ABSTRACT:
A plant container including at least one section of flexible material having an inner and an outer surface. The inner surface is formed at least in part by a lattice of recesses, and at least some of the recesses converge toward a hole through the material. The outer surface is formed at least in part by a lattice of protuberances at the same relative positional arrangement as the recesses. Each section is formed as a parallelogram having two acute angles and two obtuse angles. Each section is arranged to form a cylinder with adjacent ends overlapping and the protuberances on the outer surface of one end nesting within the recesses of the inner surface of the adjacent end at the overlap.
