Origin & Breeding History: 'LPDC Podaras' originated as a naturally occurring branch mutation of an unnamed seedling within a seedling population of the species. The mutation was observed in 2005 in an indoor nursery trial bed on the campus of Cornell University in Ithaca, New York, United States. The new variety was propagated by softwood cuttings at the Cornell University campus greenhouse in November of 2005 to assess its rooting ability. It underwent further testing at the same location from 2006 to 2007. 'LPDC Podaras' was originally selected based on it variegated foliage and further selected at a later time based on the length of internodes and the growth habit.

Tests & Trials: Trials for 'LPDC Podaras' were conducted outdoors at Variety Rights Management in Oxford Station, Ontario during the summer of 2013. The trial consisted of 12 plants of each variety grown in 27 cm pots spaced 45 cm apart. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
