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.

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.

 DESCRIPTION OF ENT 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.
