Dormancy in Ornithogalums

I have a pot full of Ornithogalum longibracteatum bulbs that need to be divided.  It is so crowded with bulbs that I am not sure how much soil is left.  None is visible.  I assume this genus has a dormancy period where it stops growing but does not die back.  If so, what time of year does this happen.  long day? short day?  Please correct me if I am misinterpreting what I am seeing.  When it is dormant I will divide and send bulbs and bulblets to the Exchange.  Or at least I will when the danger of freezing in transit has passed.
