Cannalope Haze

Cannalope Haze is described by Leafly as Original Haze combined with a Mexican landrace. Original Haze links to the existing Haze profile; the unspecified Mexican material remains an external ancestry label. The regional reference does not justify choosing a particular Mexican cultivar as its parent.

Chem Sis

Chem Sis, also called Chem's Sister, is described by Leafly as a Chemdawg phenotype. This page records that selection relationship, helping explain its appearance in other reported families. The identity does not establish a new cross or guarantee uniform chemistry across products.

Chocolate Thai

Chocolate Thai is described by Leafly as a Thai landrace name associated with historical imports. The source also questions whether present-day offerings preserve the original material. Its coffee and tobacco reader tags describe impressions, not evidence of historical authenticity.

ECSD

ECSD is listed separately by Leafly as East Coast Sour Diesel. The reviewed narrative describes its identity and sensory character without establishing a complete parent cross. This page keeps that named line distinct from the broader Sour Diesel profile and leaves unsupported parentage unresolved.

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.

Hawaiian

Hawaiian is a sativa catalog entry with tropical and citrus flavor reports. The reference used here does not identify a named parent cross, so its ancestry remains open rather than inferred from the name.

sativa14
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.

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.

Jack's Cleaner

Jack's Cleaner is associated with Subcool's The Dank in Leafly's account. The source names Jack Herer and The Cleaner as the direct cross, then describes a more distant background for The Cleaner. This page keeps those levels separate instead of turning all ancestral names into direct parents.

Lemon G

Lemon G is associated by Leafly with Ohio and descent from Original G13. The source does not establish a complete two-parent cross, so the G13 link is recorded as ancestry. A lemon aroma alone is not used as evidence of a measured limonene concentration.

Malawi

Malawi is presented by Leafly as a sativa landrace associated with the Salima region of Malawi. A regional landrace identity is recorded without inventing a two-parent cross or treating every modern sample as identical.

Purple Thai

Purple Thai, also called Oregon Purple Thai, is described by Leafly through Highland Oaxacan Gold and Chocolate Thai. This profile preserves both named connections and helps contextualize Blueberry's reported ancestry. Regional and historical names still require provenance evidence before they can authenticate present-day material.

Raspberry Cough

Raspberry Cough is attributed by Leafly to Nirvana Seeds and a pairing of Cambodian landrace material with ICE. The Cambodian reference remains regional, while ICE remains a named external parent. The berry name and reader flavor tags do not identify a particular ancestral accession.

Strawberry Cough

Strawberry Cough is a sativa-classified catalog entry whose source describes its origins as uncertain while proposing Haze and Strawberry Fields as a possible cross. The proposed relationship therefore remains an attributed hypothesis rather than settled ancestry. Strawberry, sweet and berry are displayed reader flavor tags. Neither the fruit name nor the word Cough is a test of chemical identity, a measure of safety or proof that another similarly named sample is the same plant.
