Latest Terra Nova Nurseries, Inc. Patents:
The present invention relates to a new and distinct intergeneric hybrid of Heuchera and Tiarella, of the family Saxifragaceae. It originated as a cross between an unpatented, unnamed Heuchera hybrid seedling (seed parent) and a plant patent applied for Tiarella named ‘Spring Symphony’ (pollen parent) (U.S. patent application Ser. No. 09/324,624). Due to the fact that the instant plant and parent plants are the result of crosses between two or more different Heuchera and/or Tiarella species, no species designations are given.
This new x Heucherella is a result of a controlled cross of the aforementioned plants of Terra Nova Nurseries, Inc., in Canby, Oreg. This hybrid was selected from a large selection of seedlings. Seed and pollen parent plants were retained to observe habit and to compare with the instant plant. 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.
This plant is characterized by the following:
1. Intense purplish-pink flowers.
2. Deeply lobed and dark centered foliage.
Asexual propagation by division and tissue culture as done by Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

DESCRIPTION OF PARENT PLANTS
The instant plant resulted from a cross between a Heuchera hybrid seedling and Tiarella ‘Spring Symphony’ PPAF. The Heuchera hybrid seedling was selected as a parent plant for its large pink flowers and strong silver-mottled leaves. The instant plant differs from the Heuchera hybrid seedling in having larger, brighter flowers, palmately parted, dark-centered leaves, and leaf veiling is not obvious. Tiarella ‘Spring Symphony’ was selected for its intense pink flowers and well-marked compact foliage. The instant plant differs from Tiarella ‘Spring Symphony’ in having intense mauve-pink flowers, broader lobes, dentate-crenate margins, and larger flower size.
