What a great choice Paha Sapa Thundercloud turned out to be! Hybridized in 2003 by Gary Schaben in Minnesota, this dormant tetraploid has been a very hardy grower for me. In fact, it is so vigorous that it grows 37" tall -- a whopping 10" taller than its registered height! Paha Sapa gets no special attention or fertilizer, either.
Blooms are 5" in size (21-25 bud count). The bitone blooms are beautiful, rich in color, consistent, and have a heavy, waxy substance. They always look perfect whether it's a hot sunny day, if there's high winds, or torrential rain. This plant is tough! Also note the neat pink-ish purple anthers in the bloom. In my 2019 garden, Paha Sapa Thundercloud bloomed from July 22 through September 14. In 2020 bloom started on July 17.
