I first saw this double petaled Impatiens in soft pink, red and white at Fraser's Hill, Malaysia when we visited for the weekend. Fraser's Hill has a day temperature of about 25 degrees C. So the cooler temperatures were just suitable for this plant to grow. We got some cuttings and mom planted them in her garden. They survived for a few months but when the temperatures got really hot to about 33 - 34 degrees C, they succumbed to the heat.
I got these peach ones from a nursery nearby and asked for other colours but they only had these. They are doing well now and I hope they continue to thrive before the weather gets too hot. I am hoping that because they were propagated here in Singapore, it would be more adapted to the hot temperatures.
