‘DAPJUR02’

A new and distinct Daphne cultivar named ‘DAPJUR02’ is disclosed, characterized by an abundance of large, white, highly fragrant flowers. Plants are bushy and produce unique, unusually long racemes of flowers. Plants are sun tolerant. The new variety is a Daphne, normally produced as an outdoor garden or container plant.

Description

Latin name of the genus and species: Daphne odora.

Variety denomination: ‘DAPJUR02’.

BACKGROUND OF THE INVENTION

The new Daphne cultivar is a product of a chance discovery. The new variety was discovered as a naturally occurring whole plant mutation at a commercial nursery in Hope, New Zealand. The parent variety is Daphne odora ‘DAPJUR01’, U.S. Plant Pat. No. 27,662. The new variety was first identified in August of 2016.

Asexual reproduction of the new cultivar was performed by semi-softwood vegetative cuttings. This was first performed at a commercial nursery in North Taranaki, New Zealand in September of 2016. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in 2 successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘DAPJUR02’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DAPJUR02’ These characteristics in combination distinguish ‘DAPJUR02’ as a new and distinct Daphne cultivar:

  • 1. Large flowers.
  • 2. Unique flowering configuration, with flowers forming a spike like raceme, instead of a terminal cluster head of flowers, which is typical of Daphne.
  • 3. Highly fragrant flowers.
  • 4. Suitability for both container and garden plantings.
  • 5. Bushy plant habit.
  • 6. Sun tolerance.

PARENT COMPARISON

Plants of the new cultivar ‘DAPJUR02’ are similar to plants of the parent in most horticultural characteristics, however, plants of the new cultivar ‘DAPJUR02’ differ in the following;

  • 1. The new variety has a white flower, the parent variety has a Violet-Blue and Red-Purple flower.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘DAPJUR02’ are comparable to the unpatented commercial variety Daphne odora ‘Alba’. The two Daphne varieties are similar in most horticultural characteristics; however, the new variety ‘DAPJUR02’ differs in the following:

  • 1. The new variety has larger flowers.
  • 2. New variety has a lighter leaf color.
  • 3. The new variety is sun tolerant. The comparator is not known to be sun tolerant.
  • 4. The new variety has a longer flowering period.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘DAPJUR02’ grown in a nursery. FIG. 2 illustrates a close up of the inflorescence.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION
