plant named ‘LFKULI19’

Abstract

A new cultivar of Kunzea ericoides named ‘LFKULI19’ is disclosed and is distinguishable by its weeping plant habit and dense stems and foliage which is very fine and soft to the touch. The leaves of ‘LFKULI19’ is aromatic and spicy. ‘LFKULI19’ is heat and drought tolerant and is hardy to USDA Zone 8. ‘LFKULI19’ rarely produces flowers.

Description

Genus and species: Kunzea ericoides.

Variety denomination: ‘LFKULI19’.

BACKGROUND

The present disclosure relates to a new and distinct cultivar of Kunzea ericoides, commonly known as Kanuka and a native plant of New Zealand. In its native form, Kunzea ericoides grows as a medium to large sized tree with coarse foliage.

‘LFKULI19’ was discovered in 2018 by the inventor as a naturally occurring branch sport (a single shoot) with very fine foliage which was growing on a plant of Kunzea ericoides ‘Little Fox’ (unpatented). The sport parent ‘Little Fox’ was growing in a cultivated area in Waipu, New Zealand. The inventor excised and asexually propagated the discovered sport using the method of stem cuttings. The inventor has confirmed that ‘LFKULI19’ is stable and reproduces true to type in successive generations of asexual reproduction.

SUMMARY

The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘LFKULI19’. ‘LFKULI19’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without however, any variance in genotype.

• • 1. ‘LFKULI19’ exhibits a dense slightly mounding weeping plant habit.
  • 2. The foliage of ‘LFKULI19’ is very fine and soft to the touch.
  • 3. The foliage of ‘LFKULI19’ is aromatic and spicy.
  • 4. Plants achieve a height and spread of 15 cm by 60 cm after three years growth from planting a rooted cutting.
  • 5. ‘LFKULI19’ rarely produces flowers.
  • 6. ‘LFKULI19’ is heat and drought tolerant and is hardy to USDA Zone 8.

DESCRIPTION OF THE PHOTOGRAPH

The accompanying color photograph illustrates a three year old plant of ‘LFKULI19’ which has been growing out of doors in a 5-gallon container in Santa Barbara, Calif. The plant has been grown without any pruning or chemical treatment.

BOTANICAL DESCRIPTION OF THE NEW VARIETY

The following is a detailed botanical description of the new variety ‘LFKULI19’. Data was collected from three year old plants which had been grown in five gallon containers out of doors in Santa Barbara, Calif. The color determinations are in accordance with the fifth edition (2007) of The Royal Horticultural Society Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used. The plant has been grown without pruning or the use of growth-regulating chemicals.

COMPARISON WITH PARENT

Whereas the parent plant, the cultivar K. ericoides ‘Little Fox’ grows as a large mounding shrub to 1.2 m high×1.5 m wide, with medium coarse foliage, ‘LFKULI19’ grows as a lightly mounding, ground cover shrub with very fine and soft weeping foliage.
