Abstract

A new Mimulus plant named ‘Mimapri’ particularly distinguished by the large, orange-red flowers, glossy medium green foliage, with upright and tiered plant habit.

Description

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

Varietal denomination: ‘Mimapri’.

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 ‘Mimapri’.

‘Mimapri’ is a product of a planned breeding program. The new cultivar has large, orange-red flowers, glossy medium green foliage, with upright and tiered plant habit.

‘Mimapri’ originated from a hybridization made in July 2001 in a controlled breeding environment in Gilroy, Calif. The female parent was an unpatented, proprietary plant designated ‘CO126-1’ with yellow flowers, a more trailing habit and less branching.

The male parent of ‘Mimapri’ was an unpatented, proprietary plant identified as ‘CO134-1’ with pink flowers, larger flower size and lighter green foliage. The resultant seed was sown in February 2002.

‘Mimapri’ was selected as one flowering plant within the progeny of the stated cross in August 2002 in a controlled environment in Gilroy, Calif.

The first act of asexual reproduction of ‘Mimapri’ was accomplished when vegetative cuttings were propagated from the initial selection in August 2002 in a controlled environment in Gilroy, Calif.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in August 2002, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Mimapri’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Mimapri’ 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. 10-6824). ‘Mimapri’ 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 ‘Mimapri’ 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.
