My vegetable patch now includes kailan (Chinese kale)

I was wondering if kailan, when harvested young would result it baby kailan. Sounds logical enough, right? There would be baby kailan and left to get bigger would become 'adult' kailan. Right? Mom insists that baby kailan is a different breed of kailan altogether. They'd of course be smaller, this its 'baby' name. But no, a young kailan is not the same as a baby kailan.

So I guess that I will be letting these babies grow for now and harvesting them later on as 'adult' kailans then. Haha!
