All stalks produced a single flower from last-years multi-flower seeds. Back where we started from on height, hoping for few centimeters improvement next year -- HOWEVER the tallest 99" stalk collapsed from the weight of the flowers and the seeds were not muture. Not sure if they will sprout next year, or if I'll have to resort to the second tallest at 94". Since the experiment is to select for height and not other factors like sturdiness, next year I will stake the tallest stalks.
