Re Tropaeolum hookerianum, it grows in areas that experience slight frost. I consider the native climate much like that of the middle foothills of the Sierra Nevada (California) east of say Fresno. One piece of advice: if you give it something to climb on, use a twiggy branch, not metal. I had some tropaeolums die after being frozen on metal supports. I saw a photo of T. brachyceras flowering as a pretty dome and wrote to the grower in England to find out how she did it. She told me she had made a dome of chicken wire over the top of the pot and trained the stems round and round on it. This yellow species can become very large with time here.
