Destined to See has been here in my zone 4 garden since 2006, first bloomed in '07. The original 2 fans have multiplied extremely well and has been divided into 3 med to large clumps....which need dividing again.
The area it is planted in has gained more shade over the years and it still continues to perform the same way it did in more sun. Here DTS has always had top branching, a simple "Y" and about 8 -12 buds., blooms for 3 to 4 weeks, and frequently polys. A short plant for the front of the bed, blooms have clean color, crisp near white with a blue violet eye, more blue some days, others more violet. Can't think of any time I've seen it have a problem opening even with our cool night temps that can be in the low 50's during peak bloom. One of my favorites and a favorite of many visitors.
Bloom image from last year, and an early season shot of one of the three clumps also from last year.
