London Pound Cake, also written London Poundcake and shortened to LPC, is a Cookie Fam Genetics hybrid with one confirmed parent and one the breeder never named. The documented cross is Sunset Sherbet with an undisclosed second parent. Roughly 70% indica by the usual reckoning, dense and heavily frosted.
Where It Comes From
LPC came out of the Cookie Fam ecosystem in California, the same collective behind Sunset Sherbet itself. Sunset Sherbet traces to Girl Scout Cookies crossed with Pink Panties, which puts London Pound Cake two steps from the GSC line that reorganized American dessert cannabis in the 2010s.
The second parent has never been published. Cookie Fam kept it proprietary and left the blank exactly where it is, and no listing that fills it in is working from anything the breeder released.
What is documented is the outcome: heavy structure, a slower physical finish, and a plant that other breeders reached for constantly once it started circulating. That last part is the reason the name outlasted its era rather than rotating off menus with the rest of the 2010s dessert wave.
The Cross
Breeder: Cookie Fam Genetics. Confirmed genetics: Sunset Sherbet x undisclosed indica. That is the whole verifiable pedigree.
Where LPC's record is genuinely deep is downstream. It appears as a parent in 91 catalogued crosses, including Animal 75 with Animal Cookies, Cake Mix with Wedding Cake, Candy Rain with Gelato, Blueberry Bubble Gum with Runtz, and Candy Brain with Candyland.
Ninety-one documented crosses is the real measure of a breeding parent. Not a slogan, a count. The California dessert branches keep folding back into each other, which is why menus feel repetitive: Jealousy descends from the Gelato side, London Pound Cake from the Sherbet side, and both trace to the same Cookies root.
Flower is commonly dense and heavily frosted, often with purple shading. Purple is frequent in LPC but is not diagnostic. It tracks phenotype and growing temperature, not identity, and a green LPC is still an LPC.
What It Left Behind
Its influence is breeding rather than trophies, and it does not need the inflation. A strain that shows up as a parent in 91 documented crosses has already made its case.
Commercial bag appeal plus a profile broad enough to pair with gas, candy, fruit, or mint made it one of the more useful California parents of its era. Breeders reach for a plant like that because it does not fight whatever it is crossed into.
The High Rise Take
One named parent, one permanent blank, and a downstream family tree that explains half of a modern dessert menu. If this direction lands for you, follow it through the LPC crosses rather than the rumors about its missing parent.
