Haven Greens, Canada’s first fully automated greenhouse, located in King City, Ontario, is introducing Trillium Blend, a Costco-exclusive product that highlights the best of Ontario.

Named after Ontario’s official flower, the blend represents freshness, strength and local pride. A medley of baby green leaf, baby red butter leaf, arugula, and mustard greens, the new product offers consumers a signature Ontario blend they can recognize and trust — grown locally, with care, for consistent taste and quality.

Like all their leafy greens, Trillium Blend is grown locally in the Greater Toronto Area within Haven Greens’ five-acre greenhouse—a touchless, climate-controlled and pesticide-free facility. This careful handling ensures that every pack maintains unparalleled quality and freshness. Currently on track to reach net-zero operations by 2027, the state-of-the-art greenhouse reflects Haven Greens’ commitment to innovation and providing an optimal consumer experience. Its unique growing approach means that its greens are ready-to-eat without washing and have an extended shelf life of up to five weeks, far exceeding the two-week shelf life of field-grown options.

Haven Greens officially launched earlier in 2025, with its first harvest taking place in March. Since then, the brand has grown significantly and expanded to retailers across the province and beyond. This new Costco partnership illustrates Haven Greens’ continued commitment to making its high-quality leafy greens widely accessible. 

The facility currently produces approximately 10,000 pounds of lettuce per day, totaling 3.6 million pounds annually. Its indoor, climate-controlled, and fully automated growing conditions allow for daily harvesting and year-round availability, giving Ontarians continuous access to Haven Greens’ fresh, locally-grown lettuce regardless of the season.
