USPP11390P - Heuchera plant named `Magic Wand` - Google Patents

Abstract

A new and distinct hybrid of Heuchera plant characterized by unique flower panicles, attractive leaf coloration, and large flowers.

Description

The present invention relates to a new and distinct hybrid of Heuchera in the Saxifrage family (Saxifragaceae) which originated as a cross-pollination of an unnamed, unpatented Heuchera hybrid seedling (female parent) and a selected unnamed, unpatented Heuchera sanguinea plant (male parent) showing brilliant coloration.

The new Heuchera is a result of a controlled cross of the aforementioned plants at Terra Nova Nursery, 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 new variety. 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 and is unlike any Heuchera offered by any American nursery or book known to me as evidenced by the following characteristics:

(1) Late summer, fall and winter: Attractive mottled foliage.

(2) Spring/Early summer: Colorful flowers on hirsute panicles.

Asexual propagation by division and tissue-culture as done in Tigard, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

Disease: Plants grown in Canby, Oreg., show little susceptibility to diseases except for root rot when grown under wet conditions.

Hardiness: Cold tolerance is set at USDA Zone 4 (-34° to -29° C.). Upper heat tolerance is unknown.

Color Characteristics

Foliage:

Mature leaves, upper surface, spring/summer.--R.H.S. 137A Green Group (Moderate Olive Green ARS) mottled with R.H.S. 148D Yellow Green Group (Grayish Yellow Green ARS).

Upper surface, fall through winter.--R.H.S. 139B Green Group (Moderate Yellowish Green ARS) mottled with R.H.S. 139D Green Group (Moderate Yellow Green ARS).

Lower surface.--R.H.S. 148D Yellow Green Group (Grayish Yellow Green ARS).

Flowers:

Petal upper surfaces.--R.H.S. Red Purple Group 57A (Vivid Red ARS) senescing to R.H.S. Red Purple Group 60A.

Petal lower surfaces.--R.H.S. Red Group 39B senescing to R.H.S. Red Purple Group 60A. Area around ovary: R.H.S. Red Group 36D.

Stamens: R.H.S. Orange Group 28A.

Peduncle: R.H.S. Yellow Green Group 146A becoming R.H.S. Red Purple Group 152A near the apex.

Fruit: R.H.S. Green Group 143B.

DESCRIPTION OF PARENT PLANTS

This hybrid has characteristics which make it unique from its parents. One parent was a Heuchera seedling selected for its large inflorescences and large flowers. However, flower color was poor. The other parent was a selected H. sanguinea seedling in the nursery with huge cerise flowers and attractively mottled foliage. Crossing of the aforementioned plants resulted in the instant cultivar displaying superior flower color, large flowers, dense inflorescences, and attractive mottled foliage. `Raspberry Regal` (unpatented) is the closest Heuchera to the instant cultivar in commerce known to me but suffers from muddy flower color and non-distinctive foliage. (See Aileen Stocks, Saxifragaceae, published by the Hardy Plant Society (ISBN 901687 111), p. 36.)

Claims (1)

I claim:
