Abstract
A new and distinct cultivar of Hydrangea plant named ‘RLL-12-20’ is disclosed, characterized by purple-red new growth of foliage color, thick leaves, pink mophead inflorescence in non-aluminum-based media and blue inflorescence in aluminum-based media, and compact, rounded to spreading growth habit. The new variety is a Hydrangea, typically produced as an outdoor ornamental plant.
Description
Latin name of the genus and species: Hydrangea macrophylla.
Variety denomination: ‘RLL-12-20’.
The present invention relates to a new and distinct cultivar of Hydrangea macrophylla, a member of the Hydrangeaceae family, hereinafter referred to by its cultivar name ‘RLL-12-20’. This cultivar is grown primarily as an ornamental for landscape use and for use as a potted plant. The cultivar originated from an open-pollination of a red leaf Hydrangea macrophylla ‘Lilacina’ and unidentified pollen parentage in Watkinsville, Ga., in 2020, and was selected from the progeny by continued evaluation for growth habit, floral, and foliage characteristics.
‘RLL-12-20’ has been asexually reproduced by softwood cuttings since 2020 in Watkinsville, Ga. The characteristics of the cultivar have been stable and reproduced true to type in successive vegetative generations.
‘RLL-12-20’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘RLL-12-20.’ These characteristics in combination distinguish ‘RLL-12-20’ as a new and distinct Hydrangea cultivar:
-
- 1. Thick foliage with purple-red new growth and first year stems are reddish orange.
- 2. Deep purplish pink mophead inflorescence in non-aluminum-based media and light purplish-blue inflorescence in aluminum-based media.
- 3. Compact, rounded to spreading growth habit.
Plants of the new cultivar Hydrangea ‘RLL-12-20’ can be compared to the seed parent variety in most horticultural characteristics, however, plants of ‘RLL-12-20’ differ in the following:
-
- 1. ‘RLL-12-20’ is distinguished from its parent plant ‘Lilacina’ by its mophead inflorescence. ‘Lilacina’ is a lacecap.
- 2. The red new growth on ‘Lilacina’ is not as purple-red and turns green quicker than ‘RLL12-20’.
- 3. The foliage on ‘RLL-12-20’ is thicker than the foliage on ‘Lilacina’.
- 4. ‘RLL-12-20’ is compact compared to Red Leaf Hydrangea macrophylla ‘Lilacina’.
Plants of the new cultivar Hydrangea ‘RLL-12-20’ can be compared to the commercial variety Hydrangea macrophylla ‘H2002’, U.S. Plant Pat. No. 26,657. Plants of ‘RLL-12-20’ are similar to plants of ‘H2002’ in some horticultural characteristics, however, plants of ‘RLL-12-20’ differ in the following:
-
- 1. ‘RLL-12-20’ has deep purple Summer foliage; this comparator has some bronze coloration to the foliage, mainly in the Spring.
- 2. This comparator has a rose colored picotee flower; ‘RLL-12-20’ has either deep purplish pink inflorescences in non-aluminum-based media or light purplish-blue inflorescences in aluminum-based media.
- 3. The new variety has been observed to grow stronger in the environmental conditions of the South Eastern United States.
The accompanying illustrations show characteristics of the new cultivar in photographs as true to color as is reasonably possible to make in illustrations of this nature. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Hydrangea.
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the description were grown in 23.03 L containers under 50% shade under outdoor conditions in a nursery in Watkinsville, Ga. Plants were about two years old when the description was recorded. Two groups of plants were used for the description to describe the flower colors with and without aluminum. The first group was grown in a medium consisting of composted pine bark, with no aluminum present and a pH of 5.4. The second group was grown in a medium consisting of composted pine bark that was amended with 60 grams of aluminum sulphate and a pH of 5.3. Aluminum only affects flower including sepal, petal, pistil and stamen colors. Therefore, colors with and without aluminum are only specified for floral parts.
