Mimulus plant named ‘Jelly Bean Yellow’

Abstract

A distinct cultivar of Mimulus plant named ‘Jelly Bean Yellow’, characterized by its upright, somewhat spreading, mounding and compact plant habit; freely branching habit; moderate to high vigor; and numerous golden yellow flowers.

Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Mimulus plant, botanically known as Mimulus aurantiacus, and hereinafter referred to by the cultivar name Jelly Bean Yellow.

The new Mimulus is a product of a planned breeding program conducted by the Inventor in Alameda, Calif. The new Mimulus originated from a cross made by the Inventor of two unidentified selections of Mimulus aurantiacus. The new Mimulus was selected in 1998 on the basis of its compact and freely flowering habit.

Asexual reproduction of the new cultivar by terminal cuttings taken at Alameda, Calif., has shown that the unique features of this new Mimulus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Jelly Bean Yellow have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and nutritional status without, however, any variance in genotype.

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

1. Upright, somewhat spreading, mounding and compact plant habit.

2. Freely branching habit.

3. Moderate to high vigor.

4. Numerous golden yellow flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Mimulus.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Jelly Bean Yellow’ grown in a 15-cm container.

The photograph at the top of the second sheet is a close-up view of typical flowering stems of ‘Jelly Bean Yellow’.

The photograph at the bottom of the second sheet is a close-up view of typical flowers and the upper and lower surfaces of typical leaves of ‘Jelly Bean Yellow’.

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. Plants grown in 15-cm containers were used for the following description with one plant per container. Plants were grown in polyethylene-covered greenhouses and under conditions which closely approximate commercial production conditions during the spring in Encinitas, Calif. Day temperatures averaged about 18° C., night temperatures averaged about 10° C., and light levels were about 5,000 to 6,000 foot-candles.
