Pink-flowered thornless blackberry
I got three thornless blackberry plants as part of a trade here last year, which I was told were probably Apache or Arapaho. I have a row of Apache, but the growth habit and flower color of these is different. Apache being fairly compact and upright with white flowers, and these new ones made 7' horizontal canes (which I tied up to a post) and have large bright pink flowers which fade to pale pink.
From the plant patent info, Arapaho has white flowers.
Can anyone offer a guess as to what variety this might be? Black Satin is one that's supposed to have pink flowers- do any others?
