Maurandya plant named ‘Magic Dragon’

Abstract

A new cultivar of Maurandya named ‘Magic Dragon’ that is characterized by semi-weeping branches and light green foliage, large bright red trumpet-shaped flowers with flared lobes, and a climbing habit when secured to a stake or trellis. In combination these traits set ‘Magic Dragon’ apart from all other existing varieties of Maurandya.

Description

BOTANICAL CLASSIFICATION

Maurandya hybrid.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Twining Snapdragon known botanically as Maurandya and referred to hereinafter by the cultivar name ‘Magic Dragon’. The present invention was selected by the inventor in July 1995 in Newton Abbot, United Kingdom. The new invention is the product of the inventors breeding program. The purpose of the program was to produce a plant that will exhibit a climbing habit, while producing the bright red flowers of ‘Red Dragon’ and the larger flared trumpet flowers of Maurandya erubescens.

‘Magic Dragon’ is a hybrid that resulted from the induced hybridization of the female parent Maurandya ‘Red Dragon’ (not patented) and the male parent Maurandya erubescens (not patented). Correct nomenclature listed in The Royal Horticultural Society Dictionary of Gardening for Maurandya ‘Red Dragon’ includes the synonym Asarina ‘Red Dragon’ and correct nomenclature for Maurandya erubescens includes the synonym Asarina lophospermum.

‘Magic Dragon’ is distinguished by light green foliage, increased vigor over the parent plants, a climbing habit when secured to a stake or trellis, and large bright red, trumpet-shaped flowers with flared lobes. The closest comparison plants are the parents. ‘Magic Dragon’ differs from ‘Red Dragon’ in its climbing habit when secured and larger flared trumpet flowers. ‘Magic Dragon’ is distinguishable from Maurandya erubescens by the bright red color of its flowers.

‘Magic Dragon’ was first asexually propagated by the inventor in Newton Abbot, England in June 1996. Asexual propagation was accomplished using vegetative tip cuttings. Since that time, under careful observation, successive generations have been determined fixed, stable and uniform.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Maurandya cultivar ‘Magic Dragon’. In combination these traits set ‘Magic Dragon’ apart from all other existing varieties of Maurandya. ‘Magic Dragon’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

1. Maurandya ‘Magic Dragon’ exhibits semi-weeping branches and light green foliage.

2. Maurandya ‘Magic Dragon’ exhibits large, flared, bright red trumpet-shaped flowers.

3. Maurandya ‘Magic Dragon’ exhibits a climbing habit when secured to a stake or trellis.

4. Maurandya ‘Magic Dragon’ is 2 meters in height at maturity.

5. Maurandya ‘Magic Dragon’ is hardy to USDA Zone 9.

6. Maurandya ‘Magic Dragon’ blooms in spring and summer.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the distinguishing traits of ‘Magic Dragon’. The plants in the photographs are ten months old and were grown outside in fifteen-gallon containers.

The photograph on sheet 1 illustrates an entire specimen of ‘Magic Dragon’ in bloom from a side perspective.

The photograph on sheet 2 is a close-up photograph illustrating the flower and leaf. All photographs are taken using conventional techniques and although foliage colors may appear different from actual colors due to light reflectance, they are as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the Maurandya cultivar named ‘Magic Dragon’. Data was collected in Arroyo Grande, Calif. from ten month old plants grown outside in five-gallon containers. Color determinations are in accordance with The Royal Horticultural Society Colour Chart except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species and no disease problems have been observed.
