Here is an example using Vertex Tools. Takes a few minutes. You probably already have something, but I think this would be faster than a tree plugin. I didn't texture it properly but you can have these if interested. I made cylinders with multiple mid circles. Lined them up and used VT gizmo (gently) all at once on multiple soft selections.
VT cost but you won't regret it, and you also have a chance to support ruby development.
