Welcome to Tom Brown and his interest in Tropaeolum. Wales is a pretty wet place to grow most of them! A good source of Tropaeolum seed is Chileflora. I also got Tropaeolum beuthii seed last fall from Kurt Vickery and it has germinated. T. azureum seed is often available in AGS and SRGC seed exchanges -- that is where I got it. I had Tropaeolum incisum in my former garden, but when I tried to dig up the tuber, it had plunged so deep and wandered so far I could not find it. Too bad, it is very beautiful! However, it can take several years to raise a flowering plant from seed, or even to get the erratic germination typical of Tropaeolum. Perhaps Tom should plan his painting project for a longer term?
