An adjustable plant support system with a vertically oriented shaft, an adjustable clamp assembly and a horizontally oriented shaft. The clamp assembly is capable of releasably retaining both the vertical shaft and the horizontal shaft. A preferred embodiment includes the clamp assembly having a rigid body with a vertically disposed aperture, a horizontally disposed aperture and a U shaped cutout area located in front of the apertures that receives a cam type clamping lever that is rotatably pinned to the remaining upper and lower legs formed by the U shaped cutout. The vertical aperture and the horizontal aperture are in adjoining proximity to each other so that when the shafts are in place, the cam lever pushes against the vertical shaft which in turn pushes against the horizontal shaft thereby locking them in place.
