I planted up a dwarf Horsetail in this pot about 4 years ago and promptly neglected it among the others on my bench. Over the four years I had a few neighbouring plants move in of there own accord and have now made this their home. It’s also made my feeble efforts at kusamono look average.

New additions include, Rowan, Cotoneaster, Viola, and whatever the hell the big tall thing is. No clue, obviously brought in by the birds.
