Abstract
A new and distinct Lavandula cultivar named ‘QL1’ is disclosed, characterized by dense, upright plants abundantly producing inflorescences with violet infertile bracts and darker violet true flowers. The new variety is a Lavandula, normally produced as an outdoor garden or container plant.
Description
Latin name of the genus and species: Lavandula stoechas ssp. pedunculata.
Variety denomination: ‘QL1’.
A product of a planned breeding program conducted by the inventor, Sabro Denmark. The objective of the breeding program was to produce new Lavender varieties for ornamental commercial applications. The open pollination resulting in this new variety was made during 2017.
A breeding block of more than 50 different unpatented, unnamed proprietary Lavandula stoechas ssp. pedunculata was organized for cross pollination, with the resulting seed bulk collected. The new variety was selected in July of 2019 by the inventor in a group of seedlings resulting from this cross-pollination. Exact parents cannot be identified.
Asexual reproduction of the new cultivar was performed by vegetative terminal cuttings. This was first performed at a research greenhouse in Denmark during July of 2019 and has shown that the unique features of this cultivar are stable and reproduced true to type in at least 2 successive generations.
The cultivar ‘QL1’ 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 ‘QL1’ These characteristics in combination distinguish ‘QL1’ as a new and distinct Lavandula cultivar:
-
- 1. Dense, upright plant.
- 2. Violet infertile bracts, dark violet fertile flowers.
- 3. Abundant flowering.
The parents cannot be identified for comparison.
Plants of the new cultivar ‘QL1’ are comparable to the variety Lavandula ‘LMAPU31-0’, U.S. Plant Pat. No. 29,658. The two Lavandula varieties are similar in most horticultural characteristics; however, the new variety ‘QL1’ differs in producing plants which are more upright, with longer internodes and longer flowerheads.
Plants of the new cultivar ‘QL1’ are comparable to the variety Lavandula ‘Larkman Bee’, U.S. Plant Pat. No. 20,840. The two Lavandula varieties are similar in most horticultural characteristics; however, the new variety ‘QL1’ differs in producing longer infertile bracts. Additionally plants of ‘QL1’ are more upright than this comparator.
Plants of the new cultivar ‘QL1’ can also be compared to the commercial variety Lavandula ‘Larkman Hazel’ U.S. Plant Pat. No. 20,894. These varieties are similar in most horticultural characteristics however, the new variety ‘QL1’ differs in producing longer overall inflorescence, of a darker color. Additionally plants of ‘QL1’ are more upright than the comparator and produce more inflorescences per plant.
The accompanying photographs in FIG. 1 illustrates in full color a typical plant of ‘QL1’ grown in a greenhouse in Denmark. Age of the plant photographed is approximately 30 weeks from a rooted cutting. FIG. 2 is a close-up view of the inflorescence.
The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance are as accurate as possible by conventional photographic techniques.
In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘QL1’ plants grown outdoors during Spring in Denmark. The growing temperature ranged from 10° C. to 35° C. during the day and from 5° C. to 25° C. during the night. General light conditions are bright, normal sunlight. Measurements and numerical values represent averages of typical plant types.
