The third important ancestor originated near the cold-winter tip of South America, at 53 degrees to 55 degrees S. That predecessor, F. magellanica, is also the hardiest garden fuchsia that's widely grown today.
Fuchsias dislike consistently high temperatures.
That makes them difficult to grow wherever sweet corn flourishes, because sweet corn begs for the same hot nights that make fuchsias collapse. During the growing season, fuchsias prefer temperatures in the 60o to 75oF range. Also, fuchsias need light shade, not too much direct sun, and not much wind. They respond happily to generous irrigation from rain or from a garden sprinkler, but very high humidity does not benefit them. Their soil must be permeable and rich in humus, with a pH between 6 and 7.
