USPP34217P2 - Myrtus plant named ‘Faz-Red’ - Google Patents

Abstract

A new and distinct variety of Myrtus plant named ‘FAZ-RED’ is disclosed, characterized by bright green, aromatic foliage, abundant flowering, and a round plant habit. Foliage also exhibits a strong red coloration during several months of the year. Plants are observed to tolerate a temperature range between −7° C. and 40° C. The new variety is a Myrtus, normally used for outdoor ornamental purposes.

Description

Latin name of the genus and species: Myrtus communis.

Variety denomination: ‘FAZ-RED’.

BACKGROUND OF THE INVENTION

The new cultivar was discovered as a naturally occurring branch mutation on an unnamed, unpatented Myrtus communis plant at a commercial nursery in Bitetto, Italy.

The parent is an unnamed variety of Myrtus communis. Myrtus ‘FAZ-RED’ was found and selected as a potential new variety by the inventor at the same nursery in Bitetto, Italy, in July 2014.

Asexual reproduction of the new cultivar has been performed by vegetative cuttings. This was first performed at a commercial nursery in Bitetto, Italy, in 2014, and has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘FAZ-RED’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘FAZ-RED’ These characteristics in combination distinguish ‘FAZ-RED’ as a new and distinct Myrtus cultivar:

• • 1. Persistent bright green leaves.
  • 2. Small leaves.
  • 3. Dark, brilliant red apical vegetation, persisting from November to March.
  • 4. Increased tolerance to cold and heat.
  • 5. Observed increased resistance to disease.
  • 6. Round plant habit.
  • 7. Abundant flowering.
  • 8. Aromatic leaves.

PARENT COMPARISON

Plants of the new cultivar ‘FAZ-RED’ are comparable to the unnamed parent variety of Myrtus communis. The two Myrtus varieties are similar in most horticultural characteristics; however, the new variety ‘FAZ-RED’ differs in the following:

• • 1. Foliage of ‘FAZ-RED’ is a more brilliant green than the parent.
  • 2. ‘FAZ-RED’ has a rounder growth habit than the parent.
  • 3. Foliage of ‘FAZ-RED’ retains its foliage and green foliage color after flowering, while foliage of the seed parent is prone to yellowing and falling after flowering.
  • 4. ‘FAZ-RED’ has a longer internode than the seed parent.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘FAZ-RED’ are comparable to the unpatented commercial variety Myrtus communis ‘Tarentina’. The two Myrtus varieties are similar in most horticultural characteristics; however, the new variety ‘FAZ-RED’ differs in the following:

• • 1. The new variety has foliage colored red for several months of the year, this comparator has green foliage throughout the year.
  • 2. The new variety has a smaller, rounder plant shape than this comparator.

Plants of the new cultivar ‘FAZ-RED’ are comparable to the unpatented commercial variety Myrtus communis ‘Nana’. The two Myrtus varieties are similar in most horticultural characteristics; however, the new variety ‘FAZ-RED’ differs in the following:

• • 1. The new variety has foliage colored red for several months of the year, this comparator has green foliage throughout the year.
  • 2. The new variety tolerates lower temperatures than this comparator.
