Sue, I'm so disappointed for you that you don't get rebloom. Ever since I rescued mine from an overgrown, crowded part of my garden and put it on a sunny border, I've been getting regular rebloom. You must be oh-so close.
In 2017, BE Stella bloomed for me from Jun 14 to July 22, and then again from Aug 13 to Sept 30. I like big, awesome flowers, and I like art-like blooms with intricate faces, but I still appreciate a simple, hard working plant that provides me more days of bloom than most other plants. BE Stella is one of those for me.
