Field note N°140 · Strain review

London Pound Cake strain

In one line

London Pound Cake, or LPC, is an indica-leaning hybrid credited to Cookies. Leafly and Weedmaps list it as Sunset Sherbet crossed with a parent the breeder never named. Published profiles lead with beta-caryophyllene, then limonene and myrcene. As of October 3, 2026, THCA flower sold under the name can pass as hemp only where state law allows, and only until December 11, 2026.

Dense cannabis canopy seen from above

London Pound Cake (LPC) is an indica-leaning hybrid credited to Cookies, the California brand. Its listed pedigree is Sunset Sherbet crossed with a second parent that Cookies has never named, so half of its family tree is not on record.

The file

Field What is on record How solid
Credited breeder Cookies (Leafly, Weedmaps) Widely repeated
Parent 1 Sunset Sherbet (Girl Scout Cookies x Pink Panties, Mr. Sherbinski) (Leafly) Reported consistently
Parent 2 “Unknown heavy-hitting indica” (Leafly), “unknown hybrid” (Weedmaps) Undisclosed
Listed cut LPC 75 (Weedmaps) Listed; meaning of the number unpublished
Type Indica-dominant hybrid Menu convention
Lead terpene (published profiles) beta-Caryophyllene Varies by Batch
Next terpenes Limonene, myrcene Varies by Batch
Flowering time About 60 days, per Weedmaps Single source

Where the name comes from

The “pound cake” is about the dessert, not a quantity. It sits in the Cookies catalog next to another dessert name, Cereal Milk, and a non-dessert cut, Gary Payton. “London” has no documented origin story. Treat any tale about a London cut as folklore until the breeder says otherwise.

Weedmaps says the breeders have kept the full lineage confidential. Leafly and Weedmaps also disagree on how to describe the missing parent: “heavy-hitting indica” on one, “hybrid” on the other. Neither is a name, and neither can be checked.

LPC vs LPC 75

Weedmaps keeps a separate entry for London Pound Cake 75, credited to Cookies. A number after a strain name usually marks one selected phenotype kept as a clone, though nobody has published what 75 refers to here.

London Pound Cake London Pound Cake 75
Lineage listed Sunset Sherbet x undisclosed “Unknown” on Weedmaps
Aroma reported Lemon, citrus, berry, pine (Weedmaps) Gassy and sweet, blueberry, lemongrass, menthol over OG musk (Weedmaps)
Pedigree published by breeder No No

The two aroma write-ups barely overlap, which fits two phenotypes from one cross. If a menu says only “LPC,” the cut is unknown. If it names another number, ask the seller where that number comes from. The COA is the only document that describes the flower you are actually looking at.

What does it smell and taste like?

Leafly reviewers describe sweet and spicy flavor with diesel and nutty undertones, plus vanilla, butter and lemon notes (Leafly). Weedmaps users lean citrus: lemon, citrus and berry are the top three flavor tags, with pine mentioned in the description (Weedmaps).

The published terpene order fits part of that:

Terpene Typical aroma note Commonly reported role in LPC
beta-Caryophyllene Black pepper, spice Usually the largest share
Limonene Citrus peel The lemon top note
Myrcene Earthy, herbal, ripe fruit Supporting base

Vanilla and butter are not explained by those three. Compounds outside a standard COA terpene panel are a likely source of the cake side, though no published LPC analysis confirms which ones. Leafly lists the same three terpenes in the same order for Sunset Sherbet (Leafly). That is consistent with the profile coming from that parent, but it is also the most common order in dessert hybrids, so it proves little.

Reported effects

User reports on Leafly most often tag LPC as sleepy, tingly and relaxed (Leafly). On Weedmaps, 42% of effect tags say relaxed, 31% happy and 27% euphoric. Weedmaps describes “immediate cerebral effects” followed by a relaxing body high that can turn sleepy (Weedmaps). These are crowd-sourced tags, not measurements, and they come from dispensary flower rather than any specific hemp Batch. None of this is medical advice.

Grow and phenotype notes

  • Flowering: around 60 days, per Weedmaps. No breeder grow sheet is public.
  • Structure: Weedmaps notes dense buds with orange pistils and frosty, amber-colored trichomes.
  • Cuts vs seeds: a selected cut such as LPC 75 is kept alive as clones. Any plant grown from seed, even from an LPC cross, is a new phenotype and not that cut.
  • Color: purple coloring shows up in some photos and not others. It depends on phenotype and night temperatures, not potency.

How LPC shows up as THCA flower

In the hemp lane, the strain name is a claim the seller makes, and the COA is the evidence. Check these before you trust the name:

  • Batch code on the COA matches the bag.
  • Delta-9 THC is at or below 0.3% by dry weight, the hemp test in force as of October 3, 2026.
  • Total THC is reported. 7 CFR 990.25 requires federal hemp tests to reflect THC plus THCA; labs commonly calculate delta-9 + (THCA x 0.877).
  • Terpene panel names individual compounds. For LPC, caryophyllene near the top is consistent with the published profile. A limonene-free panel is a reason to ask questions.
  • Cut named, if the seller claims LPC 75. Ask how they know; a clone source or grower statement is the only documentation that exists.
  • Lab credentials: ISO/IEC 17025 accreditation and a sample ID you can verify on the lab’s own site.

Federal law today defines hemp by delta-9 THC alone, at 0.3% or less on a dry-weight basis (7 U.S.C. 1639o). That is how high-THCA flower is sold as hemp. Several states have already closed that route for flower.

Section 781 of P.L. 119-37 moves the federal test to total THC, including THCA. H.R. 6500 was signed September 2, 2026 and set December 11, 2026 as the date that applies to naturally occurring cannabinoids such as THCA (enrolled text, Sec. 2019). CRS IF13136 covers the original section 781 change. After that date, any LPC flower with a typical THCA reading fails the hemp definition.

Asked at the desk

What is London Pound Cake a cross of?

Leafly and Weedmaps both list Sunset Sherbet crossed with an undisclosed parent, usually described as a heavy indica. Cookies has not published the second parent, so any name you see for it is a guess.

What does LPC 75 mean?

In cannabis naming, a number after a strain name usually marks one selected phenotype kept as a clone. Weedmaps lists London Pound Cake 75 as its own entry under Cookies, but no public source explains the number. Treat LPC 75 and plain LPC as possibly different plants, and read each Batch COA separately.

Is London Pound Cake indica or sativa?

Menus list it as an indica-dominant hybrid. That label says little about chemistry. The terpene panel on a COA tells you more than the indica or sativa tag.

Is London Pound Cake THCA flower legal?

As of October 3, 2026, it can be sold as hemp if it tests at or below 0.3% delta-9 THC and the buyer's state permits hemp flower. From December 11, 2026, federal law counts THCA toward total THC, and high-THCA flower stops qualifying as hemp anywhere in the US.
