Latin name of the genus and species: Allium schoenoprasum.
Variety denomination: ‘G22087’.
BACKGROUND OF THE INVENTION
The new Allium cultivar is a product of a planned breeding program conducted by the inventor at a research nursery in Bellefonte, Pennsylvania. The self-pollination resulting in this new variety was made in June of 2021.
The parent is the unpatented proprietary variety referred to as Allium ‘G13-594’. The new variety was selected in August of 2022 by the inventor in a group of seedlings resulting from the 2021 self-pollination, in a nursery in Bellefonte, Pennsylvania.
Asexual reproduction of the new cultivar was performed by division, at the same nursery in Bellefonte, Pennsylvania during August of 2022, and has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.
SUMMARY OF THE INVENTION
The cultivar ‘G22087’ 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 ‘G22087’. These characteristics in combination distinguish ‘G22087’ as a new and distinct Allium cultivar:
- 1. Large, dark pink flowers.
- 2. Broad foliage, wider than typical for garden chives.
- 3. Stiffly upright habit.
- 4. Thick, stiff, upright flower stems.
- 5. Constant flowering though Summer.
PARENT COMPARISON
Plants of the new cultivar ‘G22087’ are similar to plants of the parent in most horticultural characteristics; however, plants of the new cultivar ‘G22087’ differ in the following:
- 1. ‘G22087’ is more uniform in leaf size than seed parent G13-594.
- 2. The foliage of ‘G22087’ is more glaucous blue-green in color than seed parent G13-594.
- 3. ‘G22087’ is more uniform in display of the desired upright habit than is G13-594.
- 4. ‘G22087’ is more vigorous and produces more divisions, more quickly than G13-594.
- 5. ‘G22087’ produces fewer seeds than G13-594 when self-pollinated. Neither variety produces many seeds when grown in isolation and self-pollinated, but new variety ‘G22087’ produces almost none, whereas breeding line G13-594 will routinely produce self-seed late in the season.
COMMERCIAL COMPARISONS
Plants of the new cultivar ‘G22087’ are comparable to the commercial variety Allium ‘Dolores’, unpatented and produced by seeds. The two Allium varieties are similar in most horticultural characteristics, however, the new variety ‘G22087’ differs in the following:
- 1. ‘G22087’ has larger, thicker broader leaves than ‘Dolores’.
- 2. Leaves of ‘G22087’ leaves are more intensely glaucous-blue in color, compared to the medium green leaf color of the comparator ‘Dolores’.
- 3. ‘G22087’ has more stiffly upright foliage than ‘Dolores’.
- 4. ‘G22087’ has much larger flowers than ‘Dolores’.
- 5. ‘G22087’ produces a more vigorous and larger plant than the comparator ‘Dolores’.
Plants of the new cultivar ‘G22087’ are comparable to the unnamed, seed produced commercial garden Allium commonly found in the horticulture market. The new cultivar ‘G22087’ differs in the following:
- 1. ‘G22087’ has larger, longer leaves than common garden chive.
- 2. ‘G22087’ has thicker and broader leaves, and of a more glaucous blue-green color, than common garden chives.
- 3. ‘G22087’ has more stiffly upright foliage than do common garden chives.
- 4. ‘G22087’ displays larger, deeper lavender-pink flowers, and which remain healthy and in harvestable condition, than are available on common garden chives.
- 5. ‘G22087’ has more stiffly upright and thicker flower stems than does common garden chives.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photograph in FIG. 1 illustrates a typical flowering plant of ‘G22087’ grown outdoors in Columbus, OH at approximately 8-months old in a 1-gallon pot.
FIG. 2 illustrates a close-up view of the flowers.
The photographs were 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.
