Grow it too. Think it was a new plant 3 or 4 years ago. Wonderful scent.
I try to regularly deadhead but it flowers so profusely...as most dianthus do.....so I often hack all,the stems back.
I think it is important to have a good healthy air flow around the plant so removing stems to the base is important.
That,"whitish brown" happycottontail , is mildew I think caused by your plant getting too dry so a good watering now and then should help. Cut off all affected parts to leave nice clean foliage
