Variety Description

Varieties used for comparison: 'Osoutis' (Soprano Purple) and 'Wildside'

Summary: 'Osjampurim' differs from the reference varieties, 'Wildside' and 'Osoutis', mainly in plant height, intensity of anthocyanin colouration of the shoots, ray floret colour, colour of disc before dehiscence and disc diameter. The plants of 'Osjampurim' are short to medium in height wheres they are very short in 'Wildside' and medium to tall in 'Osoutis'. The intensity of anthocyanin colouration is absent to weak at the base of the shoots of 'Osjampurim' whereas it is medium to strong in 'Wildside' and weak to medium in 'Osoutis'. The secondary colour on the upper side of the ray florets of 'Osjampurim' is purple whereas it is a darker purple in 'Wildside' and violet in 'Osoutis'. The main colour on the lower side of the ray florets of 'Osjampurim' is violet with brown-purple stripes whereas it is a pale violet background with red-black stripes in 'Wildside' and yellow-brown with dark blue stripes in 'Osoutis'. Before dehiscence, the disc of 'Osjampurim' is purple whereas it is very light blue in 'Wildside' and dark blue with purple base in 'Osoutis'. The disc diameter is larger in 'Osjampurim' than it is in both reference varieties.

Description:

PLANT: erect shoots with absent to weak anthocyanin at the base, short to medium in height

LEAF: very short to short, narrow, obovate shape, shallow to medium depth of incisions of margins, no variegation, medium green on the upper side

FLOWER: short peduncle, one or two complete ray floret whorls, narrow inflorescence diameter
RAY FLORET: short, medium in width, oblanceolate in shape, with a rounded-dentate apex, reflexing present when newly opened only, no inward rolling of longitudinal margins, horizontal attitude, violet with purple to blue pink stripes on the upper side, violet with brown-purple stripes on the lower side
DISC: purple before dehiscence

Origin & Breeding History: 'Osjampurim' originated from the cross 'C0298-5', as the female parent, with a mix of pollen from unidentified male Osteospermum ecklonis plants. The controlled cross was conducted in July 1999 in Enkhuizen, the Netherlands. 'Osecspovan' was selected from the resultant progeny as a single plant in June 2000 based on compact plant size, large flower size and flower quality. Asexual reproduction by cuttings was first conducted in June 2001 in Enkhuizen, the Netherlands.

Tests & Trials: The trials for 'Osjampurim' were conducted in a polyhouse at BioFlora in St. Thomas, Ontario, during the spring of 2007. The trials included 15 plants of each variety grown from rooted cuttings and transplanted into 11 cm pots. Observations and measurements were taken from 10 plants of each variety. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart.
