Obtained the seeds from Select Seeds and planted in peat pellets ahead of time.

Planted in two part-sun locations: one with poorer soil than the other. The specimens in the poor-soil location grew to about 18 inches, and two have bloomed (pink and light pink photos).

The specimens in the better soil are taller and wider (~36 inches) and only one has bloomed (white photo).

They didn't bloom until extremely late in the seasonSeptember and Octoberand most of their fellows have buds but probably won't bloom before first frost.
