Unknown

A scentless white flower unknown to me. Since I bought it in a large flower shop with uncomfortably many customers, I just grabbed it and went faster than fast. Yes, I paid, of course. 
If anyone knows its name, I would love to hear it.

/It consists of a bunch of small white flowers on the top on a high heavy bare stem/.


Added: Simonslife knew the name.; Ornithogalum arabicum/Star of Betlehem. Thank you so much Simonslife.
