Submit Your Cultivar Name For Addition To The Register And Publication In The Herald

As ICRA for Brugmansia and Datura, we have a responsibility to ensure that your new cultivar is named in accordance with the International Code of Nomenclature for Cultivated Plants. The Registrar will be very happy to advise you on such technical issues, should any arise.

A key consideration is whether the plant is a cultivar. A ‘seedling’, i.e. a plant grown to flowering from seed, is not a cultivar and cannot be given a cultivar name. The seedling must first have been vegetatively propagated (at least in the case of Brugmansia) so that an assemblage of duplicate plants exists. The plant must also have been observed over at least two flowering seasons to ensure that the characteristics the new cultivar has been selected for are stable, and not just transient features.
The definition or recognition of a cultivar in Datura (where cultivars are usually, though not always, perpetuated by seed) can be more complex, which is why we do not, at this juncture, provide a form for submitting a new cultivar in this group. We are happy to discuss naming new Datura cultivars on a case by case basis.

We are not here to pass judgement on the quality of your cultivar! However, we mention in passing that it may be worth your considering whether a proposed new cultivar is actually contributing something new, different or better, at least within the country in which it has been raised. There is a field in the registration form for “noteworthy characteristics” where you can indicate the new cultivar’s strong, interesting or unique points.

A “Breeding History Set” will need to be cited for your Brugmansia cultivar. There is an explanation of these below but you can leave this blank if you like and we will complete that part for you if you have difficulty working it out.

Name of Breeding History Set to which the cultivar belongs:
For single-species cultivars

• Arborea…includes all cultivars (cvs) that are pure B. arborea
• Aurea…includes all cvs that are pure B. aurea
• Insignis…includes all cvs that are pure B. insignis
• Sanguinea…includes all cvs that are pure B. sanguinea
• Suaveolens…includes all cvs that are pure B. suaveolens
• Versicolor…includes all cvs that are pure B. versicolor
• Vulcanicola…includes all cvs that are pure B. vulcanicola

Example: ‘Ecuador Pink’ belongs in the Versicolor Set because it is a pure form of B. versicolor and only carried genes of that species.

For two-species hybrid cultivars

• Aurinsi…includes all hybrid combinations of B. aurea and B. insignis
• Candida…includes all hybrid combinations of B. versicolor and B. aurea
• Rubella…includes all hybrid combinations of B. arborea and B. sanguinea
• Suarea…includes all hybrid combinations of B. suaveolens and B. aurea
• Suaver…includes all hybrid combinations of B. suaveolens and B. versicolor
• Suavinsi…includes all hybrid combinations of B. suaveolens and B. insignis
• Verinsi…includes all hybrid combinations of B. versicolor and B. insignis
• Vulsa…includes all hybrid combinations of B. vulcanicola and B. sanguinea
• Vularbo…includes all hybrid combinations of B. vulcanicola and B. arborea

Example: ‘Bridesmaid’ belongs in the Candida Set because it is a hybrid of ‘Rothkirch’ (Aurea) and ‘Charleston’ (Candida) and therefore only carried genes of B. versicolor and B. aurea.

For three-species hybrid cultivars

• Arbovulsa …includes all hybrid combinations of B. arborea, B. vulcanicola and B. sanguinea
• Suaverinsi …includes all hybrid combinations of B. suaveolens, B. versicolor and B. insignis
• Suavinsaurea …includes all hybrid combinations of B. suaveolens, B. insignis and B. aurea
• Cubensis …includes all hybrid combinations of B. versicolor, B. suaveolens and B. aurea
• Verinsaurea …includes all hybrid combinations of B. versicolor, B. insignis and B. aurea

Example: ‘Goldkrone’ belongs in the Cubensis Set because it is a hybrid between ‘Charles Grimaldi’ (Cubensis) and ‘Goldenes Kornett’ (Aurea),‘Charles Grimaldi’ being a hybrid of ‘Dr Seuss’ (Cubensis) and ‘Frosty Pink’ (Suaveolens). ‘Goldkrone’ therefore only carries genes of B. aurea, B. suaveolens and B. versicolor.

For Four-species hybrid cultivars

• Siva …includes all hybrid combinations of B. suaveolens, B. insignis, B. versicolor and B. aurea

Example: ‘Schloss Ricklingen’ belongs in the Siva Set because it is a hybrid of ‘Cumbaya’ (Insignis) and ‘Ocre’ (Cubensis), and therefore carries genes of B. aurea, B. insignis, B. suaveolens and B. versicolor.

Your listing will be evaluated for thoroughness and the name checked for correctness. Your photos will also be evaluated. Please submit photos that are at least 800 x 800 pixels in size, but no larger than 250K file size. The blooms should be featured prominently in the photograph, and very clear. They should be representative of what the average blooms look on that cultivar. (For example, if they start white and turn pink, please submit photos after the color change has completed). 5 photos are required. 3 with blooms from different angles (2 different side shots, and one photo of the face of the bloom), one of the overall plant/shrub, and one with a close up of the foliage. Your photos will be sent to ISHS (International Society for Horticultural Science) with your registration as well as used for printing for The Herald, therefore we require non-watermarked pictures. By uploading your images on this form, you give BGI permission to use those photos in other areas on BGI’s website, such as the Galleries or the Databases, and on BGI’s Facebook and Twitter accounts. If you prefer we do not use these photos in any place other than the Database and published in The Herald, please check that option in the form below.

Once you have submitted your registered cultivar, the submission is accepted unless contacted by the registry officer.
