# Granddaddy Purple (GDP)

Granddaddy Purple, often abbreviated GDP, is a purple-leaning cultivar that became a visual and aroma staple on West Coast shelves in the 2000s. Dark coloration, grape-berry aromatics, and Kush-adjacent marketing made it a consumer favorite and a parent name in later purple dessert crosses. For many shoppers it was the first purple cultivar they could name.

Published parent stories frequently list Purple Urkle × Big Bud. Records conflict: some accounts emphasize different purple clone parents or unnamed Kush influence. Love The Plant treats deep pedigree as partly Unknown when sources disagree, while still noting the commonly taught cross so readers have a starting model.

Why GDP mattered: it cemented purple grape as a retail category and fed later candy and punch naming. On this live list, [Purple Punch](/strain/purple-punch) sits in related dessert-purple conversation (often discussed with Larry OG × Granddaddy Purple in many catalogs—confirm on that page). Kush neighbors include [Bubba Kush](/strain/bubba-kush), [OG Kush](/strain/og-kush), and Cookies-era dessert pages that sometimes borrow purple coloring without shared parents.

GDP is not automatically a Cookies or Chem child; keep family links contextual. Breeders used the name widely, so each GDP-labeled product needs its own parent check. [Wedding Crasher](/strain/wedding-crasher) connects punch and cake stories downstream without rewriting GDP's own disputed early tree.

Aroma education typically cites grape, berry, earthy sweet, and mild spice. Terpene names often mentioned include [Myrcene](/terpene/Myrcene), [Caryophyllene](/terpene/Caryophyllene), [Pinene](/terpene/Pinene), [Limonene](/terpene/Limonene), and [Linalool](/terpene/Linalool).
