Origin & Breeding History: 'Pink Truffles' originated from an isolation block line breeding method conducted in 2009 in Waseca, Minnesota, USA. The female or seed parent was Baptisia australis and pollen parent was from an isolation block containing advanced hybrids of B. minor, B. sphaerocarpa, B. alba, or B. cinerea. The resulting seeds were collected and sown in Zeeland, Michigan, USA in the fall of 2009. In 2012, 'Pink Truffles' was selected for its flower colour and plant growth habit. 'Pink Truffles' is primarily propagated asexually using stem cuttings.

Tests & Trials:
The comparative trial for 'Pink Truffles' was conducted in a polyhouse during the spring of 2015 at Variety Rights Management in Oxford Station, Ontario. There were 15 plants of the candidate variety and reference variety. Each plant was grown in a 23 cm diameter pot, one plant per pot with 45 cm spacing between the pots. Observations and measurements were taken from 10 plants or parts of plants of each variety. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
