USPP36154P2 - Zamioculcas plant named ‘King’ - Google Patents

Abstract

A new and distinct cultivar of Zamioculcas plant named ‘KING’ is disclosed, characterized by fast-growing plants with large leaves placed at almost 90° to the stem. The new variety is a Zamioculcas, typically produced as an indoor ornamental plant.

Description

Latin name of the genus and species: Zamioculcas zamiifolia.

Variety denomination: ‘KING’.

BACKGROUND OF THE INVENTION

The new Zamioculcas ‘King’ is a naturally-occurring branch mutation from an unnamed, unpatented selection of Zamioculcas zamiifolia. The new Zamioculcas was discovered and selected by the inventor at a nursery in Erica, the Netherlands in the year 2021.

Asexual reproduction of the new cultivar by vegetative cuttings was first performed in May of 2022 in Erica, the Netherlands, and has shown Zamioculcas ‘King’ to be stable and true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘KING’ 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 ‘KING’. These characteristics in combination distinguish ‘KING’ as a new and distinct Zamioculcas cultivar:

• • 1. Leaves are occur at a novel angle, almost 90° angle to the stem, giving the plant a completely different look than the species itself.
  • 2. Plants of the new cultivar grow much quicker than the species itself.
  • 3. Large leaves.
  • 4. Plants make more shoots per leaf-cutting.

PARENT COMPARISON

Plants of the new cultivar ‘KING’ are similar to the parent, an unpatented, unnamed, Zamioculcas zamiifolia in most horticultural characteristics. However, the new variety, ‘KING’ differs from the parent in the following characteristics:

• • 1. Leaves of the new variety are placed at almost a 90° angle to the stem, while leaves of the parent variety are placed more upwards, at an angle of 40° to 60°.
  • 2. Leaves of the new variety are larger than leaves of the parent.
  • 3. Leaves of the new variety are long, elongated, with a pointed end. Leaves of the parent are shorter, less elongated, with a more rounded end.
  • 4. Plants of the new variety produce many more shoots than plants of the parent variety.

COMMERCIAL COMPARISON

Zamioculcas zamiifolia ‘KING’ can be compared with the commercial variety Zamioculcas zamiifolia ‘HANSOTI13’, U.S. Plant Pat. No. 26,760. The two varieties are similar in most horticultural characteristics; however, the new variety differs in the following:

• • 1. Leaves of the new variety are placed at almost a 90° angle to the stem, while leaves of this comparator are placed more upwards, at an angle of 40° to 60°.
  • 2. Leaves of the new variety are larger than leaves of this comparator.
  • 3. Leaves of the new variety are long, elongated, with a pointed end. Leaves of this comparator are shorter, less elongated, with a more rounded end.
  • 4. Plants of the new variety produce many more shoots than plants of this comparator.

Zamioculcas zamiifolia ‘KING’ can be compared with the commercial variety Zamioculcas zamiifolia ‘Dowon’ U.S. Plant Pat. No. 30,035. The two varieties are similar in most horticultural characteristics; however, the new variety differs in the following:

• • 1. Leaf color of the new variety is green to dark green, while leaf color of this comparator is dark purple.
  • 2. Leaves of the new variety are placed at almost a 90° angle to the stem, while leaves of this comparator are placed more upwards, at an angle of 40° to 60°.
  • 3. Leaves of the new variety are larger than leaves of this comparator.
  • 4. Leaves of the new variety are long, elongated, with a pointed end. Leaves of this comparator are shorter, less elongated, with a more rounded end.
  • 5. Plants of the new variety produce many more shoots than plants of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of the new Zamioculcas 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 Zamioculcas.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants of the new Zamioculcas grown in Erica, the Netherlands, in a greenhouse.
