plant named ‘LILLIPUT’

Abstract

A new and distinct Portulacaria cultivar named ‘LILLIPUT’ is disclosed, characterized by a diminutive overall stature, and small emerald green leaves. Plants are a size suitable for smaller gardens. The new variety is a Portulacaria, typically produced as a garden or container plant.

Description

Latin name of the genus and species: Portulacaria afra.

Variety denomination: ‘LILLIPUT’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a naturally occurring whole plant mutation in a commercial nursery in Vista, Calif. The parent is an unpatented, unnamed variety of Portulacaria afra. ‘LILLIPUT’ was found and selected by the inventor in Vista, Calif. in June 2013.

Asexual reproduction of the new cultivar ‘LILLIPUT’ was first performed by vegetative tip cuttings at a commercial greenhouse in Vista, Calif. in July 2013. ‘LILLIPUT’ has since produced at least 15 generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

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

• • 1. Small overall stature.
  • 2. Small leaves.
  • 3. Suitable for smaller gardens.

PARENTAL COMPARISON

Plants of the new cultivar ‘LILLIPUT’ are similar to the parent in most horticultural characteristics. However, plants of the new variety differ from the parent in the following:

• • 1. New variety exhibits a smaller stature than the parent.
  • 2. New variety displays a miniature appearance, due to smaller ramification and smaller leaves than the parent. The parent is standard sized.
  • 3. New variety is more suitable for small dish gardens than the parent.

COMMERCIAL COMPARISON

‘Lilliput’ can be compared to the unpatented commercial variety Portulacaria afra ‘Prostrata’. The two Portulacaria varieties are similar in most horticultural characteristics; however, the new variety differs in the following:

• • 1. New variety has smaller leaves than this comparator.
  • 2. New variety has an upright morphology, while the comparator has a more pendulous morphology.
  • 3. New variety is more suitable for small dish gardens than this comparator.

‘Lilliput’ can also be compared to the unpatented commercial variety Portulacaria afra ‘Variegta’. The two Portulacaria varieties are similar in most horticultural characteristics; however, the new variety differs in the following:

• • 1. New variety displays a more diminutive morphology than this comparator.
  • 2. New variety exhibits much smaller leaves and ramifications than this comparator.
  • 3. ‘Lilliput’ produces leaves that are monotone emerald green, whereas ‘Variegta’ produces mint green leaves, margined with pale yellow.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The photographs were taken using conventional techniques and equipment. While the colors in these photographs may display variances of color as compared to the living cultivar, due to LRV (light reflectance value), they are as accurate as possible using conventional photographic techniques. Colors in the photographs may appear to differ slightly from the color values cited in the botanical description, which accurately describe the colors of new Portulacaria afra ‘Lilliput’.

FIG. 1 illustrates in full color the rosette being described of Portulacaria afra ‘Lilliput’, grown in a greenhouse (approximately 2500 foot candles) in Vista, Calif., at approximately 1 year.

FIG. 2 illustrates in full color a comparison of stems and foliage of 4 Portulacaria afra varieties. On the far left is Portulacaria afra ‘Macrophylla’, next from the left Portulacaria afra (unnamed parent), third from the left, Portulacaria afra ‘Prostrata’. Furthest right is Portulacaria afra ‘Lilliput’. All plants were grown in a greenhouse (approximately 2500 foot candles) in Vista, Calif.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Color Chart, 2007 edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘LILLIPUT’ plants in a commercial shadehouse in Vista, Calif. Temperatures ranged from 34° F. to 90° F. during the night and day. No artificial light, photoperiodic treatments or chemical treatments were given to the plants. Natural light conditions were approximately 3000 to 4000 foot candles of light. Measurements and numerical values represent averages of typical plant types.
