I received Bradley Bernard as a gift two years ago. It was small, so I put it in a holding bed the first season. I moved it to a permanent position last summer. It has not bloomed yet, but it did increase and bulk up well. To be fair, the holding bed position was quite shady. It is in a sunny spot now, so it should bloom this summer.
Update, May 2, 2018
Bradley Bernard is now greening up, and I counted at least seven fans.
