A novel collapsible plant support includes a collapsible coil adapted to rest on a flat surface. In a particular embodiment, the collapsible plant support includes a plurality of vertical support structures coupled to the collapsible coil so as to provide additional support. In another particular embodiment, a collapsible plant support includes plant receptacle receiving element that supports both a collapsible coil and also a plant receptacle. In a more particular embodiment, the plant receptacle receiving element includes fluid ducts for connecting multiple plant receptacle receiving elements into a fluid network. In another embodiment, the coil is disposed within a helical sleeve coupled to a flexible, cylindrical mesh.

A clamping device (10) comprises a body (30), a clamping arrangement (50) in the body for clamping a flexible elongate member (12). A first cooperating formation (36) cooperates with a second cooperating formation (18). The second cooperating formation is part of a support arrangement (14) to support the clamping device. The first cooperating formation comprises a pair of opposed side portions (38A) and a bridging portion (38B) extending between the side portions.

Modular trellis sections of aesthetic appearance that are manually portable and easily installed in residential or commercial gardens, and that can be arrayed to form a linear, a partially enclosed, or an entirely enclosed trellis fence are configured as a basic rectilinear frame formed from a pair of rigid generally parallel vertical rods to which are permanently secured in co-planar relation a first horizontal rod extending between the upper ends of the vertical rods and a second horizontal rod at a predetermined distance from the lower free ends of the vertical rods to define a pair of supporting legs, and vertically spaced rigid supporting hooks that are secured in co-planar relation to the inner facing surfaces of the vertical rods, the openings of the supporting hooks being configured and dimensioned to receive horizontal rails and open mesh wire panels that extend between and link the trellis sections to form a fence. The several configurations of trellis sections, along with other accessories are well suited for sale as kits for installation by both residential gardeners and commercial growers.

The present invention relates to a hub comprising i) a first hub member, comprising a first plurality of spar receiving zones; and ii) a second hub member, comprising a second plurality of spar receiving zones; wherein: a) the first and second hub members are located immediately adjacent to each other and share a common, substantially central axis; b) the first hub member is not identical to the second hub member; and c) each spar receiving zone of the first and second plurality of spar receiving zones is adapted to receive a spar, wherein the spar is adapted to link two hubs. The present invention further relates to methods of assembling three dimensional structures incorporating such hubs, including but not limited to trellis.

A system for building a reconfigurable trellis includes at least one slidable pole connector configured to slide along a pole having either a circular or rectangular cross-section. The slidable pole connector includes a first portion configured to slide along a first pole and a second portion extending perpendicularly from the first portion and configured to receive an end of a second pole. The first portion may be in the form of a sleeve, which may be unitary or may include two detachably connected parts. A tightening mechanism may be provided to secure the first portion against the first pole and to prevent further sliding of the first portion when the connector is in a desired position. Several slidable pole connectors may be used with one another and with strand or rope connectors to secure a plurality of vertical poles, horizontal poles, and ropes, cables, strings, or or wires to one another in a variety of adjustable configurations.
