I must admit I love the doubles, partly because I grow them as houseplants and they are ideal, pretty, easy and growing so busily as to always have something new to see. I enjoy growing them from seed too, and seeing what I get! I like the New Guinea hybrids then also, in fact, let's face it, I love them all! What is the butterfly variety, Debbie?

Hmmm
I really dont grow many of the common bedding plants. Not because I dont like them, I do, its just that I need room for my species. If I had to pic a hybrid, I would say the NG varigated hybrids. They look mighty pretty and even when not in flower they still add color.

The butterfly series is just the repackaging of the variety with a colored center to the flower.
There is a new Butterfly series that is totally different. This new one is a cross of walleriana and pseudoviola. There are about 5 different colors and seem to be heat tolerant.
If I had to pick a speices I would say Impatiens arguta this one does well in the heat and is fairly cold hardy down to 1F I have read. It seems to stop flowering when its in the 100s but if given more shade and planted in the ground it should flower more.
