Hi. I have joined pbs to find info. and planting materials for the Genus tropaeolum. I live in Wales UK, you can see photos. of our countryside at http://www.yfelin.plus.com/ . I have selected tropaeolum as a subject for a series of botanical illustrations to be produced over the next year to eighteen months. I have recently acquired the following species.... T. brachyceras; T. ciliatum; T. polyphylum; T. tuberosum Ken Aslet; T. piliphera. I would like to add a few others to the list such as T.azureum and T. incisum. What I am looking for is a variety of species that would show something of the variety of form, habit and colour within the genus in a series of 8 or 10 paintings. Tom
