Information about Alliums

This question was asked by

I notice that the description for some alliums says
e.g. Height 90 – 120cm
But then further down it says size for this price 22cm
I don’t understand what that means. I wonder if you could explain, please?
Will the alliums grow to 90 – 120cm or just 22cm?

The height is how tall the flower will get and the ‘Size for this price’ is the bulb size.
