plant named ‘TSF 004’

Abstract

A new and distinct Dipladenia cultivar named ‘TSF 004’ is disclosed, characterized by orange-red to red flowers and variegated foliage which has been proven stable. 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 004’.

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 Dipladenia sanderi ‘Cerise’ U.S. Plant Pat. No. 9,118. The selection was made among a group of the parent plants growing in a hoophouse at a commercial nursery Mar. 1, 2020 in Escondido, California.

Asexual reproduction of the new cultivar ‘TSF 004’ 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 004.’ These characteristics in combination distinguish ‘TSF 004’ as a new and distinct Dipladenia cultivar:

• • 1. Orange-red to red colored flowers.
  • 2. Cream colored variegated margins of foliage.
  • 3. Stability of variegation in successive vegetative propagation.

PARENT COMPARISON

Plants of the new cultivar ‘TSF 004’ 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 004’ can be compared to compared to the commercial variety Dipladenia Mandevilla ‘Monproud’, U.S. Plant Pat. No. 15,359. Plants of ‘Monproud’ are similar to plants of ‘TSF 004’ in most horticultural characteristics, however, plants of ‘TSF 004’ differ in the following:

• • 1. Flower color of ‘TSF 004’ is orange-red and red; flower color of this comparator is red-purple with some white streaks.
  • 2. Average flower size of the new variety is 6.5 cm in diameter and 7.5 cm in length; average flower size of this comparator is 5.5 cm in diameter and 6 cm in length.

‘TSF 004’ can aldo be compared to compared to the commercial variety Mandevilla ‘FGDIPIRV’, U.S. Plant Pat. No. 23,293. Plants of ‘FGDIPIRV’ are similar to plants of ‘TSF 004’ in most horticultural characteristics, however, plants of ‘TSF 004’ differ in the following:

• • 1. Average flower length of the new variety is 7.5 cm; average flower length of this comparator is 5 to 6 cm.
  • 2. Mature flower color of the new variety is Orange-Red N34A flushed Red 53A with no distinct venation coloration in petals; mature flower color of this comparator is varying shades of Red 53A, 53B, 46A and 46B with dull orange-red venation.
  • 3. Height of the new variety at 10 months is 35 cm; height of this comparator at 8 months is 96 cm.
