Origin & Breeding History: 'KOIBID1510' was bred and developed by the breeder, Koichiro Nishikawa, in Nagi-cho, Katsuta-gun, Okayama-ken, Japan. It originated from a controlled self-pollinated cross of the Bidens ferulifolia variety 'k-1105' conducted in January 2011, in Okayama-ken, Japan. The new variety 'KOIBID1510' was selected as a single plant in May 2011 for its growth habit, branching characteristics, length of flowering period, peduncle strength and flower colour. 'KOIBID1510' was first propagated asexually by tip cuttings in June 2011, in Okayama-ken, Japan.

Tests & Trials: The comparative trial for 'KOIBID1510' was conducted in a polyhouse during the summer of 2018 at BioFlora Inc. in St. Thomas, Ontario. It included a total of 20 plants each of the candidate and reference variety. Rooted cuttings were transplanted into 15 cm pots on April 18, 2018. The observations and measurements were taken from 10 plants, or parts of plants, of each variety on June 7, 2018. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
