It's been a month since I last checked in on my acorn rainbow. The leaves are off the trees now and my mossy stump is clearly visible against the dying vegetation. The moss is changing color too, offering a shocking lime green against the brown oak leaves.
Only three of the original 6 acorns are visible. The other three have either been carried off by curious critters or are hidden beneath the leaf litter.
The purple acorn is nestled in a bed of sporophytes.
