Variety Description

Varieties used for comparison: 'Cobsing' (Comet Pink) and 'Bonmadpipa' (Madeira Pink)

Summary: The leaves of 'Argypink' are longer than those of 'Cobsing' and narrower than those of 'Bonmadpipa'. The lateral lobes of the leaves of 'Argypink' are narrower than those of 'Bonmadpipa'. 'Argypink' has single type flowers while both reference varieties are semi-double. The flowers of 'Argypink' have a smaller diameter than those of both reference varieties. 'Argypink' differs from both reference varieties in the pink colour of the upper side of the ray florets. The discs of 'Argypink' are narrower than those of both reference varieties.

Description:

PLANT: rounded growth habit, medium height, dense, stem anthocyanin colouration present

LEAF BLADE: short to medium length, narrow, blue green on upper side
LEAF BLADE LATERAL LOBE: short to medium length, very narrow to narrow, shallow depth of marginal insicions

FLOWER: single type, small diameter, early flowering
RAY FLORET: straight curvature of longitudinal axis, short to medium length, medium to wide, two coloured on upper side, when newly opened the upper side is almost white to very light pink, when fully opened the upper side is violet (RHS 75D) with strong overlay of darker violet (RHS 75B), white at base on upper side, blue pink (RHS N74D) with tones of darker blue pink (RHS 72D) on lower side
FLORET DISC: very small diameter, yellow orange

Origin & Breeding History: 'Argypink' originated from an open pollination that took place in August 2003 between the female parent identified as G0101-4 and pollen from an unidentified Argyranthemum frutescens. The new variety was bred and developped by the breeder Anna M.W.P. Houbraken, while employed at Syngenta Seeds B.V., Enkhuizen, The Netherlands. 'Argypink' was selected as a single seedling in August 2004 based on compact growth habit and flower colour. Asexual reproduction by cuttings was first conducted August 2003 in Enkhuizen, The Netherlands.

Tests & Trials: Trials for 'Argypink' were conducted in a polyhouse during the spring of 2008 in St. Thomas, Ontario. The trial included a total of 15 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings and transplanted into 11 cm pots on March 19, 2008. Observations and measurements were taken from 10 plants of each variety on May 23, 2008. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
