Botanical denomination: Heucherella hybrid.
Variety designation: ‘Brass Lantern’.
Cross reference to Heucherella ‘Sweet Tea’ (U.S. Plant Pat. No. 21,296).
The present invention relates to a new and distinct cultivar of Heucherella and given the cultivar name of ‘Brass Lantern’. Heucherella is in the family Saxifragaceae. Heucherella ‘Brass Lantern’ originated from a controlled cross between Heuchera ‘V3’ (a proprietary unreleased Heuchera villosa hybrid), as the seed parent, and massed selected Tiarella, as the pollen parent. The offspring were extremely variable and interesting. This is the third selected variety.
Compared to the seed parent, Heuchera ‘V3’ (unpatented), the new variety has leaves that are deeply lobed rather than shallowly lobed and more orange in color with a red center along the vein compared to no blotch.
Compared to the pollen parent, one of a Tiarella mass, the new variety has brassy gold and red foliage in spring rather than green.
Compared to Heucherella ‘Sweet Tea’ (U.S. Plant Pat. No. 21,296), the new variety has glossy leaves rather than a matte finish and gold with red centered spring leaves rather than bright rose orange with maroon centers.
This new Heucherella is unique in its coloration. There are no other varieties of this coloration known to the breeder. It is distinguished by:
-
- 1. brassy gold and red spring leaves,
- 2. glossy leaves,
- 3. olive green and brown summer leaves,
- 4. large, distinctive, palmately lobed leaves,
- 5. large plant size,
- 6. and excellent vigor.
This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.
The following is a detailed description of the new Heucherella cultivar based on observations of two-year-old specimens growing outside in the ground in the trial field in Canby, Oreg. Canby is Zone 8 on the USDA Hardiness map. Temperatures range from a high of 95 degrees F. in August to an average of 32 degrees F. in January. Normal rainfall in Canby is 42.8 inches per year. The color descriptions are all based on The Royal Horticultural Society Colour Chart, 5th edition.
