Tiarella plant named ‘Jeepers Creepers’

Abstract

A new and distinct hybrid of Tiarella plant characterized by its unique creeping habit with good vigor, fine leaf form and coloration, and showy white flowers.

Description

The present invention relates to a new and distinct hybrid of Tiarella, of the family Saxifragaceae, which originated from a cross between unknown parents. This new Tiarella was one of many seedlings grown from select plants that were mass pollinated in the greenhouse in Canby, Oreg. Due to the fact that there were several different species involved, no species designations are given.

What makes this plant unique is its slow creeping habit. Tiarella normally is either clumping or running to five or more feet a year. Tiarella ‘Jeepers Creepers’ spreads 4 to 12 inches a year. It also has good quality foliage, vigor, and good flower size and number of flowers.

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. 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. 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.

COMPARISON TO OTHER PLANTS

Tiarella ‘Jeepers Creepers’ is unique from other Tiarella in having a creeping habit rather than running or clumping habit. This character, along with good vigor, foliage, and flowers made the instant plant stand out from all others. The breeder knows of no other Tiarella plant with all these characteristics.

Claims
