Allium red mohican flower size ?

Has anybody grown Allium red mohican ? I am thinking of buying some but would like to know how big the flower head is ? it hard to gauge off a picture but they look slightly larger than Sphaerocephalon .

 

@Perki if you don't get any info go to hydes bulbs and send them an email they are really helpful and the bulb quality is good too.
