plant named ‘TRE RES 08’

Abstract

A new and distinct Solenostemon plant cultivar is disclosed, characterized by deeply lobed, unjulating leaves; a sun tolerant Solenostemon that exhibits four colors; a more uniform growth habit; and short internodes.

Description

Latin name of the genus and species: Solenostemon scutellarioides.

Variety denomination: ‘TRI RES 08’.

BACKGROUND OF THE INVENTION

The new cultivar ‘TRI RES 08’ is a product of a natural mutation. The new cultivar was discovered and selected by Leroy and Jackie Griffard in April 2004 in Ste. Genevieve, Mo. The new cultivar was discovered in a greenhouse in a group of other Solenostemon plants but exhibited different leaf coloring and growing characteristics. The exact parent plant is unknown.

Asexual reproduction of the new cultivar ‘TRI RES 08’ by terminal cuttings was performed in Ste. Genevieve, Mo. and Oxnard, Calif., and has shown that the unique features of this new cultivar are stable and reproduced true to type on successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘TRI RES 08’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘TRI RES 08’. These characteristics in combination distinguish ‘TRI RES 08’ as a new and distinct Solenostemon cultivar:

• • 1. Deeply lobed, unjulating leaves;
  • 2. A sun tolerant Solenostemon that exhibits four colors;
  • 3. A more uniform growth habit; and
  • 4. Short internodes.

In comparison to the commercially available variety ‘Touch of Class’ (U.S. Plant Pat. No. 14,392), ‘TRI RES 08’ is more compact in both height and plant spread. Additionally, the foliage of the new variety ‘TRI RES 08’ are a darker green and a darker red than the green and red in the foliage of ‘Touch of Class’. Further, the markings on the foliage of the new variety ‘TRI RES 08’ are different in shape than ‘Touch of Class.’

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘TRI RES 08’ grown in a four-inch pot. One cutting was used in the pot, planted mid December and grown in a greenhouse. During the production of the plants, day temperatures were about 25° C., night temperatures were about 12° C. and light levels ranged from 4,000 to 6,000 footcandles. The colors are as nearly true as is reasonably possible in a color representation of this type.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘TRI RES 08’ plants grown in Oxnard, Ventura County, Calif., during the months of December through February. The growing temperature ranged from 12° C. to 15° C. at night to 12° C. to 20° C. during the day. Measurements and numerical values represent averages of typical Solenostemon plants.
