I received, if memory is correct a 3 fan gift of Regal Finale back in 2015. It was potted and remained that way until early fall of this year, when it was finally added to a border bed.
Lovely purple bloom but my stats have it performing less than what is listed on the site. I believe it to be due to its being potted and somewhat neglected. Although, since being planted, it's increase has been steady and I counted 10 fans emerging from the soil this morning.
I believe 2017 will have its performance up to par, and look forward to seeing it bloom again.
