Abstract

Abstract A vertically extending rod-like trunk member carries a plurality of limb assemblies in a circumferential array with each limb assembly including a straight main limb and a number of cross limbs extending outwardly therefrom at spaced longitudinal positions. The upper end of each main limb is coupled to the tree. At some distance below this coupling point for each limb assembly, an axially shiftable collar pivotably supports a radial array of arms which, in turn are pivotably coupled to the main limb of each limb assembly. Shifting of the axially shiftable member causes the main limbs to move from a substantially parallel inboard position relative to the rod-like trunk member to an outboard position in which the main limbs incline downwardly and outwardly to complete a shrub of conical configuration.
