Origin & Breeding History: 'Peters Goldteppich' is a product of a planned breeding program conducted by Mr. Peter Wickl-Friedl of Nev St. Johann, Switzerland. It was discovered and selected in the spring of 1996 in Nev St. Johann, Switzerland.

Tests & Trials: Tests and trials were conducted in a polyhouse during the summer of 2002 by BioFlora Inc. in St. Thomas, Ontario. Trials consisted of 15 plants of each, which were grown from rooted cuttings transplanted into 11 cm pots on May 18, 2002. Observations and measurements were taken on ten plants of each variety, and colour measurements were made using RHS colour chart 2001.
