The variety was grown each year after it was discovered and tested at the Agriculture & Agri-Food Canada Research Station in Lethbridge, Alberta.

Tests & Trials: 'Rande's Golden Gem' was tested in Golden, British Columbia in 2005. The trial included 30 plants of each variety grown in 3 replications with 10 plants/replication.
