A few weeks ago I planted Spinach in a couple of locations. One is in a 24 inch planter. All of it is doing fine, but the container crop seems to be flowering. There are no more than three sets of leaves and now they are getting a tight bunch of, something. It's a tight short vertical stem growing in the center of the plant. It is a stem with tons of very small, very tight circular things. Could the plant be flowering? On the one plant where I removed the stem there are now two stems growing. Interesting, but I am going to want to eat this stuff.
