Thanks to all those who responded to my introductory message re my interest in the genus tropaeolum for the purpose of a botanical painting project. I have tubers of..T.brachyceras, ciliatum, polyphylum, tuberosum (Ken Aslet) & piliphera . I would be grateful for any advice regards their planting....soil conditions; location; watering; etc.? Would planting in pots be recommended/OK and if so what sizes? Tom Brown Wales, UK
