Variety Description

Varieties used for comparison: 'Sutcatrabl' (Cabana Trailing Blue) and 'Bacoble' (Blue Showers)

Summary: 'KLESG05178' has weaker intensity of anthocyanin colouration of the stem and lighter green leaves than the reference varieties. 'KLESG05178' has a shorter calyx, smaller corolla diameter with narrower lobes and shorter corolla tube than 'Sutcatrabl'. The position of the anthers relative to the corolla tube opening is higher above the opening for 'KLESG05178' than either reference variety.


PLANT: horizontal to semi-drooping growth habit, moderate to dense branching
STEM: weak to moderate anthocyanin colouration

LEAF: simple type
LEAF BLADE: ovate, dentate margin, medium number of marginal teeth, no variegation, light green on upper side, very sparse pubescence on upper side

INFLORESCENCE: cluster type, positioned in both terminal and axillary locations along stem
PEDICEL: medium thick
COROLLA: partially fused corolla lobes, strong degree of lobing, weak undulation of margin, violet on upper side
COROLLA TUBE: straight attitude, funnel shape, dense and short pubescence on outer side, orange on inner side
ANTHERS: positioned high above corolla tube opening

Origin & Breeding History: 'KLESG05178' was developed in Stuttgart, Germany. It originated from an open pollinated cross conducted in July 2002 between an unnamed proprietary seedling as the female parent and an unknown male parent. In May 2003, 500 seedlings were selected in Stuttgart based on their flower colour, good branching habit and flowering time. These seedlings were evaluated for flower colour, branching, growth habit and resistance to disease during greenhouse trials conducted in 2003-2004. In April 2004, one of these seedlings, 'W 024', was designated as 'KLESG05178'.

Tests & Trials: Trials for 'KLESG05178' were conducted in a poly-house during the summer of 2007 at BioFlora Inc. in St. Thomas, Ontario. The trial included a total of fifteen (15) plants per variety. All plants were grown from rooted cuttings and transplanted into 15 cm pots on May 9, 2007. Observations and measurements were taken from ten (10) plants or parts of plants on June 13-15, 2007. All colour determinations were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
