This bottlebrush shrub/tree and another smaller one with it appeared in a plant pot of their own accord. I planted them out to a suitable place. The trunks are only 6" / 15cm apart due to the roots having intertwined themselves in the pot. The yellowness of this one is faded when viewed on my laptop but shows brilliantly on an extension screen. This is the first year it has flowered. See PiPs. September 2024.
