| Abstract: |
A new and distinct hybrid of Heuchera characterized by unique, ruffled leaves of chocolate coloration showing the burgundy underside through the ruffles. |
| Claim: |
I claim:
1. A new and distinct hybrid of Heuchera substantially as shown and described, characterized by unique, ruffled leaves of chocolate coloration showing the burgundy underside through theruffles. |
| Description: |
The present invention relates to a new and distinct hyrbid of Heuchera which originated as a cross-pollination of Heuchera "Pewter Veil" and Heuchera micrantha "Ruffles" in theSaxifragaceae family.
The new Heuchera is a result of a controlled cross of the aforementioned plants at a Terra-Nova Nursery, Inc., in Portland, Oreg. This hybrid was selected from a large selection of seedlings. Mother plants were retained to observe habit and tocompare with their progeny. The new variety has been reproduced only be asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant and is unlike any Heuchera offered by any Americannursery or book as evidenced by the following characteristics:
(1) Summer, fall and winter: Chocolate-Olive coloration on the ruffled foliage. Reverse shown.
(2) Spring: Foliage of a warm Chocolate Brown on ruffled foliage with a Burgundy reverse.
Asexual propagation by division and tissue-culture as done in Mt. Vernon, Wash., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

Flowers: White, recurved calyx, Yellow-Green Group 145D on paniculate stems of Red-Purple Group 71A. Flowers may number several hundred per stem.
DESCRIPTION OF PARENT PLANTS
This Heuchera hybrid has characteristics which make it unique from its parents: Heuchera "Pewter Veil" and Heuchera micrantha "Ruffles". Heuchera micrantha "Ruffles" is described in the Terra-Nova Nursry's catalog as having heavily ruffled,hirsute foliage and white panicles of flowers. Heuchera "Pewter Veil" is described in the same catalog as a cross between Heuchera "Montrose Ruby" and Heuchera americana "Dale's Strain". The ensuing plants have pink/bronze-metallic leaves withpronounced veining. No other Heuchera in commerce resembles Heuchera "Chocolate Ruffles".
