LEAF: medium length, medium to broad, broad wedged and asymmetrical base
LATERAL LOBE: mostly parallel margins of sinus
LOWER LOBE: medium to long, medium to deep sinus
FLOWER HEAD: double, decorative sub-type, chromatic self colour type, pink colour group with outer ray florets of weak intensity and inner ray florets of weak to moderate intensity, small to medium diameter, no bracts among ray florets

Origin & Breeding History: 'Yonew York' is a product from a planned breeding program conducted by the breeder, Mrs. Wendy R. Bergman, an employee of Yoder Brothers, Inc. in Barberton, Ohio, USA. It originated from a cross made in February 2000 in Salinas, California, USA between a proprietary Chrysanthemum seedling selection designated 'YB-6277' as the female parent and another proprietary Chrysanthemum seedling selection designated 'YB-4934' as the male parent. 'Yonew York' was selected in November 2000 in Fort Myers, Florida, USA based on its uniform plant growth habit, desirable inflorescence form and floret colours, fast response time and excellent post production longevity.
Tests & Trials: Trials for 'Yonew York' were conducted in the fall of 2006 at Yoder Canada Ltd. in Leamington, Ontario. They were performed under greenhouse conditions similar to those used in commercial Chrysanthemum production. 40 unrooted cuttings per variety were directly stuck into 15 cm pots with 4 cuttings per pot and 10 pots per variety. The pots were spaced 30 cm apart. The plants were pinched once prior to short day treatment. All plants had the centre bud removed. Measured characteristics were based on measurements taken from 10 plants or parts of plants on November 2, 2006. All colour determinations were made using the 2001 Royal Horticulture Society (RHS) Colour Chart.
