Corydalis 'Spinners' ------- a bit of a scrambler.

I see the bees have been chewing their way into the flowers to pinch the nectar!

... and not one of them buzzed me to see if it was OK ::)

Corydalis 'Craigton Blue'

David, is 'Spinners' earlier for you than other blue corydalis like 'Craigton Blue'?
-

It's earlier than some Leena but later than others. In my garden 'Blue Heron' is always first and regardless of the bad weather this year was in flower in March. It's taking a break at the moment but I expect it to have another flush of flowers in late-Summer, early-Autumn. 'Blue Dragon is usually next, followed by 'Spinners'. Then 'Wildside Blue' followed by 'Craigton Blue' and elata should be in flower later this week. I also have 'Hale Cat' which I nearly lost but managed to save a small cutting but it never seems to grow.
-
Thank you David! :) I planted 'Spinners' last year and now noticed that it was the first of my blue Corydalis to flower already in May (but May was very hot this year here), it is good to know that is how it should be, and so most likely my 'Spinners' is the right plant. Then there are other blue flexuosa type Corydalis which I have all gotten as 'Craigton Blue', but they flower earlier than the plant I got from Maggi, so I suspect they are something else. it seems here all blue Corydalis are named 'Craigton Blue', it is the most famous name.
Also here C.elata flowers the latest, usually in July.

Corydalis were a little late here this year.
Corydalis fumariifolia -a late-flowering form which didn’t cope well with the hot May that we had.

Corydalis cashmeriana -was in flower earlier this month and may flower again in August if the Summer is not too hot.

Corydalis sp. -This is a dwarf scree species that I got from a Chinese source. I gave some to Cyril then lost my parent plant; fortunately Cyril managed to propagate it so I now have another opportunity to kill it!
I find that it gets leggy under glass and is a martyr to aphids. I am now growing it hard outside where it is creeping out of a crevice into full sun.

I have had trouble growing blue bulbous Corydalis (C.turtschaninovii-type), they slowly decline, or at best stay the same. Maybe I haven't found just the right place and soil for them earlier, because now this C.turtschaninovii looks fine, and last spring was it's second spring here.
Corydalis buschii does very well, it is even a little weed-like so that when I have moved it, it grows back from the tiniest root piece.
