2023 update…STP had a great year, blooming from June 28 to July 27, with at least 22 blooms. It had a short rebloom period, September 9-13 with 3 more blooms before bunnies chewed off the scape. It even managed to more than double itself, growing from 3 scapes in April to 7 scapes by October. It seems to be quite hardy here in zone 6b.
