Abstract: Vertically and horizontally disposed planters including light-transmitting, convex, upwardly or outwardly extending enclosures are disclosed. The planter enclosures extend in a convex manner to enclose with a light transmitting section the earthen matter from which the plants grow as well as enclosing at least in part a growing plant itself. The vertically disposed planters comprise outwardly extending enclosures which are supported in vertical, preferably planar members such as doors and panels. The horizontally disposed planters comprise enclosures which comprise a downwardly extending lower convex portion enclosing the earthen matter and an upwardly extending light-transmitting portion enclosing, at least in part, a growing plant. The horizontally disposed planters are supported in horizontal preferably planar members such as skylights and roofs. For essentially completely enclosed planters, fixed and closable openings are also disclosed. These permit the passage of air, moisture, nourishment, etc.
