Abstract: A plant border system includes a flat and a plant tray. The flat defines a flat cavity and a flat top opening communicating with the flat cavity. An upstanding rim surrounds at least a portion of the flat top opening. The plant tray defines a tray cavity and a tray top opening communicating with the tray cavity. The tray cavity has a tray width and a tray length that is greater than the tray width. The plant tray includes a collar surrounding at least a portion of the tray top opening, the collar defining a downwardly opening channel. The flat is adapted to receive the plant tray in the flat cavity such that the rim is received in the channel and the flat is thereby structurally reinforced by the plant tray to resist flexure.

Abstract: A plant border assembly includes a plant tray defining a cavity and a top opening communicating with the cavity. The cavity has a width and a length that is greater than the width. The plant border assembly further includes a plant border including a growing medium disposed in the cavity and a strip of plants disposed in the growing medium in the cavity. The plant tray is adapted to allow removal of the plant border from the plant tray without lifting the plant border through the top opening.

Abstract: ‘LM400’ is a distinctive variety of Lomandra longifolia which is characterized by the combination of its dwarf, compact growth habit; its fine, narrow leaf blade; and the blue/grey overall color of the leaf blade.

Abstract: ‘DBB03’ is a distinctive variety of Dianella caerulea, which is characterized by the combination of its open growth, a blue-green foliage, pale blue flowers, slightly spreading and semi-compact growth habit, and an absence of canes, which is unusual for a Dianella caerulea, particularly when compared to the ‘Sydney Ecotype’. ‘DBB03’ is also less prone to falling over than the parent type.

Abstract: ‘DCMP01’ is a distinctive variety of Dianella caerulea which is characterized by the combination of its dense growth, slightly spreading and compact growth habit, purple-blue flower color, and short canes with very short internodes, which is unusual for a Dianella caerulea, particularly when compared to the ‘Sydney Ecotype’. In addition, ‘DCMP01’ is less prone to falling over than the parent type.

Abstract: ‘DRG04’ is a distinctive variety of Dianella revoluta, which is characterized by the combination of a dense compact clumping habit with red basal shoots and a slight weeping of clumps with age. ‘DRG04’ is further characterized by its glaucous leaves, which result in a two-toned leaf color when viewed from a distance, with a glossy green upper side leaf color and a dull green (slightly blue-toned) lower side leaf color. When observed up-close the leaves are a yellow-green. ‘DRG04’ is also distinguished by the ability to be easily and productively propagated by division.

Abstract: ‘DCNCO’ is a distinctive variety of Dianella caerulea which is characterized by the combination of its densely tufted, slightly spreading and semi-compact growth habit, pale blue flower colour, a general absence of canes, and a reduced tendency to fall over at maturity.

Abstract: ‘TR20’ is a distinctive variety of Dianella tasmanica with a clumping habit, which is characterized by the combination of a large flower cluster with blue flowers, green foliage with red basal shoots and red green lower leaf areas, which changes to a reddish-green foliage with red leaf margins in cooler seasons, and, in the Spring, TR20 leaf colour is yellow-green with some red leaf margins and red basal shoots and red-green lower leaf areas.

Abstract: ‘PHORD1’ is a distinctive variety of Phormium tenax characterized by a medium growth habit with a medium shoot density when compared with common Phormium tenax which has a variable growth form ranging from short to tall plant height and sparse to dense shoot density. In addition, ‘PHORD1’ has a deep red leaf color, whereas common Phormium tenax has a purple leaf color. ‘PHORD1’ also has strong resistance to Phytophthora root rot, whereas common Phormium tenax has week resistance.

Abstract: ‘DTN03’ is a distinctive variety of Dianella revoluta, which is characterized by its combination of bluish-green leaf color, strong leaf glaucosity, very short height, erect growth habit, very dense shoots with very short internodes, and narrow leaf blade. Pale blue flowers on stems up to 50 cm high typically develop in spring and early summer and are followed by green berries.
