I don't know this plant but I find upon Googling that it is Allium tuberosum (Garlic Chives),rather than Allium schoenoprasum (True chives), so I imagine it would taste accordingly.

Thanks for the info, Flora.

Then if it is Garlic Chives they will have no problem re-producing both by division and by dropping seeds. They even have sprouted in my lawn with no problems.
