Abstract

A new and distinct Thunbergia plant named ‘Lemon Star’, characterized by its bright yellow flowers, dark green leaves, good basal branching character and climbing, spreading growth habit.

Description

Latin name of the genus and species of plant claimed: Thunbergia alata.
Variety denomination: ‘Lemon Star’.
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct Thunbergia plant, botanically known as Thunbergia alata, and hereinafter referred to by the cultivar name ‘Lemon Star’.
The new Thunbergia resulted from an induced chemical mutation of the seed variety Thunbergia alata (not patented). The ‘Lemon Star’ cultivar was discovered and selected by the inventor in 1999, at Rheinfelden, Germany. ‘Lemon Star’ is vegetatively reproduced rather than produced from seed, is more vigorous and has darker flower color than the parent.
Asexual reproduction of the new cultivar by terminal tip cuttings 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 yellow flowers;
(b) forms dark green foliage;
(c) exhibits a good branching character; and
(d) exhibits a vigorous climbing and trailing growth habit.
The new cultivar of the present invention can be compared to ‘Susie Yellow’ (not patented). In side by side comparisons, plants of the new cultivar exhibit a more vigorous growth habit, larger leaves and brighter yellow flowers than those of ‘Susie Yellow’.
BREIF DESCRIPTION OF PHOTOGRAPH
The accompanying photographs show 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 14 weeks in a greenhouse at West Chicago, Ill.
FIG. 1 illustrates the general plant from and growth habit of ‘Lemon Star’.
FIG. 2 illustrates a close up of the flowers of ‘Lemon Star’.
DETAILED BOTANICAL DESCRIPTION
The new cultivar 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 Aug. 15, 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 poly carbonate covered greenhouse under conditions comparable to those used in commercial practice while utilizing a soilless growth medium. Temperatures of approximately 70° to 80° F. (21° to 26° C.) during the day and approximately 60° to 65° F. (15° to 18° C.) during the night and light levels between 5,000 and 8,000 were maintained. Plants used for the following descriptions and measurements were grown for 14 weeks from rooted cuttings.

Throat texture: Upper ¼ is pubescent, rest is smooth. Throat color: 187B. Color of outer surface of corolla tube is 11C near opening and 79C at base.
Calyx.—Approximately 5 mm in length. The outer surface is densely pubescent and 149D.
Bracts.—Number: Approximately 10. Length: Approximately 2.9 cm. Width: Approximately 1.7 cm. Color: 145B with venation of 187A.
