Zyrup is a hybrid from Growing Pains, the Michigan cultivator that calls itself a team of flavor makers. The company describes Zyrup as a timeless classic in its lineup, and the strain has become a working breeding parent inside the house program, feeding at least three newer Growing Pains releases.
Michigan menus have listed Zyrup flower at 27.17% and 27.8% THC.
Gelato and Zkittlez behind the cross
Growing Pains' dedicated Zyrup page lists the cross as Gelato × Zkittlez, pairing Gelato's impact with Zkittlez's sweetness. The company's full strain list adds a third house parent to that pairing, the same three-way build it uses for Bolo Runtz, an indica-leaning Growing Pains strain.
Gelato comes from Sunset Sherbet crossed with Thin Mint Girl Scout Cookies. Its numbered cuts include Gelato #33, nicknamed Larry Bird after the basketball player's retired jersey number, along with #41 and #45.
Zkittlez traces to Grape Ape and Grapefruit with a third strain, first developed by a grower known as Gas Station Bob. Terphogz popularized it in the 2010s with help from Brandon Parker of 3rd Gen Family.
Zkittlez took first place at the 2016 Emerald Cup and placed at Cannabis Cups in San Francisco and Michigan. Terphogz renamed it The Original Z in 2023 after a trademark settlement with a candy company.
Close relatives of Runtz and Zangria
The same two parents made Runtz, the Cookies Fam cross that Leafly named its 2020 Strain of the Year. The Runtz crew behind it was led by Yung LB of Long Beach, and at least 20 variations of Runtz now circulate worldwide.
Zyrup also has a Zkittlez sibling on its own menu. Growing Pains builds Zangria from Thin Mint Cookie × Zkittlez and pitches it as a nighttime strain. Zangria then became a parent itself, crossed with Gary Payton to make Znickerdoodle.
A parent inside the Growing Pains program
Zyrup's clearest mark is in what came after it. Growing Pains lists Banana Taffy as Honey Banana crossed with Zyrup and calls it one of the standout selections from the company's first in-house breeding project.
Two more crosses use numbered Zyrup selections. Kerosene Candy pairs Burnout O.G. with Zyrup 37, and Petrol Fumez pairs Burnout O.G. with Zyrup 32. Running two numbered keepers through separate crosses shows how much weight the program puts on the strain.
Both of those crosses use Burnout O.G., another house strain, as the other parent. Growing Pains also sells Burnout OG on its own, and King of Budz in Monroe has stocked it as a 3.5g prepack.
Zyrup on Michigan shelves
Growing Pains sells flower, jars, pre-rolls and rosin, and Zyrup flower turns up on menus across Michigan. Exclusive in Kalamazoo has carried the flower at 27.17% THC. King of Budz in Monroe has sold it by the ounce from its deli counter at 27.8% THC for $169.
King of Budz singles out Zyrup and Starburst OG as examples of the brand's approach, which pairs growing technique with sought-after genetics. Jane files Zyrup as a hybrid under the shorthand Gelato × ZKZ.
Built for candy fans
Growing Pains markets Zyrup squarely at candy enthusiasts, with bubblegum up front and a little gas behind it. The company positions it as an evening strain, describing a relaxed, euphoric high with a cozy couch-lock finish.
The founders started growing in tents in their basements before scaling into a commercial-size warehouse and entering the state's legal market. Every batch still goes through an R&D process that they oversee. Zyrup shares the menu with Honey Banana, Hi Chew and Citronade.
