Can you see it? The first bud is forming. It's right in the center of the photo, at the end of the yellow ovary, which will turn into a fruit after the flower is pollinated. There are several other buds forming down there as well.
I took the photo at about 1pm this afternoon. The plants have been growing great guns this week. Here is the hill that I've been photographing, and the entire patch, for comparison with my last photo of the patch on July 31.
Monday morning we'll be irrigating the garden, but on Tuesday I'll be back to see how the bud is doing. It has a few days of growth before it will be ready to open.
