Spotting a narrow leaf on a plant is easy. It is harder to tell what it is: an ordinary leaf at a particular stage of development, a chance variation, or a plant from a long-established line. AD17 has almost none of the familiar fan and no teeth along the edge, and its name sounds like a specimen number in a collection.
In KalySeeds materials, the name is given in full as Apricot Delia 17. Older records also use Aprico Delia, without the letter t. Similar spellings sometimes stand for different stages of the same program.
Before the number appeared
A description of AD17 survives on Grower.ch. On December 21, 2019, A. Schmid opened a thread titled “[Kalyseeds] A.D.17” and quoted the description current at the time. It calls AD17 a selection from Aprico Delia. The predecessor is described as a plant with lance-shaped, entire-margined leaves, green and variegated. Sessile leaves, meaning leaves without a distinct stalk, are noted separately.
This is a quotation of catalog text. By the end of 2019, the name AD17 was already in public circulation. Grower.ch, December 21, 2019
According to this text, Aprico Delia is a separate, earlier generation, the predecessor of AD17.
The Afghan branch of SWAG
A later KalySeeds description, reproduced by SeedFinder, places AD17 in the SWAG family. The creator writes that the single-leaflet form was selected from Afghan SWAG, and dates the introduction of Vanilluna Kush into its history to 2015.
The same description treats AD17 more broadly than the 2019 quotation. Besides lance-shaped blades, there are three-lobed leaves, curved forms and different leaf positions relative to the stem. Some leaves sit directly on the stem, while others have a distinct stalk. So “without a leaf stalk” from the early description does not fit every plant bearing the name. KalySeeds description of AD17
The history of Apricot Pie Mutant Mix gives a more detailed name for the original branch: Purple Afghan SWAG, also known as Skinny Purple. The creators state directly that AD17 is connected to this population. They explain the name Skinny by the narrow leaf shape. Description of Apricot Pie Mutant Mix
All of these descriptions come from one breeding circle: KalySeeds and TerpyZ.
The lance-shaped family
Another version appears in TerpyZ’s overview of leaf forms. There, Apricot Delia and AD17 sit at the intersection of lance-shaped lines and smooth-edged SWAG. The author links the lance-shaped family in his collection to material from the Amur region, and the absence of teeth to SWAG. TerpyZ overview
The overview describes the development of the whole group, and the strain listing describes AD17 specifically. The Amur material belongs to the history of the lance-shaped family as a whole.
AD and GPP are different families. In TerpyZ’s current terminology, AD is characterized above all by a smooth edge, and GPP by a toothed one. Both can have an elongated, single-leaflet form, and hybrid connections between them are reported. How TerpyZ distinguishes the families
DeMaddin’s recollection
By the summer of 2020, AD17 is mentioned beyond the catalog. On The-Greenleaf, DeMaddin, who describes himself as a former KalySeeds assistant, lists it alongside SWAG and Skinny Purple. He worked with KalySeeds in 2015 and wrote about it in 2020. DeMaddin’s post of June 4, 2020
Around AD17, people, neighboring lines and a shared interest in smooth leaf edges come into view.
Apricot Delia continues
The predecessor shows up in the history of Apricot Roses SWAG. The creators directly name Apricot Delia as the predecessor of AD17 and trace Apricot Roses to two branches: one through Apricot Delia, the other through SWAG Original. Leaf forms from a single blade to five lobes are reported for the new line. Description of Apricot Roses SWAG
On February 1, 2022, TerpyZ uploaded a photograph of Apricot Roses SWAG to SeedFinder. By that date, the line was already publicly visible. Photograph record
Apricot Roses Mutant Mix exists alongside it. Its description shows noticeably more variable leaves. It is a separate entry and a separate way the program continued. Description of Apricot Roses Mutant Mix
Apricot Pie Mutant Mix leads back to AD17: its creators name variegated AD17 and Ed Rosenthal Sativa SWAG as the parent branches. This is how the name AD17 reaches later pedigrees.
The line and the mutation
AD17 is a named line from the SWAG family. Collectors call it a mutation for short: it is an easy way to name an unusual form.
Sessile leaves, an entire margin, fewer lobes and variegation are four separate traits. Together they make the plant recognizable.
AD17 went from a single name in the KalySeeds collection to a network of descendants in which the smooth, lance-shaped leaf appears in ever new combinations.
