Aloe plant named `ALLIGATOR`

Abstract

A new and distinct cultivar of Aloe plant named `ALLIGATOR` is disclosed, characterized by upright rosette of rigid green leaves, liberally dappled with light yellow-green or greyed-green spots and margined by reddish teeth, colored near Greyed-Red 180A. Plants tolerate full sun as well as observed low temperature tolerance to -2.degree. C. Offsets form freely on plants with maturity, creating ornate clusters. The new variety is an Aloe, typically produced as a garden or container plant.

Description

Latin name of the genus and species: Aloe hybrid.

Variety denomination: `ALLIGATOR`.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The seed parent is the unpatented proprietary Aloe hybrid `FRK 02`. The pollen parent is the unpatented proprietary Aloe hybrid `FRK 17`. The crossing was made in March 2014 at a commercial greenhouse in Vista, Calif. `ALLIGATOR` was selected by the inventor in September 2015.

Asexual reproduction of the new cultivar `ALLIGATOR` was first performed by tissue culture at a commercial laboratory in Vista, Calif. in October 2015. `ALLIGATOR` has since produced several generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar `ALLIGATOR` 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 `ALLIGATOR`. These characteristics in combination distinguish `ALLIGATOR` as a new and distinct Aloe cultivar: 1. Aloe `Alligator` forms an attractive, upright rosette of rigid green leaves, liberally dappled with light yellow-green or greyed-green spots and margined by reddish teeth, colored near Greyed-Red 180A. 2. Aloe `Alligator` has demonstrated its value as a landscape plant that can be produced in full sun. 3. Aloe `Alligator` has exhibited cold tolerance to -2.degree. C. with no disfiguring. 4. Aloe `Alligator` produces offsets at larger pot size such as an 8'' or 10'', creating an ornate cluster.

PARENTAL COMPARISON

Plants of the new cultivar `ALLIGATOR` are similar to the seed parent in most horticultural characteristics. However, plants of the new variety differ from the seed parent in the following: 1. Aloe `Alligator` grows to a larger diameter than does Aloe `FRK 02`. 2. Aloe `Alligator` does not exhibit the more upturned morphology of the leaves that Aloe `FRK 02` displays. 3. Aloe `Alligator` exhibits stronger marginal teeth than does Aloe `FRK 02`. 4. Aloe `Alligator` produces more offsets than does Aloe `FRK 02`, and retains a more ornate morphology.

Plants of the new cultivar `ALLIGATOR` are similar to the pollen parent in most horticultural characteristics. However, plants of the new variety differ in the following: 1. Aloe `Alligator` produces offsets, whereas as Aloe `FRK 17` remains solitary. 2. Aloe `Alligator` exhibits a larger diameter to the rosette than does Aloe `FRK 17`. 3. Aloe `Alligator` has more dappled light yellow-green or greyed-green spots than does Aloe `FRK 17`.

COMMERCIAL COMPARISON

`ALLIGATOR` can be compared to the unpatented commercial variety Aloe `Blue Elf`. The two Aloe varieties are similar in most horticultural characteristics; however, the new variety differs in the following: 1. Aloe `Alligator` produces ornate rosettes of rigid green leaves, liberally dappled with light yellow-green or greyed-green spots, whereas Aloe `Blue Elf` exhibits taller rosettes of longer matte blue leaves with no spots. 2. Aloe `Alligator` fills an 8'' pot with a single cut, whereas Aloe `Blue Elf` fills an 8'' pot only after a much longer interval with the production of offsets. 3. Aloe `Alligator` displays wide, strong leaves which are contained within the perimeter of the pot, whereas Aloe `Blue Elf` produces softer, longer leaves which can break in shipping. 4. Aloe `Alligator` forms thick, rigid leaves that do not "blanch" or exhibit "tip death", whereas those of Aloe `Blue Elf` are thinner and are known to suffer "blanch" or "tip death" under certain circumstances in the commercial environment.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates in full color a top view of a typical plant of `ALLIGATOR` grown in a greenhouse in Vista, Calif. This plant is approximately 10 months old, shown in a 6-inch container. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION
