A nice guy sent me a cutting of impatiens hians. Unfortunately, it doesn t want to make flowers.

The cutting has roots, it is in a good health, it grows a lot. Other impatiens I have are flowering a lot...

What can I do to have flowers? Why is impatiens hians more difficult than others ? Has somebody an idea in order me to have flowers?????

Thanks for your answer..
