Abstract
A new variety of Lamium plant named ‘Orchid Frost Grande’ that is distinguishable by vigorous growth, prostrate well-branched plant habit, heart-shaped leaves which are silver-grey in color and accented by a contrasting dark green marginal variegation and large red-purple inflorescences and individual flowers which are held upright along the stems and also pendulous at the end of the stems, is disclosed.
Description
Genus and species: Lamium maculatum.
Variety denomination: ‘Orchid Frost Grande’.
The present disclosure relates to a new and distinct variety of Lamium plant, also known as Dead Nettle or Spotted Dead Nettle, a perennial that is grown for use as an ornamental landscape and container plant. The new variety is known botanically as Lamium maculatum and will be referred to hereinafter by the variety name ‘Orchid Frost Grande’.
The new Lamium variety ‘Orchid Frost Grande’ resulted from chemical treatment of the inventor's variety Lamium ‘Orchid Frost’ (U.S. Plant Pat. No. 11,122). Specifically, Stage II tissue cultured microplants of ‘Orchid Frost’ were treated in the holding laboratory with a 0.001% solution of the chemical colchicine during February 2019 and observed after 6 months. The laboratory treatments resulted in a range of progeny including probable tetraploid mutations which would require further evaluation in vivo.
In November 2019, the progeny was transferred as unrooted cuttings to a commercial nursery in Oxnard, Calif. where the plants were rooted and grown on, and asexually propagated under the inventor's direction.
In April 2020, the inventor selected the present variety ‘Orchid Frost Grande’ for its markedly larger inflorescence and individual flowers when compared with the parent variety ‘Orchid Frost’. In addition, ‘Orchid Frost Grande’ bears larger leaves and grows rapidly all of which indicates to the inventor that ‘Orchid Frost Grande’ is a tetraploid variety.
‘Orchid Frost Grande’ was first asexually propagated in January 2020 in a greenhouse in Oxnard, Calif. The inventor has confirmed that ‘Orchid Frost Grande’ is stable and reproduces true to type in successive generations of asexual reproduction.
The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘Orchid Frost Grande’. ‘Orchid Frost Grande’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without however, any variance in genotype.
-
- 1. ‘Orchid Frost Grande’ exhibits a prostrate well-branched plant habit.
- 2. The leaves of ‘Orchid Frost Grande’ are heart-shaped and silver-grey in color, accented by a contrasting uniformly dark green marginal variegation.
- 3. ‘Orchid Frost Grande’ grows and flowers rapidly. Flowering plants may be produced in 10 to 12 weeks from a cutting.
- 4. The inflorescences of ‘Orchid Frost Grande’ are large and held upright along the stems and pendulous at the end of the stems.
- 5. The buds and flowers of ‘Orchid Frost Grande’ are dark red-purple in color.
- 6. ‘Orchid Frost Grande’ may be grown and used as a perennial in the garden or landscape, or as a ground cover, or planted in mixed containers for year-round foliage effect and flowering from spring to fall.
The accompanying color photographs illustrate the overall appearance of the new Lamium variety ‘Orchid Frost Grande’ showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Photographs were taken in April 2020 in Oxnard, Calif. from a five months old plant grown outdoors in a 3-gallon container, with one pinch after initial cutting establishment and without any chemical growth regulators. Colors in the photographs may differ from the color values cited in the detailed botanical description, which more accurately describes the actual colors of the new variety ‘Orchid Frost Grande’.
The following detailed descriptions set forth the distinctive characteristics of ‘Orchid Frost Grande’. Observations, measurements, values, and comparisons were collected in April 2020 in Santa Barbara, Calif. from a five months old plant which had been growing outdoors in full sun in a 3 gallon container in Oxnard, Calif., with one pinch after initial cutting establishment and without any chemical growth regulators. Color determinations were made in accordance with The 2007 Royal Horticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used.

In comparison with the parent, ‘Orchid Frost’, which is also the closest variety known to the inventor, ‘Orchid Frost Grande’ grows more rapidly, is more vigorous and bears inflorescences and flowers which are approximately twice as large. This vigor is attributed to the presumed tetraploid constitution of ‘Orchid Frost Grande’ and is its distinguishing characteristic.
Whereas the leaves of ‘Orchid Frost Gold’ are lime green in color with wide mid-green edges, the leaves of ‘Orchid Frost Grande’ are silver-white in color and exhibit narrower dark green edges. In addition, the flowers and buds of ‘Orchid Frost Gold’ are smaller and paler red-purple in color than the darker red-purple buds and flowers of ‘Orchid Frost Grande’.
