ABSTRACT:
CROSS-REFERENCE TO RELATED APPLICATIONS
The present invention is hereby cross-referenced to the three related claimed inventions entitled Heuchera ‘Canyon Duet’ (Ser. No. 09/203,861), Heuchera ‘Canyon Melody’ (Ser. No. 09/203,863), and Heuchera ‘Canyon Chimes’ (Ser. No. 09/203,864) which all four together resulted from the same breeding program as herein described.
BACKGROUND TO THE INVENTION
This new cultivar of Heuchera is the result of a long-term, controlled breeding program that was conducted by Dara Emery, Plant Breeder at the Santa Barbara Botanic Garden (SBBG), from the early 1980s until his death in 1992. ‘Canyon Belle’ is an F2 hybrid of
Heuchera elegans
(unpatented) and a hybrid form of
Heuchera sanguinea
(unpatented). It is unascertainable which parent—
Heuchera elegans
or a hybrid form of
Heuchera sanguinea —
is the seed or pollen parent. The objective of this breeding program was to select for compact, floriferous forms of Heuchera that were more diminutive than other forms in the nursery trade. Plants that exhibited an overall dwarf stature of low-growing, mounding foliage and flowers that are similarly proportioned were selected from the various crosses made. At least one of the parents had to be a native California species, in keeping with the overall mission of SBBG's breeding program to develop garden-worthy plants from the state's native flora. In this case,
H. elegans
is the California native; it has white-pink flowers and was used for its compact size.
Heuchera sanguinea
is an Arizonan species that is much larger in habit; it was used for its red flowers.
The closest comparison plants are the parent
Heuchera elegans
and the commercial cultivar Heuchera. ‘Canyon Delight’ (unpatented). ‘Canyon Belle’ is distinguishable from
Heuchera elegans
by its larger stature, larger foliage, taller flower stalks and flower color. ‘Canyon Belle’ is distinguishable from Heuchera ‘Canyon Delight’ by its smaller foliage; glossier leaf texture and flower color.
The cultivar was first and subsequently asexually reproduced by the inventor at the Santa Barbara Botanic Garden in Santa Barbara, Calif. by vegetative cuttings. Tip cuttings 2 to 3 inches long were put in flats of medium grade perlite and placed in a lath house mist bed with bottom heat and intermittent mist of de-ionized water. All plants so obtained exhibited identical characteristics, which were true to the original plant.
A closely related cultivar is the variety Heuchera ‘Canyon Delight’ (unpatented), which was selected by the inventor at an earlier stage in the breeding program and introduced to commerce. It is referred to and described herein as a comparison variety but is not the subject of any claim.
SUMMARY OF THE INVENTION
The features that together distinguish this cultivar from other Heuchera cultivars are as follows:
1. Dark glossy green leaves.
2. Compact habit.
3. Rich red flowers.
