Yoyogi Koen Onion Family

One the way to the Okinawa Matsuri 2017 in Yoyogi Park, I spotted these unusual purple flowers and stopped to take a photo. Believe it or not, these flowers are in the onion family! Not sure if I got the exact type, but based on a quick google search they look like Allium 'Globus'.
