1. A new and distinct cultivar of Heuchera plant named ‘Orange Dream’ as herein illustrated and described.
11. A new and distinct cultivar of Heuchera plant named ‘Orange Dream’ as herein illustrated and described.
Botanical classification: Heuchera hybrid.
Cultivar designation: ‘Orange Dream’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Heuchera of hybrid origin, botanically known as a Heuchera and is hereinafter referred to by its cultivar name ‘Orange Dream’.
The new cultivar was discovered as a chance seedling in a trial field by the Inventor in Hantay, France in May of 2014. The trial field contained hundreds of proprietary Heuchera seedlings from the Inventor's breeding program. The exact parentage of ‘Orange Dream’ is therefore unknown.
Asexual propagation of the new cultivar was first accomplished under the direction of the Inventor by in vitro propagation initiated from meristem tissue in Rijswijk, The Netherlands in June 2015. Asexual propagation of the new cultivar by in vitro propagation has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Orange Dream’ as a new and unique cultivar of Heuchera.
- 1. ‘Orange Dream’ exhibits a compact plant habit.
- 2. ‘Orange Dream’ exhibits leaves that are orange in color.
- 3. ‘Orange Dream’ exhibits flowers that are white in color.
‘Orange Dream’ can be most closely compared to the Heuchera cultivars ‘Vulcano’ (U.S. Plant Pat. No. 25,625) and ‘Apricot’ (U.S. Plant Pat. No. 27,139). Both are similar to ‘Orange Dream’ in having orange toned foliage. ‘Vulcano’ is also similar to ‘Orange Dream’ in foliage shape. ‘Vulcano’ differs from ‘Orange Dream’ in having leaves that are deeper orange in color. ‘Apricot’ differs from ‘Orange Dream’ in having leaf surfaces that are glossier, leaf-lobes that are round in shape, more numerous flowering stems, and flowers that are pink in color.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new Heuchera. The photograph was taken of a plant one year in age as grown in a greenhouse in a 27-cm container in Hantay, France.
The photograph in FIG. 1 provides a side view of the plant of ‘Orange Dream’ in bloom.
The photograph in FIG. 2 provides a close up of the inflorescence of ‘Orange Dream’.
The photograph in FIG. 3 provides a close up of the foliage of ‘Orange Dream’.
The colors in the photograph are as close as possible with the digital photography techniques available, the color values cited in the detailed botanical description accurately describe the colors of the new Heuchera.
DETAILED BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed description of 18 month-old plants of the new cultivar as grown outdoors in 27-cm containers in Hantay, France.
