Abstract

A new Mimulus plant named ‘Minredda’ particularly distinguished by the large, bold red flowers, medium yellow-green foliage that is relatively non-sticky when compared to most other Mimulus varieties commercially available with upright and tiered plant habit.

Description

Latin name of the genus and species of the plant claimed: Mimulus aurantiacus.

Varietal denomination: ‘Minredda’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Mimulus, botanically known as Mimulus aurantiacus, and hereinafter referred to by the variety name ‘Minredda’.

‘Minredda’ is a product of a planned breeding program. The new cultivar has large, bold red flowers, darker yellow-green glossy foliage that is relatively non-sticky when compared to most other Mimulus varieties commercially available with upright and tiered plant habit.

‘Minredda’ originated from an open-pollinated hybridization made in July 2003 in Morgan Hill, Calif. The female parent was an unknown variety growing in a hobby garden. There are no known comparison statements to this female plant as the plant died before data was taken.

The male parent of ‘Minredda’ was an unknown variety. The resultant seed was sown in February 2004 in Gilroy, Calif. ‘Minredda’ was selected as one flowering plant within the progeny of the stated cross in the August 2004 in a controlled environment in Gilroy, Calif.

The first act of asexual reproduction of ‘Minredda’ was accomplished when vegetative cuttings were propagated from the initial selection in August 2004 in a controlled environment in Gilroy, Calif.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in August 2004, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Minredda’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Minredda’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar has been applied for in Canada on Feb. 9, 2010 (No. 10-6825). ‘Minredda’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Mimulus as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Minredda’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows a flowering plant of the new variety and a close-up of the flowers.

These photographs were taken in September 2009 of plants growing in a field trial in Gilroy, Calif.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken in late August 2010 under natural light. These plants were growing in field trials in Gilroy, Calif. These plants were about 20-22 weeks of age.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
