Abstract
Greenhouse plants are displayed on horizontal shelves supported between side rails extending at an angle between vertical support posts, the posts being interconnected in pairs between confronting vertical grooves formed in the posts. Each shelf is assembled from elongated sections held in parallel spaced relation to each other by spacers at the longitudinal ends of the shelf which are received within grooves formed in the side rails.
