Where Blue Widow Comes From
Blue Widow crosses two famous parents, Blueberry and White Widow. AllBud credits the Spanish seed bank Dinafem with creating it and notes an Aloha male in the cross. It lists the aliases White Berry, Blue Venom and Berry White. Leafly does not name a breeder, so the attribution is only partly confirmed.
Because many growers sell versions of Blueberry crossed with White Widow, jars labeled Blue Widow can vary by producer.
Blue Widow Effects: What It Feels Like
Leafly readers most often report relaxed, euphoric and happy effects, and AllBud adds giggly and focused. The description says it offers both uplifting and calming sides, with drowsiness possible at higher doses.
THC is moderate, with Leafly listing around 14%, so it suits people who want a gentler experience. It works for an afternoon or evening, and a larger dose can lead toward sleep.
Blue Widow Terpenes, Aroma and Flavor
The aroma is sweet blueberry with hints of sour citrus and pine. Flavors are blueberry and berry sweetness. Leafly reports myrcene as the lead terpene, followed by pinene and terpinolene.
Buds are dense, with blue and purple tints, orange hairs and a sugary coat of crystals.
- Myrcene: earthy, musky and herbal, also found in mango and hops
- Pinene: fresh pine, also found in pine needles and rosemary
- Terpinolene: fruity, piney and herbal, common in classic sativas
Terpene levels vary from grower to grower and batch to batch, so check the lab label on the package. Learn more in our guide to cannabis terpenes.
