plant named ‘TNGEUTR’

Abstract

A new and distinct Geum plant named ‘TNGEUTR’ characterized by medium large, semi-double flowers that are rose-red and fade to light pink, mounding habit, heavy spring bloom with repeat bloom throughout the summer, and excellent vigor.

Description

Botanical designation: Geum hybrid.

Variety denomination: ‘TNGEUTR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geum plant given the name ‘TNGEUTR’. Geum is in the family Rosaceae. The new cultivar was bred using unknown, unnamed proprietary plants. The new cultivar was selected for its superior habit and flowering.

Compared to Geum ‘Cosmopolitan’ (U.S. Plant Pat. No. 24,982) the new cultivar has more rose-red flower color, with more and shorter flowering stems. In addition, the new cultivar reblooms sporadically summer through fall rather than only spring blooming.

Compared to Geum ‘Mai Tai’ (U.S. Plant Pat. No. 22,433) the new cultivar is has more rose-red flower color rather than orange. In addition the new cultivar reblooms sporadically summer through fall rather than only spring blooming.

Compared to Geum ‘Cherry Bomb’ an unpatented cultivar, the new cultivar has a higher flower count and reblooms sporadically summer through fall rather than only spring blooming.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘TNGEUTR’. These characteristics in combination distinguish ‘TNGEUTR’ as a new and distinct cultivar:

• • 1. medium large flowers that are rose-red and fade to light pink,
  • 2. semi-double flowers,
  • 3. good flower size,
  • 4. heavy blooming,
  • 5. dense, deep green foliage with attractive leaves,
  • 6. a compact, mounding habit,
  • 7. heavy spring bloom with repeat bloom throughout the summer and fall, and
  • 8. excellent vigor.

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

The Trademark designation of the new cultivar is TEMPO™ Rose.
