Here's a quiz for you, Jim. Answer it correctly for an acorn. Wrong answer (guess) and I get the acorn.
Anyone else can chime in but only Jim is eligible for the acorn gift.
I looked at the close-up (third picture) and want you to tell me what the plant is growing on. Not the cork, that's easy, but the dark substance that is (mostly) holding the roots against the cork. Ursula, I don't think you will see this on your plant, so there is no need to peek at yours.
I just love mysteries and challenges!
