Bloomfield Dainty is probably triploid

My new Bloomfield Dainty plant has just flowered for the first time. The pollen diameter (acetocarmine stained) is 36.1 microns and the standard deviation is 4.9.

This large standard deviation strongly suggests (to me) that the plant is a triploid.

It won’t set hips here. It seems I’ve tried the pollen with no success. If I remember correctly I put it on Playboy.
