It originates from a seedling selected from Oxalis regnellii in Hungary in 1993. The final selection was made in 2001 based on flower colour, foliage colour and excellent longevity.
Tests & Trials: The test and trial for 'Jroxburwi' was conducted in a polyhouse during the fall of 2006 at BioFlora Inc. in St. Thomas, Ontario. The trial included 15 plants of each variety. Rooted cuttings were transplanted into 15 cm pots. Observations and measurements were taken from 10 plants of each variety on October 4, 2006. All colour measurements were made using the Royal Horticultural Society (RHS) Colour Chart 2001.
