plant named ‘MonHariklia’

Abstract

A new and distinct Jasmium cultivar named ‘MonHariklia’ is disclosed, characterized by a long flowering season from April through October, strong, upright plant habit and good branching. Flowers are pure white when mature, and open fully. The new cultivar is a Jasmium, suitable for ornamental garden purposes.

Description

Latin name of the genus and species: Jasmium sambac.

Variety denomination: ‘MONHARIKLIA’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a chance discovery in a backyard setting by the inventor. In June 1997, the inventor, Eugenia Tzioroa discovered an interesting whole plant, naturally occurring mutation. This interesting plant was found by the inventor in Volos, Greece, in a residential garden and transferred to her home in Matthews, N.C.

Plant material of the new variety has not been easily reproduced, with first asexual reproduction occurring in Visalia, Calif. during 2011. In the meanwhile the plants were carefully controlled and held in a confidential location, not accessible to the public. 2 additional generations have been reproduced since 2011, and have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘MonHariklia’ 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 ‘MonHariklia’ These characteristics in combination distinguish ‘MonHariklia’ as a new and distinct Jasmium cultivar:

• • 1. Strong, upright plant habit.
  • 2. Average of 5 main branches per plant, for plants approximately 3 years old.
  • 3. Flowers open fully.
  • 4. Mature flowers are pure white, fading to red-purple.
  • 5. Longer bloom season, typically April through October. Longer with warm weather.
  • 6. Terminal clusters with up to 8 flowers per inflorescence.

COMPARISON TO PARENT VARIETY

The true parent variety is unknown.

COMMERCIAL COMPARISON

‘MonHariklia’ is best compared to the commercial variety Jasmium sambac ‘Grand Duke’, unpatented. Plants of the new cultivar ‘MonHariklia’ are similar to plants of ‘Grand Duke’ in most horticultural characteristics, however, plants of the new cultivar ‘MonHariklia’ differ in the following:

• • 1. Plants of the new variety have a more upright plant habit. ‘Grand Duke’ plants are ungainly, nearly vining.
  • 2. Plant growth of the new variety is more controlled, compared to ‘Grand Duke’.
  • 3. Flowers of the new variety open fully, whereas flowers of ‘Grand Duke’ never fully open outwardly.
  • 4. Flowers of the new variety mature to pure White, whereas flowers of ‘Grand Duke’ remain Green-White.
