RHS Chart - edition 2007 Origin and Breeding Open-pollination: approximately 1000 seedlings of common Lepironia articulata were raised in the autumn of 2005. In Jan 2006 one seedling was identified as having distinctly different, twisted growing foliage. The seedling was selected and grown to a mature height. It was found to grow uniform and 5 successive cycles of vegetative propagation have proven to be true to type also. The plant was given the name ‘LA20’. Breeder: Craig Waters, Wauchope, NSW. Choice of Comparators Characteristics used for grouping varieties to identify the most similar Variety of Common Knowledge Organ/Plant Part Context State of Expression in Group of Varieties Plant type herbaceous perennial Plant time of beginning of flowering medium Stem degree of hairiness absent Leaf presence of variegation absent Most Similar Varieties of Common Knowledge identified (VCK) Name Comments Lepironia articulata common form There is no variety of common knowledge; therefore the common form of the species was used as the comparator. Variety Description and Distinctness - Characteristics which distinguish the candidate from one or more of the comparators are marked with a tick.
