Guava Cupcake (sometimes listed in retail markets as Guava Cupcakes) is a contemporary sativa-dominant hybrid cultivar bred by the Oregon-based cannabis genomics firm Phylos Bioscience. Developed as part of Phylos’s modern production-ready seed line, the variety is the progeny of a cross between Franken Cakes #46-O and Gorilla Diesel #21-O. In commercial settings, the strain has gained acclaim for its vigorous vegetative uniformity, short outdoor flowering window, striking development of pink stigmas in cooler outdoor climates, and a rich terpene profile combining tropical fruit, confectionery sweetness, pine, and pungent sourdough undertones.

Appearance
Guava Cupcake inflorescences present a tight, clustered calyx architecture with moderate tapering. Foliage generally exhibits bright forest and mint green shades, set against an abundant layer of glandular capitate-stalked trichomes that give the cured nugs a frosted, crystalline finish. One of the most documented visual characteristics of this cultivar is its tendency to produce vibrant pink and magenta pistils when cultivated in natural outdoor environments subject to diurnal temperature shifts. Under indoor lights or upon maturation and drying, these stigmas mature into deep amber and coral threads woven tightly across the floral bracts.
Aroma & Flavor
True to its culinary name, Guava Cupcake displays an intricate terpene profile centered around tropical fruit and sweet bakery aromas. The primary bouquet delivers punchy notes of ripe guava, sliced pineapple, and candied citrus, balanced by a distinct sweet pastry undertone reminiscent of frosted sponge cake. Upon breaking open or grinding the flower, deeper background notes of crisp woodland pine and fermented sourdough bread emerge, inherited from its Gorilla Diesel parentage. On inhalation, the smoke or vapor carries sweet, sugary fruit and subtle pastry dough, concluding on a palate of herbaceous pine and a faint, savory diesel funk on the exhale.
Terpene Profile
Analytical testing published by Phylos Bioscience identifies a total terpene concentration averaging around 1.6% by dry weight, while commercial batches from licensed processors have shown testing results ranging up to 2.28%. The dominant terpene profile is led by:
- β-Myrcene: Provides the foundation for sweet tropical fruit aroma and subtle physical comfort.
- D-Limonene: Introduces bright citrus tones and contributes to the strain’s crisp, mood-lifting aromatic finish.
- β-Caryophyllene: Adds warm, spicy depth and interacts with peripheral cannabinoid receptors.
- Secondary Terpenes: Linalool, α-pinene, β-pinene, and humulene appear in lower, measurable quantities, refining the floral and woodsy nuances of the cultivar.
Potency & Cannabinoids
Phylos Bioscience rates Guava Cupcake at a baseline target of 27% total THC, with an expected analytical variance of ± 2% (25% to 29%) under standard agricultural regimens. Commercial dispensary lots produced under state-licensed adult-use testing programs have reported cannabinoid measurements between 24.36% THCA and 30.45% to 32.0% total THC. Secondary cannabinoids appear in minor quantities, with typical certificates of analysis recording CBGA between 1.2% and 2.13%, along with sub-percentage trace amounts of CBG, CBC, and THCV. CBD levels consistently test at trace levels (less than 0.1% CBDA).
Effects
Consumer and industry reports describe subjective effects that vary significantly depending on dose, tolerance, and individual biochemistry.
Mental Effects
Consumers typically describe the onset of Guava Cupcake as swift, cerebral, and distinctly mood-elevating. It is widely characterized by a sharp rise in focus, daytime inspiration, and buoyant creativity without immediate cognitive clouding. Many users note feelings of giggly optimism, making it a popular choice for daytime socialization, active outdoor recreation, and creative projects.
Body Effects
While cognitively stimulating, Guava Cupcake maintains a gentle, functional somatic footprint. Physical sensations are generally reported as relaxing rather than immobilizing, releasing mild muscular tension without inducing heavy lethargy during the initial hours of consumption. When consumed in larger quantities or toward the end of its duration, the energizing onset tends to soften into mild physical tranquility.
Cultivation Characteristics
Guava Cupcake was engineered for high agronomic performance, particularly in outdoor and mixed-light facilities. Phylos explicitly notes that the cultivar demonstrates a medium vertical stretch during the transition to flower. When topped once or twice and given light canopy training, plants develop a remarkably tight and uniform vegetative canopy that facilitates efficient light interception.
The cultivar is classified as a short-season variety with a rapid flowering period of 7 to 8 weeks (approximately 49 to 56 days). This shortened maturation cycle makes it well-suited for temperate or northern outdoor growing zones where autumn rains and early frosts pose mold hazards. Phylos documents that the seed line has undergone stress screening for hermaphroditic tendencies, maintaining stable feminization and high germination rates (90%+ under controlled conditions). Yield potential is documented as medium to high. Note that while the strain excels under natural light and greenhouse installations, Phylos has formally noted that performance was not specifically validated in tightly closed artificial-light environments.
Resin & Extraction Characteristics
Guava Cupcake exhibits distinct gland morphology characterized by sandy, brittle trichome heads that separate cleanly during mechanical agitation. Phylos formally classifies the cultivar as suitable for washing, denoting its suitability for solventless ice water extraction (bubble hash) and live rosin manufacturing. Concentrate extractors in legal markets utilize the strain for both live resin sugar and hydrocarbon extracts, noting strong retention of its sweet guava, pineapple, and sour diesel terpene fractions through post-harvest processing.
Scientific & Botanical Overview
Taxonomically identified as Cannabis sativa L., Guava Cupcake represents an advanced F1 hybrid breeding project designed for commercial uniformity. By crossing distinct parental lines—Franken Cakes #46-O and Gorilla Diesel #21-O—breeders utilized marker-assisted breeding and genomics to stabilize high-yield traits, rapid photoperiod transition, and targeted chemotypic profiles. The cultivar’s signature pink floral stigmatic coloration is linked to localized anthocyanin expression in stigmatic tissue, triggered primarily by cool outdoor evening temperatures during late floral bloom.
Lineage & Related Strains
The genetic makeup of Guava Cupcake pairs two modern hybrid parent lines:
- Franken Cakes #46-O: A dessert-leaning selection that contributes bakery, sweet dough, and cake nuances along with tight calyx formations.
- Gorilla Diesel #21-O: A high-vigor, fuel-forward parent that introduces sour diesel aromatics, pine notes, and robust vegetative branching.
Related sister hybrids and crosses derived from similar parental pools include Pineapple Donut and Pineapple Cream Cake (Franken Cakes × Gorilla Diesel #3), which express analogous combinations of tropical fruit and confectionary flavors. Guava Cupcake should not be confused with Guava Cake, an unrelated indica-leaning hybrid typically tied to Wedding Cake or Gold Leaf lineages.
Sources & Data Notes
Data regarding Guava Cupcake is synthesized from primary technical documentation published by the breeder, Phylos Bioscience (including agronomic sheets and cannabinoid/terpene specifications), corroborated by state-mandated laboratory certificates of analysis from licensed cultivators and processors in Washington, Oregon, and Montana.
Guava Cupcake Summary
Guava Cupcake is a 27% THC sativa-dominant hybrid developed by Phylos Bioscience from Franken Cakes #46-O and Gorilla Diesel #21-O. Recognized for its tropical guava, sourdough, and sweet pine bouquet, it offers focused daytime effects, rapid 7- to 8-week flowering, distinct pink outdoor pistils, and sandy resin ideal for solventless washing.
