Oak Acorn Plum Gall

Pictured is Oak Acorn Plum Gall. It was IDed for me by some folks at the Texas Fruiting Plant Growers (Texas Rare Fruit Growers) FB page. I have seen it during the past week on hike/bike trails along Cypress Creek in Cypress, Texas, northwest of Houston, Texas. And, of course, I always found them under Oak trees!

The galls are the Oak tree’s reaction to the small, harmless wasp Amphibolips quercusjuglans

You can find out lots of cool info about plants and animals on Island Creek Elementary’s Website.

    One of my favorite quotes is from Eden Philpotts: “The universe is full of magical things, patiently waiting for our wits to grow sharper.”
    Learning in nature helps our wits grow sharper faster, don’t you think? Keep up your good work!

      Agreed! I’ve studied math and physics and chemistry, but, when I started learning foraging, tracking, botany, zoology, ecology and biology — by getting out to observe and think (and by listening to lots of books) — I felt like I was learning what science was for the first time in my life. The first-hand experience and independent thought is essential.
