plant named ‘MAUNA KEA’

Abstract

A new and distinct cultivar of Aloe plant named ‘MAUNA KEA’ is disclosed, characterized by a star shaped plant with serrated and flanged leaves, white and prominent red protuberances on leaf edges, and red flowers. 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: ‘MAUNA KEA’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The seed parent is the unpatented Aloe deltoideodonta Aloe x ‘White Lightning’. The pollen parent is the unpatented Aloe divaricata x Aloe intermedia x Aloe ‘White Lightning’. The crossing was made in January 2017 at a commercial greenhouse in Vista, Calif. ‘MAUNA KEA’ was found and selected by the inventor in June 2017 at the same greenhouse in Vista, Calif.

Asexual reproduction of the new cultivar ‘MAUNA KEA’ was first performed by tissue culture at a commercial laboratory in Vista, Calif. in July 2017. ‘MAUNA KEA’ 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 ‘MAUNA KEA’ 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 ‘MAUNA KEA’. These characteristics in combination distinguish ‘MAUNA KEA’ as a new and distinct Aloe cultivar:

• • 1. Leaves serrated and flanged on star shaped plant.
  • 2. White and prominent red protuberances on leaf edges.
  • 3. Red color flower inflorescence.
  • 4. Table top size Aloe, maturing at 8″ across.

PARENTAL COMPARISON

Plants of the new cultivar ‘MAUNA KEA’ 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. The new variety has a more compact rosette than the seed parent.
  • 2. The new variety has brighter, more colorful leaves than the seed parent.
  • 3. Distinct red and flanged pronounced leaf edge

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

• • 1. The new variety is a smaller plant than the pollen parent.
  • 2. The new variety produces a more pronounced and brighter red leaf edge.
  • 3. The new variety has a more orderly, attractive star-shaped rosette.

COMMERCIAL COMPARISON

‘MAUNA KEA’ can be compared to the unpatented commercial variety Aloe ‘Delta Dawn’. The two Aloe varieties are similar in most horticultural characteristics; however, the new variety differs in the following:

• • 1. The new variety is a smaller, more compact plant than this comparator.
  • 2. The new variety has more colorful leaves than this comparator.
  • 3. The new variety has brighter coloring of leaves at all light levels than this comparator.
  • 4. The new variety has a cleaner growth habit than this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates in full color a typical plant of ‘MAUNA KEA’ grown in a greenhouse in Vista, Calif. This plant is approximately 24 months old, shown in a 1-gallon 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

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.
