plant named ‘TSF 003’

Abstract

A new and distinct Dipladenia cultivar named ‘TSF 003’ is disclosed, characterized by pink flowers and variegated foliage which has been proven stable. The variegated foliage has The new variety is a Dipladenia, typically produced as an indoor ornamental plant.

Description

Latin name of the genus and species: Dipladenia sanderi.

Variety denomination: ‘TSF 003’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of chance discovery. The new variety was discovered as a naturally occurring whole plant mutation of the unpatented Dipladenia sanderi ‘Red Riding Hood’, unpatented. The selection was made at a commercial nursery Mar. 1, 2020 in Escondido, California.

Asexual reproduction of the new cultivar ‘TSF 003’ was first performed at a commercial nursery in Escondido, California by terminal vegetative cuttings in April of 2020. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘TSF 003.’ These characteristics in combination distinguish ‘TSF 003’ as a new and distinct Dipladenia cultivar:

• 1. Pink flowers.
• 2. Cream colored variegated margins of foliage.
• 3. Stability of variegation in successive vegetative propagation.

PARENT COMPARISON

Plants of the new cultivar ‘TSF 003’ are similar to the seed parent in most horticultural characteristics. The new variety, however, differs in the following:

• 1. The new variety has variegated foliage; the parent variety has solid colored foliage.

COMMERCIAL COMPARISON

‘TSF 003’ can be compared to compared to the commercial variety Dipladenia ‘Madinia Pink’, unpatented. Plants of ‘Madinia Pink’ are similar to plants of ‘TSF 003’ in most horticultural characteristics, however, plants of ‘TSF 003’ differ in the following:

• • 1. 1. The new variety has variegated foliage; this comparator has solid colored foliage.
