I've planted my favorite piece, a Western Red Cedar seedling. It is a volunteer that started growing in one of my flowerpots in the backyard. The cedar is a very important tree around here, for a long time. The native people of the area used every part of it. I love working with cedar and there are other DIY threads to come that feature cedar. It is the centerpiece of this work.
Here's a shot taken from the mouth of the jar. You can see the different kinds of moss, including the brownish stripe moving from 8 o'clock to the center. That's Leptinilla squalida, Platt's Brass Buttons. I like the tiny fernlike leaves. Also, around the perimeter near the 8 o'clock is a tiny Sword Fern, another volunteer I plucked off of one of my lilacs in the back yard.
A shot from the outside showing more of the plants. There's a spearmint (or some kind of mint with bronzy purple new growth in the foreground. There are a couple pretty plants whose names I do not yet know with round leaves. One has a delicate white cluster of flowers at the top.
You can see the other plants a little better here. A word about the glass and the quality of the photo. Working in this jar while looking through the side of the jar was difficult. All the wavy distortions made for some... imperfect adjustments as I tried to manipulate the plants. They look fine, but it was weird looking through this funhouse lens.
