The present invention relates to a new, distinct and stable cultivar of Monolena, hereinafter referred to as ‘MIDNIGHT GLORY’. The present invention relates to seeds which are the Monolena ‘MIDNIGHT GLORY’, as well as, plants and plant parts produced by these seeds which have all of the morphological and physiological characteristics of the Monolena cultivar ‘MIDNIGHT GLORY’. The present invention also relates to methods for producing these seeds and plants of the Monolena cultivar ‘MIDNIGHT GLORY’. Furthermore, the present invention relates to a method of producing progeny Monolena plants by crossing Monolena ‘MIDNIGHT GLORY’, as either the female or seed or male or pollen parent, with another Monolena plant and selecting progeny.
The present invention relates to a new, distinct and stable cultivar, botanically known as Monolena primuliflora, and hereinafter referred to by the variety denomination ‘MIDNIGHT GLORY’. The new Monolena ‘MIDNIGHT GLORY’ originated from a familial cross of unnamed proprietary seedlings. Development of the parent varieties was conducted over several years, as part of a controlled breeding program by the inventors. The cross resulting in the new variety ‘MIDNIGHT GLORY’ was made during 2018. ‘MIDNIGHT GLORY’ first flowered in 2019, in Assendelft, The Netherlands. The objective of the breeding program is to create new Monolena plants with interesting characteristics for the ornamental market. Characteristics sought included durable plants with long-lastingness for indoor ornamental uses, as well as colorful foliage.
Monolena is a member of the Melastomataceae family. Monolena primuliflora is native to Peru and Ecuador. In its native moist habitat plants grow epiphytically. Plants under cultivation are terrestrial. Plants consist of a basal caudex, from which emerges a rosette of decorative foliage. Flowers are not considered to have ornamental value.
Monolena primuliflora are not well-known in the industry at this time. Some specialty growers of novelty ornamental plants offer unnamed selections of Monolena primuliflora in small quantities. The new cultivar with its unique greyed-purple and dark yellow-green foliage coloration and phenotypically uniform reproduction from seed is a novel and useful introduction to the ornamental plant market. Monolena cultivars that can be easily propagated by seed, and reproduce the desired features consistently are a valuable introduction to the horticultural industry.
The new Monolena ‘MIDNIGHT GLORY’ was developed through a controlled breeding program and exhibits unique, desirable and stable characteristics.
The present invention provides Monolena plant selections that are a long-lasting medium sized, cultivar having greyed-purple and dark yellow-green foliage.
These and other objectives have been achieved in accordance with the present invention which provides ‘MIDNIGHT GLORY’ as a new Monolena cultivar that is a product of a planned breeding program conducted by the inventors, Elly Bak and Nico D. M. Steur, in Assendelft, The Netherlands. The cross resulting in the new cultivar ‘MIDNIGHT GLORY’ is a familial cross of proprietary seedlings which have a sufficient degree of homozygosity such that the progeny of the cross are genotypically and phenotypically uniform. The new cultivar ‘MIDNIGHT GLORY’ therefore can be produced by sexual reproduction by crossing the parental to produce a population of progeny plants, each of which has the combination of characteristics as herein disclosed for the new variety ‘MIDNIGHT GLORY’.
Seeds which are the cultivar ‘MIDNIGHT GLORY’ are produced by crossing the parental selections and have been deposited with the NCIMB limited, Ferguson Building, Craibstone Estate, Bucksburn, Aberdeen, AB21 9YA, United Kingdom.
The present invention relates to seeds which produce Monolena ‘MIDNIGHT GLORY’. The present invention also relates to Monolena plants, and parts thereof, having all the physiological and morphological characteristics of Monolena ‘MIDNIGHT GLORY’. The present invention relates to a plant produced from seeds which are Monolena ‘MIDNIGHT GLORY’. The present invention also relates to plant parts, such as pollen, seeds or inflorescence produced by Monolena ‘MIDNIGHT GLORY’.
The present invention relates to a method of producing seed which are Monolena ‘MIDNIGHT GLORY’, by a crossing the unpatented proprietary parent selections of Monolena primuliflora and harvesting seeds produced from said cross.
The present invention also relates to a method of producing plants having all the physiological and morphological characteristics of the Monolena ‘MIDNIGHT GLORY’ comprising the steps of (a) crossing the proprietary parent selections of Monolena primuliflora (unpatented). (b) harvesting seeds produced from said cross; and (c) producing plants from said harvested seeds.
The following traits have been repeatedly observed and are determined to be unique characteristics of ‘MIDNIGHT GLORY’ which in combination distinguish this Monolena as a new and distinct cultivar:
1. Year-round growth.
2. Ornamental foliage plant with decorative greyed-purple and dark yellow-green foliage.
3. Long-lasting qualities as an indoor ornamental plant.
4. Medium sized plant.
The new Monolena ‘MIDNIGHT GLORY’ can be compared to the unpatented unnamed Monolena primuliflora sold in specialty nurseries. Plants of the new cultivar ‘MIDNIGHT GLORY’ are similar to plants of these Monolena primuliflora plants in most horticultural characteristics, however the varieties differ in the following:
1. Monolena ‘Midnight Glory’ produces foliage with distinctive under surface coloration of greyed-purple, and a dark yellow-green upper surface, this comparator has light green foliage.
2. Plants of this comparator are less vigorous.
3. Plants of this comparator are not produced uniformly from seed.
‘MIDNIGHT GLORY’ has not been tested and observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, frequency of fertilization, composition of fertilizer, flowering treatment, day length and humidity, without any change in the genotype of the plant.
The patent or application file contains at least one drawing executed in color. Copies of this patent or patent application publication with color drawings will be provided by the Office upon request and payment of the necessary fees.
The accompanying photograph illustrates the overall appearance of the new Monolena cultivar ‘MIDNIGHT GLORY’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describes the color of ‘MIDNIGHT GLORY’.
The accompanying drawing shows a side view perspective of a typical potted plant of ‘MIDNIGHT GLORY’, at approximately 6 months of age from potting size in a 13 cm pot.
The present invention was created by the inventors, Elly Bak and Nicolaas D. M. Steur in 2018 and flowered for the first time in 2019 in Assendelft, The Netherlands.
This invention is directed to Monolena plant having all the morphological and physiological characteristics of the cultivar ‘MIDNIGHT GLORY’ produced from seeds which are the product of the cross of the proprietary parental selections of Monolena primuliflora Both parents have a sufficient degree of homozygosity such that the progeny of the cross were, and continue to be, phenotypically uniform. The new cultivar ‘MIDNIGHT GLORY’ can therefore be produced by sexual reproduction by crossing of the parental Monolena primuliflora selections to produce a population of progeny plants, each of which has the combination of characteristics herein disclosed for the new cultivar ‘MIDNIGHT GLORY’.
The new cultivar ‘MIDNIGHT GLORY’ has not been produced asexually, however this is likely possible, though not commercially viable. asexually reproducing progeny from the cross of the parental selections. Sexually reproduced progeny have demonstrated that the new cultivar reproduces true-to-type and that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and predictable.
The aforementioned photograph, together with the following observations, measurements and values describe the new Monolena primuliflora ‘MIDNIGHT GLORY’ as grown in a greenhouse in Assendelft, The Netherlands, under conditions which closely approximate those generally used in commercial practice. Plants of ‘MIDNIGHT GLORY’ were grown in a greenhouse with day temperatures ranging from 20° C. to 28° C. and night temperatures ranging from 18° C. to 23° C. No artificial lighting or photoperiodic treatments were conducted.
