USPP37235P2 - Adiantum plant named ‘TASSELS’ - Google Patents

Abstract

A new and distinct Adiantum cultivar named ‘TASSELS’ is disclosed, characterized by unique clusters of pinnae forming at terminus of fronds on mature plants, creating a different ornamental appearance due this this distinct morphology. Fronds are pendulous, large and composed of large pinnae. Plants of the new variety have been observed to recover rapidly and entirely from die back caused by drought. The new variety is a Adiantum, typically produced as an ornamental plant.

Description

Latin name of the genus and species: Adiantum hybrida.

Variety denomination: ‘TASSELS’.

BACKGROUND OF THE INVENTION

The new cultivar Adiantum ‘TASSELS’ was discovered by the inventor as a chance seedling growing among a plant collection of various Adiantum species in the inventor's home greenhouse in Henderson, Auckland, New Zealand. The exact parentage cannot be identified. The inventor is a collector of ferns and first identified the interesting seedling growing under a bench in her home greenhouse in 1985.

‘TASSELS’ was first asexually reproduced by the inventor at this home greenhouse in Henderson, Auckland, New Zealand. and has been found to retain its distinctive characteristics through 5 generations of asexual propagation.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the new cultivar when grown under normal horticultural practices:

• • 1. Unique clusters of pinnae forming at terminus of fronds on mature plants, creating a different ornamental appearance due to this distinct morphology.
  • 2. Large pinnae.
  • 3. Pendulous fronds.
  • 4. Large bipinnate fronds.

COMPARISON WITH PARENT VARIETIES

The seed and pollen parents are unknown.

COMPARISON WITH COMMERCIAL CULTIVARS

‘TASSELS’ can be compared to the unnamed, unpatented species Adiantum excisum. Plants are similar in most horticultural characteristics, however, ‘TASSELS’ differs in the following:

• • 1. The new variety forms pendulous fronds; this comparator forms horizontal or arching fronds.
  • 2. The new variety forms clusters of pinnae on terminal ends of fronds of mature plants. This comparator has fronds composed of evenly distributed pinnae.

‘TASSELS’ can be compared to the unnamed, unpatented species Adiantum fragrans. Plants are similar in most horticultural characteristics, however, ‘TASSELS’ differs in the following:

• • 1. The new variety forms pendulous fronds; this comparator forms horizontal fronds.
  • 2. The new variety forms clusters of pinnae on terminal ends of fronds of mature plants. This comparator has flat fronds composed of evenly distributed pinnae on a horizontal plane.

‘TASSELS’ can be compared to the unnamed, unpatented species Adiantum capillus-veneris commonly available. Plants of the two varieties are similar in most horticultural characteristics, however, ‘TASSELS’ differs in the following:

• • 1. Fronds of the new variety are larger than fronds of this comparator.
  • 2. Pinnae of the new variety are larger than fronds of this comparator.
  • 3. The new variety forms clusters of pinnae on terminal ends of fronds of mature plants.
  • 4. The new variety forms pendulous fronds; this comparator forms arching fronds.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The present invention of a new and distinct variety of Adiantum is shown in the accompanying photographs, the colors being as nearly true as possible with color photographs of this type.

FIG. 1 illustrates a plant of approximately 24 months from a division.

FIG. 2 illustrates a close up of the frond, including the clustered terminal pinnae.
