Claims
I claim:
1. A new and distinct cultivar of Tiarella plant herein illustrated
and described.
Description
Botanical denomination: Tiarella hybrid.
Variety designation: `Sugar and Spice`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of a
hardy herbaceous perennial of the genus Tiarella, and known by the
cultivar name `Sugar and Spice`. The genus Tiarella is a member of
the family Saxifragaceae.
The new cultivar originated as a cross between unknown parents.
This new Tiarella was one of many seedlings grown from select
experimental and proprietary interspecific hybrids and species that
were mass pollinated in the greenhouse in Canby, Oreg. From
observation of the characteristics exhibited by the instant plant,
it is probable that Tiarella trifoliata var. laciniata and T.
wherryi are in its parentage.
SUMMARY OF THE INVENTION
This plant is characterized by the following: 1. Medium size. 2.
Mounding habit. 3. Pinnately divided leaves with a broad dark band
down each division. 4. Pink flower buds and white flower color. 5.
Excellent vigor.
The new variety has been reproduced only by asexual propagation
(division and micropropagation). Each of the progeny exhibits
identical characteristics to the original plant. Asexual
propagation by division and micropropagation using standard
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 DRAWING
The drawing shows a two-year-old Tiarella `Sugar and Spice` in
bloom grown outside in a one gallon container in the garden in
April in Canby, Oreg.
DETAILED PLANT DESCRIPTION
The following is a detailed description of the new Tiarella hybrid

COMPARISONS WITH SIMILAR TIARELLA
Compared with Tiarella `Neon Lights` (U.S. Plant Pat. No. 13,289),
Tiarella `Sugar and Spice` has similar leaf shape and size except
that `Neon Lights` has more secondary lobing. The leaves of `Sugar
and Spice` are darker with more olive tones on the mature leaves.
The flowers on this new cultivar are more numerous, pinker, and
have stronger, shorter stems.
