Description

Genus and species: Mussaenda hybrid.

Variety denomination: ‘Marmalade’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Mussaenda, botanically known as Mussaenda hybrid, and hereinafter referred to by the cultivar name ‘Marmalade’. The new cultivar originated from a hybridization made in December 1995 in Alipore, India. The female parent was the hot-pink-flowered Mussaenda philippica plant ‘Doña Luz’ (unpatented), while the male parent was a pale-yellow-flowered individual plant of Mussaenda luteola (unpatented). The seeds produced by the hybridization were sown in 1996 in Alipore, India and a single plant selection was chosen for further evaluation and for asexual propagation in 1998/1999 in Alipore, India.

The new cultivar was created in 1995 in Alipore, India and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Homestead, Florida over a two-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Homestead, Fla.

    • 1. Flowers are prominent, bright yellow with a yellow-orange eye which ages from orange to brown;
    • 2. Trapezoidal sepals range in color from bright yellow to orange to pink and red-purple;
    • 3. Sepals are pendulous and are occasionally twisted; and
    • 4. Can withstand brief periods of freezing temperatures without damage.

DESCRIPTION OF THE PHOTOGRAPHS

This new Mussaenda plant is illustrated by the accompanying photographs which show blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Marmalade’. The data which define these characteristics were collected from asexual reproductions carried out in Homestead, Fla. The plant history was taken on six-month-old plants grown in 10-gallon containers. Color readings were taken in under natural light. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001 edition).

COMPARISON WITH PARENTAL CULTIVARS

‘Marmalade’ differs from the female parent, ‘Doña Luz’ (unpatented) in that ‘Marmalade’ has sepals which emerge yellow especially when shaded and become orange in full sun and as they age, whereas ‘Doña Luz’ has sepals which emerge hot pink and stay the same color as they age. Additionally, ‘Marmalade’ has a prominent bright yellow-orange “eye” while ‘Doña Luz’ has a smaller, light yellow-orange “eye”. Finally, ‘Marmalade’ has sepals which are trapezoidal, pendulous and often twisting, whereas ‘Doña Luz’ has sepals which are oval, do not twist and are evenly uniform in shape.

‘Marmalade’ differs from the male parent, Mussaenda luteola (unpatented) in that ‘Marmalade’ has sepals which emerge yellow especially when shaded and become orange in full sun and as they age, whereas M. luteola has sepals which emerge pale yellow and stay the same color as they age. Additionally, ‘Marmalade’ has star-shaped flowers with a prominent yellow orange eye, whereas M. luteola has salver-shaped flowers with a small orange eye. Finally, ‘Marmalade’ has sepals which are trapezoidal, pendulous, often twisting and arranged haphazardly around each flower, whereas M. luteola has sepals which are pennant-shaped, numerous and arranged in a neat even cluster around each flower.
