Corydalis 2017

Corydalis curviflora blue heron.

[Cfred72]

A Corydalis that deserves to be more cultivated. Who passes the frontiers of his native land. Which is offered for sale on the plant fairs this year at the castle of Berveelde in Lochristi in Belgium.
It's Corydalis 'Craigton Blue'

Corydalis 'Craigton Blue', a storming plant

Some pictures taken this morning.

1. Group, right to left, of Heavenly Blue and Craigton Blue near front and Spinners behind. Some more Craigton Blue and Spinners in the background. They have merged together. All do very well and easy to divide to produce more plantings.

2. Craigton Purple bought recently at the Perth show.

3. Vigorous plant bought as C. flexuosa - think from the society plant stall at an SRGC show. It is much bushier than my other corydalis - currently 30 inches tall. Have quite a few vigorous seedlings, but they have not yet flowered. Would appreciate advice on its identification.

I think C.  'Craigton Purple' will do well for you, Bob.  It makes quite a substantial plant with  good sized flower heads.  So far only MacPlants and Hartside have been given it to bulk up, so you're in the vanguard of growing it!

Hi
On 2nd June, I posted a picture of a very vigorous bushy blue Corydalis (now 80 cm tall) in my garden that was bought as C. flexuosa and asked if anyone could tell me anything about it.

It has seeded itself around. The seedlings in shady areas are bushy, while the self sown seedlings in open areas have very few basal leaves and quite a few long red stems, much thicker than anything that I have seen in the literature or the web and very different from my other corydalis. They have typical flowers that are purple in bud, but become bluer after they open. An example that has self seeded at the edge of the lawn is attached. (Not a site that I would have chosen, but have left it to see how it developed.) With the winds, a few of the stems have flopped to the ground, but then started growing vertically again. Have propped up stems in the picture with a couple of twigs.

The longest stem is 60 cm while others are 45 cm and still growing.

Grateful if anyone can give me any information on this.
Thanks Bob

Corydalis elata

Hi
I showed a scan of this corydalis (flexuosa??) on 2nd June. It is now past its best, but is still in flower and most of the leaves are still green while most of my others have died back or have yellowed leaves (although quite a few are showing fresh new green growth).

The plant is now 3ft high and there is a metal post and hoop deep within to ensure that it does not flop all over the place. Would really like to know its species and whether other people have such a vigorous blue corydalis. My Spinners and Craigton Blue both make reasonably sized plants and grow and flower well, but they are not nearly as vigorous as this one.

Here are couple of Corydalis  from last May.
In the first picture on the left there is C.marschalliana 'Crimea' and on the right C.bracteata 'Marina', very similar looking plants from a distance but there are small differences. Both plants are tall and grow well for me.
In the second picture is 'Crimea' closer, I love it.
In the third picture there is Corydalis integra.
