Abstract: A new and distinct cultivar of .times.Heucherella plant characterized by its distinctive golden to lime green foliage with a maroon blotch.
Claim: I claim:

1. A new and distinct cultivar of .times.Heucherella plant substantially as shown and described, characterized by its distinctive golden to lime green foliage with a maroon blotch.
Description: Botanical classification: .times.Heucherella sp.

Cultivar denomination: `Sunspot`.


The present invention relates to a new and distinct intergeneric hybrid between Heuchera and Tiarella, or .times.Heucherella, and given the cultivar name `Sunspot`. Both genera, Heuchera and Tiarella, are of the family Saxifragaceae.

This new cultivar originated from a mutation in tissue culture from .times.Heucherella `Dayglow Pink` (U.S. Plant Pat. No. 12,164).


This new Heucherella is unique in its golden to lime green foliage unique in the .times.Heucherella with a maroon starry blotch in the middle and characterized by: 1. Small, lobed leaves. 2. Intense pink flowers on maroon peduncles. 3. Tighthabit. 4. Excellent vigor.

The new variety 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 standardmicropropagation 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 inventionhas 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 drawing shows the two year old plant growing in a two-gallon pot in Canby, Oreg.
