AK-47

AK-47 is described by Leafly as a hybrid with Colombian, Mexican, Thai and Afghan ancestry. That four-region summary does not specify the order of crosses or an immediate parent pair. Serious Seeds' own history connects AK-47 with Simon's work before the company's founding in 1995. This adds a breeder account to the catalog context without certifying every later AK-47-labelled sample. Skunk, tobacco and earth remain reported flavor descriptors rather than evidence of pedigree.

Afghani

Afghani is a regional cannabis name associated with Afghanistan and appears in many reported family histories. A regional name can cover varied material, so this profile does not imply one uniform genetic or chemical sample.

Big Bud

Big Bud's reported background combines Afghani, Northern Lights and Skunk #1. Leafly traces its history from the United States to the Netherlands; the three names are recorded as ancestry without inventing a crossing order.

Blue Dream

Blue Dream is a California-associated hybrid whose reported family joins Blueberry and Haze. Leafly lists berry and sweet flavor descriptors and a myrcene-led terpene profile. Those two kinds of information serve different purposes: flavor tags describe reader impressions, while the terpene list summarizes the source's chemistry data. Neither identifies a particular sample. This entry retains the reported cross without treating it as genetically authenticated parentage.

Blueberry

Blueberry, also called Berry Blue, is associated with DJ Short's work beginning in the late 1970s. Leafly describes Thai-related ancestry and notes that material passed between breeders and seed banks over time. This history is a reason to preserve source and selection details rather than assume all Blueberry records describe one identical plant. Blueberry, berry and sweet are reader flavor descriptors; the fruit name alone is not a chemical measurement or proof of parentage.

Cannatonic

Cannatonic is a Resin Seeds cultivar associated with CBD-focused selections. The breeder identifies Reina Madre and NYCD as its cross; this differs from an older lineage still found in some catalogs.

Cheese

Cheese has roots in a British Skunk 1 selection. Leafly also describes later Afghani contributions, so these links represent family history rather than one universal cross.

Granddaddy Purple

Granddaddy Purple, often shortened to GDP, is associated in Leafly's account with Ken Estes and 2003. Its pedigree is less settled than that familiar name suggests: the source presents both a Mendo Purps/Skunk/Afghan account and a Big Bud × Purple Urkle account. This profile keeps that disagreement visible. Grape, berry and violet are reported flavor descriptors, not evidence that either proposed family tree has been confirmed.

Grape Ape

Grape Ape is associated with Apothecary Genetics and Barney’s Farm. Its reported background includes Mendocino Purps, Skunk and Afghani, without a fully specified crossing sequence.

Green Crack

Green Crack is listed by Leafly with names including Green Crush and Mango Crack. Its proposed background pairs Skunk #1 with an unidentified indica, leaving part of the pedigree unresolved. Citrus, mango and earthy are reader flavor descriptors on the source page. The dramatic name is a naming convention, not an ingredient statement, and the unknown parent should stay unknown rather than be replaced with a familiar strain to complete the tree.

Harlequin

Harlequin is cataloged as a sativa associated with CBD-rich selections. Leafly links its ancestry to Colombian Gold and Nepali, Thai and Swiss populations; sample chemistry still requires analysis.

sativa16
Haze

Haze is a broad sativa-associated family that Leafly places in Santa Cruz in the 1960s. Its account names Colombian, Mexican, Thai and South Indian ancestry without defining a complete sequence of crosses. The profile's spicy or herbal, tobacco and earthy tags describe reader impressions. This family-level history is useful when exploring descendants, but the word Haze in another strain's name is not enough to prove a direct parent relationship or identical chemistry.

Hindu Kush takes its name from the mountain region spanning parts of Afghanistan and Pakistan. This entry documents that regional background and the source's catalog traits without assigning an unsupported parent cross.

Jack Herer

Jack Herer is named after the author and cannabis activist. Leafly attributes its development to Sensi Seeds and describes a Haze hybrid combined with Northern Lights #5 and Shiva Skunk ancestry. The source acknowledges multiple phenotypes, which matters when interpreting the name as a single record. Its terpinolene-led catalog profile and pine, wood and earth flavor tags describe different evidence types, not a guarantee that every Jack Herer sample shares the same composition.

Lemon Kush

Lemon Kush has competing pedigrees: Master Kush with Lemon Joy, or the Alien Genetics version of Lemon G with Afghan Kush. These are alternatives, not a four-parent cross.
