I planted some stephanotis (a.k.a Madagascar jasmine) seeds last January. I fear that they may be growing more than they should. They are under lights and I water them regularly. One of them is 17" tall. It is growing at about 1" a week. That seems very nice. But I have read that if they do not get a winter dormant period, and grow all winter, they will not flower next spring - presumably because their natural cycle has been disrupted. Any comments?
