We can't really trust growers. They often label their plants incorrectly. The Internet's full of growers who still call their plants Salvia nemorosa or Verbena x hybrida even though those names are no longer accepted.
The Pazzaz series does have many varieties with blooms that aren't yellow, so that would exclude them from the P. oleracea species, right?
I'll change the species name in the Pazzaz entries to umbraticola.
Please don't hesitate to make other requests, Becky.
