USPP28110P3 - Cotyledon hybrid named ‘Mint Truffles’ - Google Patents

Abstract

A new and distinct Cotyledon cultivar named ‘Mint Truffles’ is disclosed, characterized by a compact morphology, contrasting silvery mint-green leaves margined in crimson. Plants freely offset at an early age, allowing plant to be produced commercially as a clustering 9 cm. Plants, can also be produced in a larger pot size for the landscape. Free offset production at an early age enables faster propagation of the cultivar in the commercial nursery. Plants root quickly and grow vigorously; these characteristics, in combination with the tendency to freely offset at an early age, result in attractive clusters quickly, enhancing production intervals in the commercial environment. The new variety is a Cotyledon, part of the Crassulaceae complex that includes Aeonium, Echeveria, Graptopetalum, Pachyphytum, Sedum and others. Cotyledon is a popular genus, typically produced as container plants for the patio, or as landscape plants.

Description

Latin name of the genus and species: Cotyledon hybrid.

Variety denomination: ‘Mint Truffles’.

BACKGROUND OF THE INVENTION

The new cultivar, Cotyledon ‘Mint Truffles’, is a product of a planned breeding program. The new variety originated from a cross pollination of the proprietary, unpatented seed parent Cotyledon ‘MAC03’ with the pollen parent, the proprietary, unpatented pollen parent Cotyledon ‘ORB06’. The cross pollination was made during August, 2011, in Vista, Calif. at a commercial greenhouse. The new cultivar ‘Mint Truffles’ was discovered by the inventor, Renee O Connell, in March, 2012, at a commercial greenhouse in Vista, Calif.

Asexual reproduction of the new cultivar ‘Mint Truffles’ was first performed in Vista, Calif., at a commercial greenhouse, by vegetative terminal cuttings in April, 2012. Cotyledon ‘Mint Truffles’ has since produced multiple generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Mint Truffles’ 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 Cotyledon ‘Mint Truffles’. These characteristics in combination distinguish ‘Mint Truffles’ as a new and distinct Cotyledon cultivar:

• • 1. Cotyledon ‘Mint Truffles’ displays a low growing morphology, in combination with silvery mint-green leaves, margined with red.
  • 2. Cotyledon ‘Mint Truffles’ exhibits a compact growth habit, enabling production for small pot sizes, such as 9 cm, as well as for 1, 2 and 5 gallon pots for the landscape.
  • 3. Cotyledon ‘Mint Truffles’ is freely offsetting, at an early age, forming low-growing clusters quickly.
  • 4. Cotyledon ‘Mint Truffles’ is easily and rapidly propagated due to fast rooting, vigorous growth, and prolific offsetting, enhancing production times in the commercial nursery.
  • 5. Cotyledon ‘Mint Truffles’, when planted out in the landscape, continues to have a compact growth; rather than growing tall and lanky, the new cultivar ‘Mint Truffles’ spreads laterally.

PARENTAL COMPARISON

Plants of the new cultivar ‘Mint Truffles’ can be compared to plants of the unpatented, proprietary Cotyledon ‘MAC03’, and are similar in most horticultural characteristics. However, plants of the new cultivar ‘Mint Truffles’ display a more compact morphology, not exhibited by Cotyledon ‘MAC03’. The new cultivar ‘Mint Truffles’ is freely offsetting at an early age, in contrast to ‘MAC03’, which produces few offsets. In addition, the new cultivar ‘Mint Truffles’ exhibits smaller mint-green leaves with a red margin, in comparison to the larger, lime-green leaves produced by the seed parent Cotyledon ‘MAC03’. The new cultivar ‘Mint Truffles’ produces compact plants with many offsets, and grows laterally to form a cluster, in contrast to the seed parent Cotyledon ‘MAC03’, which tends to become tall and leggy with sparse branching.

Plants of the new cultivar ‘Mint Truffles’ can be compared to plants of pollen parent Cotyledon ‘ORB06’, and are similar in most horticultural characteristics. However, plants of the new cultivar ‘Mint Truffles’ exhibit early and free offsetting, in contrast to the sparse offsetting produced by the seed parent by Cotyledon ‘ORB06’. Further, the new cultivar ‘Mint Truffles’ exhibits smaller mint-green leaves with bright red margins, in contrast to the grayish leaves produced by the pollen parent Cotyledon ‘ORB06’. Additionally, the new cultivar ‘Mint Truffles’ can be produced as a 9 cm pot size due to its compact growth and early offsetting, whereas the pollen parent Cotyledon ‘ORB06’ does not make an attractive 9 cm as the leaves and branches are too large, and do not convey the concept of the “small cluster” conveyed by the new cultivar ‘Mint Truffles’.

COMMERCIAL COMPARISON

The new cultivar ‘Mint Truffles’ can be compared to the unpatented commercial variety Cotyledon orbiculata v. orbiculata. Plants of the Cotyledon orbiculata v. orbiculata are similar to plants of the new cultivar ‘Mint Truffles’ in most horticultural characteristics. However, the new cultivar ‘Mint Truffles’ exhibits a compact form, in contrast to the taller, lanky form exhibited by Cotyledon orbiculata v. orbiculata. In addition, ‘Mint Truffles’ forms smaller leaves of mint-green, margined with a contrasting bright red, whereas Cotyledon orbiculata v. orbiculata forms larger, non-uniform gray to gray white leaves. The new cultivar ‘Mint Truffles’ is freely offsetting from an early age, forming attractive clusters, whereas Cotyledon orbiculata v. orbiculata has a upright, lanky, lax growth habit, and does not produce offsets until much older. For this reason, the new cultivar, ‘Mint Truffles’ due to its quick rooting, freely offsetting and compact growth habit, produces a morphologically aesthetic cluster, thereby enhancing production time in a commercial nursery, in contrast to Cotyledon orbiculata v. orbiculata.

The new cultivar ‘Mint Truffles’ can be compared to the unpatented commercial variety Cotyledon orbiculata v. ‘Macrantha’. Plants of Cotyledon orbiculata v. ‘Macrantha’ are similar to plants of the new cultivar ‘Mint Truffles’ in most horticultural characteristics. However, the cultivar ‘Mint Truffles’ exhibits a more compact growth form, growing laterally, rather than vertically, as compared to the lanky, upright growth habit of Cotyledon orbiculata ‘Macrantha’. In addition, the new cultivar ‘Mint Truffles’ is freely offsetting from an early age, enhancing the propagation rate, and producing a compact, aesthetically attractive cluster, as compared with Cotyledon orbiculata ‘Macrantha’, which produces offsets sparingly and at an older age.

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 the new Cotyledon plant.
