Antirrhinum plant named ‘Balumhopi’

Abstract

A new and distinct Antirrhinum plant named ‘Balumhopi’, characterized by its bright pink flowers, mounded and trailing habit, and dark green leaves.

Description

LATIN NAME OF THE GENUS AND SPECIES OF PLANT CLAIMED

Anthirrhinum majus.

VARIETY DENOMINATION

‘Balumhopi’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct Antirrhinum plant, botanically known as Antirrhinum majus, and hereinafter referred to by the cultivar name ‘Balumhopi’. The new cultivar was developed by the inventor through a controlled breeding program during 1998 at Arroyo Grande, Calif. The objective of the breeding program was the development of Antirrhinum cultivars with mounded trailing habit, continuous flowering, excellent basal branching and small, dark green leaves.

The female (seed) parent of ‘Balumhopi’ was the proprietary Antirrhinum breeding selection designated 422-4, which exhibits an upright habit, yellow flowers and medium green foliage. The male (pollen) parent of ‘Balumhopi’ was the proprietary Antirrhinum breeding selection designated 427-3 which exhibits a semi-trailing habit, light pink flowers and medium green foliage. The new cultivar was discovered as a single flowering plant from within the progeny of the above stated cross in December 1999 and was initially designated 1195-1.

Asexual reproduction of the new cultivar has been carried out at Arroyo Grande, Calif. and West Chicago, Ill. by terminal tip cuttings and has demonstrated that the characteristics of the new cultivar as herein described are firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

It was found that the cultivar of the present invention:

(a) Exhibits bright pink flowers;

(b) Forms dark green foliage;

(c) Exhibits a good basal branching character; and

(d) Exhibits a trailing growth habit.

The new cultivar of the present invention can be compared to ‘Balumpink’ (co-pending U.S. Plant patent application Ser. No. 09/808,532). In side-by-side comparisons, the flowers of ‘Balumhopi’ are darker pink than those of ‘Balumpink’.

BRIEF DESCRIPTION OF PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. The plants were grown for 12 weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANICAL DESCRIPTION

The cultivar ‘Balumhopi’ has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length. The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England. The color values were determined on Apr. 18, 2001. The readings were taken between 1:00 and 3:00 p.m. under natural daylight conditions. The plants were produced from cuttings taken from stock plants and were grown in a double polycarbonate covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown utilizing a soilless growth medium with temperatures of approximately 65° to 75° F. (18° to 24° C.) during the day and approximately 50° to 55° F. (10° to 14° C.) during the night and light levels of 5,000 to 6,000 footcandles being maintained. Plants used for the following descriptions and measurements were grown in 10 cm pots for 12 weeks from rooted cuttings.
