Abstract

A new and distinct hybrid of Heuchera plant characterized by a unique combination of mint-green leaves with a pinkish-purple cast and compact form.

Description

The present invention relates to a new and distinct hybrid of Heuchera, of the family Saxifragaceae, which originated as a cross between an unpatented Heuchera named ‘French Velvet’ (seed parent) and an unpatented, unnamed Heuchera hybrid seedling (pollen parent). Due to the fact that the instant plant and parent plants are the result of crosses between several different Heuchera species, no species designations are given.
This new Heuchera is a result of a controlled cross of the aforementioned plants 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. Mint-green foliage with a pinkish-purple cast.
2. Compact form as a result of short petioles.
Asexual propagation by division and tissue culture as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.
BRIEF DESCRIPTION OF THE DRAWING
The drawing shows Heuchera ‘Autumn Haze’ in April in Canby, Oreg.

DESCRIPTION OF PARENT PLANTS
The instant plant resulted from a cross between Heuchera ‘French Velvet’ and an unnamed Heuchera hybrid seedling. Heuchera ‘French Velvet’ was selected as a parent plant for its felted leaves (underside and petioles) and foliage color. The instant plant differs from Heuchera ‘French Velvet’ in having substantially more silver veiling, shorter leaf hairs, and shorter petioles. The Heuchera hybrid seedling was selected for its silver veiling and compact form. The instant plant differs from the Heuchera hybrid seedling in having a sharper leaf appearance (margins are more dentate) and hairier petioles and leaf underside.
