Abstract
A new and distinct Rhamnus cultivar named ‘SMNRFBT’ is disclosed, characterized by narrow leaves, good branching and dense foliage. The new variety is a Rhamnus, normally used for outdoor ornamental purposes.
Description
Latin name of the genus and species: Rhamnus frangula.
Variety denomination: ‘SMNRFBT’.
The new Rhamnus cultivar is a product of a naturally-occurring whole plant mutation discovered by the inventor, Timothy Wood, in Grand Haven, Mich. The parent is the commercial variety Rhamnus ‘Ron Williams’, U.S. Plant Pat. No. 14,791.
The new variety was found and selected in Spring of 2017 by the inventor in a group of seedlings in a nursery in Grand Haven, Mich.
Asexual reproduction of the new cultivar has been performed by softwood cuttings. This was first performed at the same nursery in Grand Haven, Mich. in Spring 2017, and has shown that the unique features of this cultivar are stable and reproduced true to type in multiple successive generations.
The cultivar ‘SMNRFBT’ 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 ‘SMNRFBT’ These characteristics in combination distinguish ‘SMNRFBT’ as a new and distinct Rhamnus cultivar:
-
- 1. Narrow leaves.
- 2. Dense foliage.
- 3. Good branching.
Plants of the new cultivar ‘SMNRFBT’ are similar to plants of the parent in most horticultural characteristics; however, plants of the new cultivar ‘SMNRFBT’ differ in the following;
-
- 1. The new variety has narrower leaves than the parent.
- 2. The new variety has better branching toward the base than the parent.
- 3. The new variety has denser foliage than the parent.
Plants of the new cultivar ‘SMNRFBT’ are comparable to Rhamnus ‘SMNRFBL’ co-pending, having application Ser. No. 16/602,606. The two Rhamnus varieties are similar in most horticultural characteristics; however, the new variety ‘SMNRFBT’ differs in the following;
-
- 1. The new variety has narrower leaves than this comparator.
The accompanying photograph illustrates in full color a typical plant of ‘SMNRFBT’ in a 2 gallon pot. Age of the plant photographed is approximately 2-3 years old from a rooted cutting. The photograph was 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.
In the following description, color references are made to The Royal Horticultural Society Colour Chart 2015 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘SMNRFBT’ plants grown in a poly greenhouse during July 2017, in Grand Haven, Mich. The growing temperature ranged from approximately 18° C. to 27° C. during the day and from approximately 5° C. to 10° C. during the night. General light conditions are normal sunlight and numerical values represent averages of typical plant types.
