bok choy flowers?**newbie alert**
This is my first year growing vegetables in my garden. I usually just concentrate on flowers. I bought 6 little bok choy plants and they're doing quite nicely. I planted them around May 15th. The leaves are getting bigger and are a lovely dark green. One of them, though, is growing a great big tall stem of yellow flowers. Should I just leave it alone? Should I be worried that the other plants don't have flowers as well? And when are they going to start looking like the bok choy that I see in the market -- they look more like the picture at the top of this forum.
