can 3 or 4 small shefflera plants be twisted together
What is this plant? 4 are twisted together at base. It's been growing for several years.
The photo is dark, but from what I can see it does appear to be schefflera with multiple stems that have been "pleached" (woven/braided) at the base for a unique aesthetic effect.
It's not necessarily good for the plant in the long term to have potential constricting wrap-around growth occurring, but not outright harmful as long as it is doing okay that way.
Problems with circulation (uptake of water and nutrients) could develop in the future and cause decline and die-back of one or more stems and part of the foliar canopy. But that is not a certainty and it may do okay.
