Variety Description

Variety used for comparison: 'Variegata'

Summary: 'Dappled Light' is a ground ivy variety which has broader leaves than the reference variety 'Variegata'. The main colour of the leaves of 'Dappled Light' is medium to yellow green, whereas 'Variegata' leaves have a grey green main colour. The major difference between the two varieties is the distribution of the secondary colour on the upper side of the leaf blade. In 'Dappled Light' the secondary colour is speckled over most of the upper surface, whereas in 'Variegata' the secondary colour is restricted to random blotches of whitish colour, mostly near the leaf margins.


PLANT: trailing growth habit, dense foliage

STEM: medium thickness, square in cross section, light green colour, weak to strong anthocyanin colouration, medium pubescence

LEAF: opposite arrangement, simple, reniform shape, crenate margin with moderately deep incisions, cordate base, moderate pubescence on upper side of blade, sparse pubescence on lower side (mostly on veins), medium blistering, whitish secondary colour in speckled pattern, weak anthocyanin on petiole

Origin & Breeding History: 'Dappled Light' was discovered and developed by the breeder at Cottage Grove, Oregon, U.S.A. The variety originated from a branch mutation of Glechoma hederacea 'Variegata', discovered in May 2001. It was selected based on leaf variegation, rapid growth, stem colour and overall foliage appearance. Asexual reproduction by vegetative cuttings was first conducted in May 2001 in Cottage Grove, Oregon.

Tests & Trials: The tests and trials for 'Dappled Light' were conducted in a polyhouse during the summer of 2006 in St. Thomas, Ontario. The trial included a total of 15 plants of the candidate variety and reference variety. All plants were grown from rooted cuttings and transplanted into 11 cm pots on May 10, 2006. Observations and measurements were taken from 10 plants of each variety on July 11, 2006. All colour measurements were made using the RHS Colour Chart 2001.
