Harry Palms built his reputation at Oni Seeds — Tropicanna Cookies, Papaya, a catalog of crosses that consistently prioritized terpene complexity and resin production over trend-chasing. When he left to found Bloom Seed Co. in Colorado, he brought that same orientation with him. Black Maple is one of the results: Dulce de Uva crossed with Sherbanger 22, a combination that puts grape-forward sweetness directly against the spicy, gas-heavy punch of the Sherbanger lineage and produces something that lands in its own terpene territory.
Dulce de Uva — Spanish for sweet grape — contributes exactly what the name suggests: a rich, dark grape sweetness that sits at the base of the profile and gives the whole cross its candy-fruit foundation. Sherbanger 22 brings the other half: a Sherbert-adjacent cross with a Banger lineage that adds gassy fuel undertones, spice, and the resin architecture that makes Sherbert-family genetics a reliable breeding donor for growers who want frost and potency alongside flavor. The combination produces the maple syrup and caramel sweetness that gave Black Maple its name — a dessert-forward profile that reads rich and warm rather than sharp or fruity, with a woody spice note underneath it and a rubber and black pepper quality in the background that keeps it from being purely sweet.
The #22 designation is the pheno hunt. Black Maple ran as a population and plant number 22 was the expression that stood apart — the specific convergence of terpene intensity, resin coverage, and visual presentation that earned it a numbered designation and its own identity. It swept the 2023 Oregon Cannabis Cup alongside Lemonhead Delight and Candy Fumez, a competition win that put it on radars nationally and confirmed what the growers who had been running it already knew.
In the garden Black Maple #22 expresses deep forest green to dark purple coloration with dense, sticky, high-calyx-density buds that photograph well and cure even better. Trichome coverage is heavy — Bloom Seed Co. genetics consistently prioritize extraction-quality resin output, and the #22 delivers high-density capitate-stalked trichome coverage that washes cleanly and retains the maple-caramel terpene profile through the extraction process. Flowering runs approximately 63 days. Effect is euphoric and well-balanced at onset, shifting into warm, thorough body ease as the session develops.
