Variety Description

Varieties used for comparison: 'OHMADSAOM' (Madeira Ivory) and 'Argyrantis' (Molimba Helio White)

Summary: 'Argyparawi' has shorter plants than 'OHMADSAOM' and narrower plants than both reference varieties. 'Argyparawi' has narrower leaf blades and smaller leaf blade lateral lobes than 'Argyrantis'. The flowers of 'Argyparawi' are larger in diameter with fewer ray florets per flower than those of the reference varieties. The ray florets of 'Argyparawi' have a downward attitude when newly opened and develop a horizontal attitude as they mature whereas those of the reference varieties are only horizontal. The flowers of 'Argyparawi' have a whorl of petaloid disc florets at the base of the ray florets whereas the reference varieties do not.

Description:

PLANT: upright bushy growth habit, short to medium height, narrow to medium width, medium foliage density

LEAF BLADE: medium length, narrow, attenuate base, cuspidate apex, dark blue green
LEAF BLADE LATERAL LOBE: short to medium length, very narrow to narrow

PEDUNCLE: short to medium length, medium thickness
FLOWER: very broad diameter, single
RAY FLORET: average of 13.2 per flower, downward attitude upon opening and becoming horizontal with age, slightly reflexed along longitudinal axis, long to very long, broad to very broad, 2.8:1 ratio of length to width, white on upper and lower sides
FLORET DISC: whorl of white petaloid disc florets present, yellow before dehiscence, yellow orange after dehiscence

Origin & Breeding History: 'Argyparawi' was developed by the breeder, Anna M.W.P. Houbraken, an employee of Syngenta Seeds B.V. in Enkhuizen, The Netherlands. It originated from a controlled cross made in August 2002 in Enkhuizen, The Netherlands, between the female parent designated 'D0116-2' and mixed pollen from unidentified Argyranthemum frutescens plants. 'Argyparawi' was selected from the resultant progeny as a single plant in August 2003 based on its' foliage colour and large flowers.

Tests & Trials: Trials for 'Argyparawi' were conducted in a polyhouse during the spring of 2007 at BioFlora Inc. in St. Thomas, Ontario. The trials included 15 plants per variety. Rooted cuttings were transplanted into 15 cm pots on March 23, 2007. Measured characteristics were based on measurements taken from 10 plants or parts of plants on May 25, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
