planted a well grown 1 gallon pot last fall, it croaked over winter in spite of good snow cover. A friend had the same experience 2 winters ago here. So it can join the ever growing list of plants that hate the toxic climate of eastern washington

I originally planted my Blue Chiffon in a much too shady location. Finally transplanted to a mostly sunny site and it took off like a rocket. Flowers are truly blue, very beautiful.

The blue flowers are absolutely gorgeous! I planted mine last year. It bloomed profusely in the Summer despite being newly planted and young (about 3 feet tall). The flowers are sky-blue and look almost like tropical hibiscus blossoms. It bloomed all through July and then rebloomed in September.
