In the 2010s, cannabis breeding took on a new character – exotic flavor profiles and flashy names became the trend, especially coming out of California’s scene. With legal markets emerging, breeders (and marketers) leaned into dessert, candy, and celebrity strain names to stand out. Many of these modern strains are descendants of the 90s/00s classics, but cross-bred for sweeter terpene profiles or stronger effects. Importantly, one lineage – the Cookies family – played a central role in this era. Here are some top strains of the 2010s and 2020s and their heritage:
Girl Scout Cookies (GSC)
Lineage: OG Kush × Durban Poison
The flagship “dessert” strain, GSC was created around 2010 in the Bay Area by the collective known as Cookie Fam (involving rapper Berner and breeder Jigga). Its genetics are OG Kush × Durban Poison – combining a potent West Coast indica with a pure African sativa. GSC is a THC powerhouse (20–28%) known for a sweet, doughy aroma with minty undertones (hence “Cookies”). It delivers a crushing euphoric high, deeply relaxing both mind and body, reflective of its indica dominance (~60% indica). After winning a Cannabis Cup and spreading through California’s dispensaries, GSC became the progenitor of an entire “Cookies” genetic line. This one strain “created the entire genre of Cookies genetics” in modern breeding. GSC’s success even led to the formation of Cookies as a lifestyle brand. Notably, GSC also carried over Durban Poison’s minor CBD/CBG content in some phenos, but mostly it’s prized for high THC.
Gelato
Lineage: Sunset Sherbet × Thin Mint GSC
A descendant of GSC, launched in 2014 by Cookie Fam in San Francisco. Gelato’s lineage is Thin Mint GSC × Sunset Sherbet. (Sunset Sherbet itself is GSC × Pink Panties, with Pink Panties being a Florida Kush). The result was a balanced hybrid (~55% indica) with a decadent sweet creamy flavor reminiscent of ice cream – hence the name Gelato. Gelato phenos (especially #33, nicknamed “Larry Bird”) gained fame for their gorgeous purple-orange buds and blissful high that’s both euphoric and relaxing. THC often tests in the mid-20% range. Gelato rapidly became “one of the most famous strains” of the 2010s. It has since spawned many variants and crosses (Gelato #41, #45, etc., and crosses like Gelato Cake, Ice Cream Cake). In particular, Gelato #33 × Zkittlez gave rise to Runtz (see below), showing Gelato’s importance in the family tree.
Zkittlez
Lineage: Grape Ape × Grapefruit
A candy-flavored indica-dominant hybrid, bred by 3rd Gen Family/TerpHogz in Northern California in the mid-2010s. Zkittlez (sometimes “Skittlez” or just “Z”) is Grape Ape × Grapefruit × an undisclosed third strain. In effect it’s a blend of a Purple indica (Grape Ape) with a tropical sativa (Grapefruit), resulting in a 70% indica strain that tastes like a bag of candy. Zkittlez won 1st Place Indica at the 2015 Cannabis Cups in San Francisco and Michigan, and the 2016 Emerald Cup, thanks to its unique terpene profile. It emits intensely fruity, sweet, berry and citrus aromas – often described as “grape candy” – yet still delivers a strong relaxing body high. Zkittlez was somewhat rare at first (TerpHogz kept tight control), but it quickly became a sought-after flavor. It’s the mother of several new strains, most notably Runtz.
Wedding Cake
Lineage: Triangle Kush × Animal Mints
A hugely popular dessert strain of the late 2010s. Wedding Cake’s genetics were long debated, but reliable sources indicate it comes from Triangle Kush × Animal Mints (Animal Mints itself being a GSC cross). Some dispensaries erroneously list it as GSC × Cherry Pie, but in fact Triangle Kush (an OG Kush varietal) and Animal Mints are the true parents. In any case, Wedding Cake carries a rich vanilla cake batter flavor with a hint of pepper, and sky-high THC often 25%+. It has a frosty, bountiful appearance (likened to cake frosting) and an indica-leaning knockout effect. This strain swept awards (Leafly’s Strain of the Year 2019) and became a staple for its relaxing yet euphoric high that can help with stress and appetite. By 2020, “Cake” strains proliferated (Birthday Cake, Ice Cream Cake, etc.), but Wedding Cake remains the crowd-favorite.
Runtz
Lineage: Gelato #33 × Zkittlez
A cross of Gelato #33 × Zkittlez, Runtz exploded onto the scene around 2017 in Los Angeles. Created by the Runtz Crew (Ray Bama, Nick, and rapper Yung LB in collaboration with Cookies brand), Runtz was phenohunted from those parent strains for an ideal mix of fruit candy terpenes and strong potency. It features a sugary-sweet aroma blending tropical fruit, berries, and creamy notes – often compared to the candy it’s named after. Runtz won Leafly’s Strain of the Year 2020, reflecting its massive impact in a short time. As a perfectly balanced hybrid (50/50), Runtz gives a joyful, giggly high before mellowing out into relaxation. Its buds are typically dense, brightly colored, and absolutely soaked in trichomes (THC 20–29%). Runtz’s hype led to many offspring/phenotypes: White Runtz, Pink Runtz, Apple Runtz, etc. It is a pinnacle of the “candy strain” trend, combining the best of the Cookies (Gelato) and Zkittlez lines into one all-star.
Other Notables (2010s/20s): Sunset Sherbet (Girl Scout Cookies × Pink Panties) – a fruity cookies hybrid that was parent to Gelato. Do-Si-Dos (OGKB GSC phenotype × Face Off OG) – a pungent, cookie-kush blend with high THC, named after another Girl Scout cookie. GMO Cookies (Garlic Cookies) – a 2010s cross of GSC × Chemdawg that oddly smells like garlic and fuel, illustrating the extremes of modern terpene selection. MAC (Miracle Alien Cookies) – a polyhybrid (Starfighter × Colombian × GSC) famous for its crazy frost levels and balanced euphoric high. Cherry Pie (GDP × Durban) – bridging the Purple and Durban families, gave a sweet cherry aroma and calming high, and itself led to Wedding Cake in some genealogies. On the CBD side, Charlotte’s Web (developed 2011) deserves mention for igniting interest in high-CBD, low-THC strains for medical use – though not directly in the THC lineage “family tree,” it represents a parallel branch where breeders reintroduced hemp genetics to boost CBD.
The 2010s also saw breeding techniques modernize: tissue culture, feminized and autoflower seeds (like Lowryder in 2002, an NL#2 derivative ), and lab testing for cannabinoids/terpenes all improved. This allowed precision in creating desired flavor or effect profiles. The result is that today’s popular strains often have very complex heritage. For example, a strain might be marketed as, say, “Tropical Runtz”, but its lineage could involve Runtz × (Pineapple Express × OG Kush) – stacking multiple generations of crosses.
Tracing Your Favorite Strain Up the Family Tree: From the above, you can see how current strains connect back to the classics. A modern “candy” hybrid like Runtz carries Gelato (which has GSC, which has Durban/OG Kush, which in turn has Chem and Hindu Kush), and Zkittlez (which has Grape Ape/Purple, which has Afghanistan; and Grapefruit, which links to Southeast Asian sativas). In other words, if you trace the lineage of almost any 2020s strain, you will end up at those original landraces – Thai, Afghan, Mexican, Colombian, etc. – within a few generations.
Understanding this family tree of cannabis helps appreciate how breeding innovation built upon past genetics. The landraces of the ’60s–’70s gave us the sturdy indicas and soaring sativas that, when crossed in the ’80s, produced well-rounded hybrids like Skunk, NL, and Haze. The ’90s hybrids combined those further into legends like White Widow, AK-47, and OG Kush. Those, in turn, were remixed in the 2000s and 2010s to create today’s trending strains like Wedding Cake and Runtz. New strains continue to emerge each year, but they’re nearly all descendants of the major genetic lines outlined above.
In summary, the cannabis family tree is both diverse and interconnected. From wild landraces to deliberately crafted hybrids, each era’s notable strains have left their genetic mark. Modern connoisseur strains can be traced back through decades of crosses – and while the complete genetic map is enormously complex, we can easily identify the key lineages and “family” groupings. This helps growers and enthusiasts trace the origins of their favorite buds and see how today’s candy-named super-strains are rooted in cannabis history.
