These blueberry shots come from different plants around the lake. In fact, they might be different species. I won't try to nail that down at this time, only to recognize that the probability exists.
From a few weeks ago.
I've photographed this bush since winter when only those galls were present. This shot was taken in early April. I just found out that the Blueberry Stem Gall Wasp, Hemadas
nubilipennis, is responsible for these galls.
Here's the same bush a week or so ago. It doesn't show the galls that well here but they're still there.
I found that little bit of blue most curious.
And here with most of the blossoms gone by, we can see the early development of the berries. I think as the berries plump up that the pointy edges will become that little crown on each berry.
