Origin & Breeding History: 'Stans001' was discovered as a chance seedling from an unknown plant of Argyranthemum frutescens, growing in Hobbs, New Mexico, USA in March 2001. The new variety was selected based on criteria for flower colour, good branching, compact growth habit and floriferous appearance. Asexual reproduction of the new variety by vegetative cuttings was first conducted in the Spring of 2002 in Hobbs, New Mexico, USA.

Tests & Trials: 'Stans001' was tested during the spring of 2006 in St. Thomas, Ontario. The trial included 15 plants of each variety. All plants were grown from rooted cuttings transplanted into 15 cm pots on March 30, 2006. Observations and measurements were taken from 10 plants of each variety on May 26, 2006. All colour measurements were made using the 2001 RHS colour chart.
