I did notice 'Barn Dance' is significantly shorter and more compact than either parent, and especially Prairie Princess. The internode spacing is roughly the same as each parent, so there isnt much evidence than any semi-dwarfing from Fashion came through. In other words, a reduction in size is possible from the reduction of ploidy and recombination of triploidy factors from one parent or the other.
The ovoid, pointed buds open to double (20-25petals), shallow cupped, 3-4 inch blooms. The abundant, leathery, medium-sized foliage is pale green, aging to dark green. The plants are winter hardy except in the coldest regions.
