Tropicals & Tender Perennials: New Guinea Impatiens, 0 by tropicbreeze

I saw lots of impatiens while trekking in Papua New Guinea recently. What I noticed was that they grew in the mountains in the wet jungles. There they don't experience high temperatures, nor do the temperatures drop very low. This is what would make them more difficult to grow in low land areas where you get greater temperature fluctuations. That would also be compounded if there is also low humidity.
