I have a couple of spruce stumps that we left about 4' tall. I'd like to attach a large coir lined planter to the top (or some other natural looking container). I think it could look like a big topiary/standard, or at least that's what I'd like to see.
"...and don't think the garden loses its ecstasy in winter. It's quiet, but the roots are down there riotous." Rumi
