Variety used for comparison: 'Zone 10' (Mystic Dreamer)

Summary: 'VDTG43' is a Dahlia variety which has shorter plants and a shorter peduncle than the reference variety 'Zone 10'. The flower heads of 'VDTG43' are positioned moderately above the foliage, whereas the flower heads of 'Zone 10' are high above the foliage. 'VDTG43' has smaller diameter flower heads than 'Zone 10'. The two varieties also differ in colour of the ray florets.

LEAF: predominantly pinnate (5 to 7 leaflets), strong wing, medium length, narrow width, green tinged with purple, medium glossiness, smooth or very weakly rugose texture, depressed veins
LEAFLET: ovate shape, cuneate to obtuse base, many shallow to medium depth incisions
PEDUNCLE: medium to long, brownish red to purple

FLOWER HEAD: moderately above foliage, upright to semi-upright, single, daisy type disc, no collar segments, few ray florets
RAY FLORET: keeled upper surface, two keels, moderately concave in cross section at mid-point, weakly concave at 3/4 point from base, weakly revolute to flat margin along distal quarter, incurved longitudinal axis, very weak curvature of distal quarter, absent or very weak twisting, mamillate apex
RAY FLORET INNER SIDE: more than two colours, violet main colour with diffused purple stripes on basal half, solid or nearly solid red at base

DISC: medium diameter relative to flower head, red brown before anther dehiscence, yellow to orange at dehiscence

Origin & Breeding History: 'VDTG43' was developed at the nursery of Fa. Gebr. Verwer, in Lisse, The Netherlands, and originated from the open pollinated cross between the female parent, a Dahlia plant identified as 'R', and pollen of an unidentified Dahlia plant. The cross took place in the summer of 2003. A single seedling was selected in the summer of 2004, based on criteria for flower form (single), colour, compact plant habit and dark foliage colour.

Tests & Trials: 'VDTG43' was tested in outdoor trials during the spring of 2008 in St. Thomas, Ontario. The trial consisted of a total of 15 plants per variety. All plants were grown from rooted cuttings and transplanted into 20 cm pots on May 15, 2008. Observations and measurements were taken from 10 plants of each variety on July 8, 2008. All colour measurements were made using the 2001 Royal Horticultural Society (RHS) Colour Chart.
