I bought Little Ana Rosa 2 years ago. It was a very nice sized clump when I got it and it bloomed and bloomed and bloomed. Last year again, tons of blooms. This year is an off year for it. I have had only 2 scapes.
It is definitely a little mini that catches your attention. I am going to move her to my mini beds in a few weeks. She is kind of lost behind the Stella's in her current location. (Plus she is planted right near my bluebird house and it has been occupied all summer so I haven't really been able to get close enough to really enjoy them without getting dive bombed by Mr. Bluebird!!)
I did see some bud building tendency in 2016. My first bloom this year was July 10, last year it was July 17. So more of a early mid season for my area.
