For the last three years, this iris has rebloomed in September and October - as has its sister 'Easy Smile' - both registered in December, and working on building up enough for introduction.
This year 'Cricket Song' has decided to send up three additional repeat stalks. The main flush was mostly in early May, as you can see the fat pods from those blooms in the foreground of the first picture.
The only other bearded in bloom now is Iris ruskyii which is almost always my last.
This type of repeat bloom is more typical of its pollen parent 'Clown Pants' which never has bloomed in the fall, but every other year has some repeat stalks well after the main flush.
