Abstract

A new and distinct hybrid of Tiarella characterized a distinct leaf form and coloration.

Description

Botanical classification: Tiarella hybrid.
Variety denomination: ‘Black Snowflake’.
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 ‘Black Snowflake’. 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 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 most likely an interspecific hybrid. As such no species designations are given.
SUMMARY OF THE INVENTION
This plant is characterized by the following:
1. Distinct, deeply palmately lobed leaves.
2. Striking, dark coloration on the leaf veins and continuing almost to the margins.
3. Slightly stoloniferous habit.
4. Early bloom time and good reblooming.
5. Excellent vigor.
6. Good winter color.
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 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 DRAWING
The FIGURE is of Tiarella ‘Black Snowflake’ still in bloom in a pot in July in Canby, Oreg.
DETAILED PLANT DESCRIPTION
The following is a detailed description of the new Tiarella hybrid based on observations of two-and-a-half-year-old plants grown in three-gallon pots in Canby, Oreg. The color descriptions are all based on The Royal Horticultural Society Colour Chart.

Leaf color.—The outside half of the leaf is deep green, Green 138A, with a dark maroon pattern of Greyed Purple 187A along the veins spreading about ¾ or more toward the margin. In winter the leaf edges are green, Green 137A and the rest is a black maroon color, between Black 202A and Greyed Purple 187A.
Inflorescence:
Type.—Raceme or panicle.
Flower number.—70 blooms per raceme and about 70 racemes blooming in the first flush, the racemes sometimes once to twice branching, extending the bloom time.
Bloom period.—April to May with sporadic rebloom throughout the summer and fall.
Peduncle.—With one or two green or green with dark-veined cauline leaves. Height — 42 cm. Width — 2.5 mm. at the widest point. Color — Yellow green 146B overall, darker at the base and the tip (Greyed Orange 177A). Texture — Hispid.
