The Story Behind the Top 5
Runtz
Runtz is a Zkittlez x Gelato cross that came out of California and became one of the most recognized candy strains in the country. Its sweet, fruity aroma and colorful buds made it an easy name for Illinois shoppers to remember. Read about one parent in our Zkittlez review.
Cookies
The Cookies family traces back to Girl Scout Cookies, usually listed as OG Kush x Durban Poison. Its sweet dough and light gas profile shaped a whole generation of dessert strains. Our Girl Scout Cookies review covers the original.
Gelato
Gelato is a Bay Area cross of Sunset Sherbet and Thin Mint Girl Scout Cookies, known for creamy dessert and citrus notes. It is also a parent of Runtz, so two of the top five cannabis strains in Illinois share the same family.
MAC
MAC, short for Miracle Alien Cookies, is credited to Capulator and is known for its funky cream and citrus aroma and a very frosty look.
Blueberry
Blueberry is the elder statesman of the list, a 1970s-era line credited to DJ Short. Its sweet berry aroma has kept it on shopping lists for decades.

Illinois Outlook
Illinois is building a regional identity: Midwest favorites give locals something to champion, while national hitters like Permanent Marker keep the state tied to the bigger trend cycle.
What the Risers Have in Common
The fastest-rising Illinois strains share a few traits: candy and berry aromas, loud gas and heavy frost. Permanent Marker, credited to Seed Junky Genetics and built from Biscotti and Jealousy, pairs gas with sweet dough. Blockberry brings sweet berry over a light gas base and gives Midwest shoppers a name with local pride behind it.
Kush and Cream, Girls Best Friend and Grape Bubblegum round out the list with creamy, fruity and grape-candy profiles. Taken together, the risers show Illinois tastes moving toward bold, unmistakable aromas.
How Illinois Tastes Compare to the Rest of the Midwest
Illinois opened adult-use sales in January 2020, and its market has grown into one of the largest in the Midwest. That size makes it a useful barometer for the region.
The pattern in Illinois strains looks familiar across the Midwest: a strong base of dessert classics, with new interest in gas-heavy and candy-forward lines. What sets Illinois apart is the attention on regional names like Blockberry, which gives local shoppers something to champion alongside the national hits.
Building an Illinois-Themed Collection
For adults 21+, cannabis strains in Illinois make a strong regional theme. One approach is to pair a classic from the top five with a riser that shares its family, such as Gelato next to Runtz, or Girl Scout Cookies next to Permanent Marker.
Another approach is to collect by aroma: one candy strain, one dessert strain, one gas strain and one berry strain. Either way, keep sealed original breeder packs and note the breeder and lineage of each.
