plant named ‘Julietta’

Abstract

A new and distinct cultivar of Vriecantarea plant named ‘Julietta’, characterized by its upright and outwardly arching growth habit; glossy dark purple and green-colored leaves; and good interiorscape performance with plants maintaining good leaf color for about six months under moderate light levels.

Description

Botanical designation: Vriecantarea hybrida.

Cultivar denomination: ‘JULIETTA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Vriecantarea plant, botanically known as Vriecantarea hybrida, previously known as (Alcantarea imperialis×Vriesea polemanii)×Alcantarea vinacolor, and hereinafter referred to by the name ‘Julietta’.

The new Vriecantarea plant is a product of a planned breeding program conducted by the Inventor in Hilo, Hawaii. The objective of the breeding program is to create new Vriecantarea plants with uniquely colored leaves and good interiorscape performance.

The new Vriecantarea plant originated from a self-pollination made by the Inventor in 2009 in Hilo, Hi. of Vriecantarea hybrida ‘Volcano's Mist’, not patented. The new Vriecantarea plant was discovered and selected by the Inventor as a single plant within the progeny of the stated self-pollination in a controlled greenhouse environment in Hilo, Hi. in 2010.

Asexual reproduction of the new Vriecantarea plant by offsets and micro-propagation in a controlled environment in Hilo, Hi. since 2011 has shown that the unique features of this new Vriecantarea plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Vriecantarea have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

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

• • 1. Upright and outwardly arching growth habit.
  • 2. Glossy dark purple and green-colored leaves.
  • 3. Good interiorscape performance with plants maintaining good leaf color for about six months under moderate light levels.

Plants of the new Vriecantarea differ primarily from plants of the parent, ‘Volcano's Mist’, in the following characteristics:

• • 1. Leaves of plants of the new Vriecantarea are more intensely-colored than leaves of plants of ‘Volcano's Mist’.
  • 2. Leaves of plants of the new Vriecantarea have a thicker waxy cuticle than leaves of plants of ‘Volcano's Mist’.

Plants of the new Vriecantarea can be compared to plants of unnamed selections of Alcantarea imperialis known to the Inventor, not patented. In side-by-side comparisons conducted in Hilo, Hi., plants of the new Vriecantarea and the unnamed selections of Alcantarea imperialis differed primarily in the following characteristics:

• • 1. Leaves of plants of the new Vriecantarea were more intensely-colored than leaves of plants of the unnamed selections of Alcantarea imperialis.
  • 2. Leaves of plants of the new Vriecantarea had a thicker waxy cuticle than leaves of plants of the unnamed selections of Alcantarea imperialis.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Vriecantarea plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Vriecantarea plant.

The photograph at the bottom of the sheet is a side perspective view of a typical plant of ‘Julietta’ grown in a container.

The photograph at the top of the sheet is a top perspective view of a typical plant of ‘Julietta’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 15.25-cm containers in an outdoor nursery in Hilo, Hi. and under cultural practices typical of commercial Vriecantarea production. During the production of the plants, day temperatures ranged from 18° C. to 32° C., night temperatures ranged from 12° C. to 25° C. and light levels averaged 18,000 foot-candles. Plants were six months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
