Abstract

A new and distinct Heuchera plant substantially as shown and described, characterized by yellow spring leaves, chartreuse leaves in summer, fall and winter, small, light coral pink colored flowers, and good vigor.

Description

Botanical denomination: Heuchera hybrida.
Variety designation: ‘Lemon Chiffon’.
Cross reference to siblings: Heuchera ‘Lime Rickey’ (U.S. Plant Pat. No. 16,210), and Heuchera ‘TNHEU042’ Key Lime Pie (U.S. Plant Pat. No. 16,735).
The present invention relates to a new and distinct cultivar of Heuchera hybrida and given the cultivar name of ‘Lemon Chiffon’. Heuchera is in the family Saxifragaceae. Heuchera ‘Lemon Chiffon’ originated from a cross between Heuchera ‘Amber Waves’ (U.S. Plant Pat. No. 13,348), as the seed parent, and Heuchera ‘Huntsman’, an unpatented plant, as the pollen parent. Given its ornamental foliage and flower form it is probable that Heuchera micrantha, H. americana, H. brizoides, and H. sanguinea are in its parentage.
This new Heuchera is distinguished by:
    • 1. Yellow spring leaves.
    • 2. Chartreuse leaves in summer, fall, and winter.
    • 3. Small light coral pink colored flowers.
    • 4. Good 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.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows the bloom and summer through winter foliage of Heuchera ‘Lemon Chiffon’.
FIG. 2 shows a one year old plant of Heuchera ‘Lemon Chiffon’ growing in the ground in the shade house in May in Canby, Oreg.

COMPARISON TO SIMILAR HEUCHERA
Compared to its sibling, Heuchera ‘Lime Rickey’ (U.S. Plant Pat. No. 16,210), this new variety has spring foliage that is yellow maturing to chartreuse rather than chartreuse spring foliage maturing to lime colored, light pink flowers rather than white, and leaves that are not ruffled, rather than ruffled.
Compared to its sibling, Heuchera ‘TNHEU042’ Key Lime Pie (U.S. Plant Pat. No. 16,735)), this new variety has spring growth that is yellow maturing to chartreuse rather than chartreuse spring foliage maturing to lime colored.
