The stipules are medium in size and the terminal leaflet is broadly ovate, with weak waviness of the margin, an acuminate tip and a symmetrical, truncate base. There are an average of four pairs of primary leaflets, which are medium sized and moderately ovate with an acuminate tip and asymmetrical, truncate base. There are 5 to 9 secondary and tertiary leaflets.

Origin & Breeding History: 'FL 1879' originated from the cross 'Snowden' x FL 1207, made in Rhinelander, Wisconsin, USA in 1989. Botanical seeds of the cross were grown in the greenhouse in 1989. All of the tubers from each selected plant were retained and from this point on each selected individual was propagated clonally. Tubers were planted in 1990 and 1991. 'FL 1879' was selected from plants grown in 1991 and was designated as RD268-90-6. The variety was given the new designation 'FL 1879' in 1994.

Tests & Trials: Tests and trials for 'FL 1879' were conducted in 2000 at Vauxhall, Alberta. The varieties were planted in rows 30 metres long with 100 cm between the rows and the plants were spaced 30 cm apart within the row.
