Gumosa is a Xeno Seed Company cross of Black Bubblegum #33 and Mimosa, selected as a phenotype by Bosky Genetics and sold as California flower. Bosky's grow of it took second place for flower at the 2025 MJBowl, and Xeno put seeds out after the result.
Flower runs dense and colorful — green and purple foliage, orange pistils, visible trichome coverage. Bosky sells the selection as a sativa and it reads bright rather than heavy.
Where It Comes From
This is a recent, well-documented release rather than an old cut with a murky origin. Xeno Seed Company is an independent breeder based in Richmond, California, and Gumosa came out of its Black Bubblegum program, crossed to Symbiotic Genetics' Mimosa.
The break came through cultivation rather than the seed catalog. Bosky Genetics grew the selected phenotype, entered it and placed second for flower at the 2025 MJBowl. The seed release followed the placement rather than preceding it, which is the reverse of how most new names reach growers.
The Cross
Xeno bred it. Bosky selected and grows the commercial cut. Keeping those two roles separate explains most of the confusion around the name.
The parents are stable even though menus write them in either order: Mimosa and Black Bubblegum #33, with the #33 specifying which Black Bubblegum selection sits behind the release. Mimosa is credited to Symbiotic Genetics and documented as Clementine crossed with Purple Punch, roughly a sixty-day flower. Black Bubblegum supplies the other half — darker candy sweetness, color and resinous funk.
Because Gumosa moves as seed as well as a selected cut, expression shifts between plants and between harvests. Cultivation, harvest timing, dry, cure and storage move the result more than most people expect, so the cultivator on the package matters as much as the name on it.
What It Left Behind
The result is specific: second place, flower, at the 2025 MJBowl, grown by Bosky Genetics from Xeno's Gumosa. That is the whole competition record, and it is more than most young names can show. Keep it separate from unrelated products using similar bubblegum or Mimosa names on a shelf.
The High Rise Take
A Richmond-bred citrus-and-candy hybrid with one placement behind it and a clean split between who bred it and who grows it. Check the label for both names before you buy.
