USPP22093P2 - Heuchera plant named ‘Lipstick’ - Google Patents

Abstract

A new and distinct Heuchera plant substantially as shown and described, characterized by red flowers on repeat blooming spikes, medium small, bluish green leaves, a low mounding habit, and excellent vigor.

Description

Botanical denomination: Heuchera spp.

Variety designation: ‘Lipstick’.

The present invention relates to a new and distinct cultivar of Heuchera and given the cultivar name of ‘Lipstick’. Heuchera is in the family Saxifragaceae. Heuchera ‘Lipstick’ originated from a planned cross between Heuchera 542-1, a proprietary unreleased plant, as the seed parent, and Heuchera 465-1, a proprietary unreleased plant, as the pollen parent. Compared to the seed parent, Heuchera 542-1, the new cultivar has red rather than white flowers. Compared to the pollen parent, Heuchera 465-1, the new cultivar has flowers that are red rather than rose red.

Compared to Heuchera ‘Blood Red’ (U.S. Plant Pat. No. 17,153), the new cultivar is a larger plant, with larger leaves that are a bluer green when mature. The flowers of the new cultivar are smaller. The new cultivar is a repeat bloomer.

This new Heuchera is distinguished by:

• • 1. red flowers on repeat blooming spikes,
  • 2. medium small, bluish green leaves,
  • 3. a low mounding habit,
  • 4. and excellent vigor.

This new cultivar has been reproduced only by asexual propagation (cuttings and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by stem cuttings and tissue culture using 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.
