Hello All. I wrote a while ago about embarking on a painting project of 8 / 10 members of the genus tropaeolum. Can anyone suggest possible sources for seed of the following species...T.nubigenum; T. incisum; T.sessilifolium; T. hookerianum ssp. austropurpureum. As I am in Wales UK sources on the European side of the Atlantic would be preferable but any location would be appreciated. Tom Brown
