Corydalis are one of the seeds that grow best when sown as soon as they can be collected. This does not mean that older seed will not grow, but the germination is likey to be much more eratic.
Only buy your seeds from a reputable company, Simbad, or join one of the specialist Societies, eg the AGS, who only supply seed collected in the last year (it will be too late now for the 2009/10 members seed distribution).
Buy your seeds as soon as possible and sow them straight away in your usual medium. Goodf luck.

Thankyou Bulbaholic, is a reputable company I've bought from many times, so will order now and give them a go, once again thanks for your help :-)

many are really easy.
I agree with bob reputable company
sower beware seed varieties can take you over lol
a nice problem :))

I got seed from Chiltern Seeds.....very reliable...very prolific!!

Never had any seeds from Chiltern seeds Amblealice will have to give them a try, I ordered my corydalis seeds yesterday from Plantworld so fingers crossed, their seeds are usuallly good too, never had any problems :-)

Chiltern's have a wonderful selection and their catalogue is very descriptive...its difficult to put down. They have lots of unusual varieties too.
PS: I'm not on commission.......lol

Just had a look on Chilterns website Amblealice, they certainly have a huge selection, ordered a catalogue, you do realise this means I'll have to dig up more grass to make room for more plants, lol, all your fault :-)

He.he.....well...it will save you having to cut so much grass :-)))).....would love to hear what you order....

Well its taken a while, looking at the date I posted this question, but at last my first corydalis seedlings of 'Bronze Beauty' have started to emerge today only 4 so far but sure there'll be more, so exciting :-)

That is good news. Look forward to some pics :o-)
