Searching the web for Tropaeolum azureum I found a link to your forum. Some years ago I saw a picture of this plant in a german garden magazine, I bought some seeds and tried to germinate them but without success. If there is someone in this forum growing T.a. I would very much apreciate his information.
I am growing Tropaeolum tricolor, which blooms now. I could exchange bulbs of this plant when dormant in summer for bulbs of Tropaeolum azureum.
looking forward for any help
