Compare the 11x7 Poppy and 12x7 Zalie cedar greenhouses to decide which size and layout fits your backyard garden and growing goals.
Quick answer
Choose the 11x7 Poppy if you want a trellis roof for hanging baskets and climbing vines; choose the 12x7 Zalie if you prioritize a clean sloped roof and slightly more interior floor space for year-round growing.
Size and layout: what 11x7 vs 12x7 really means
The Poppy measures 11 feet by 7 feet, while the Zalie measures 12 feet by 7 feet. That extra foot of length in the Zalie translates to more usable bench or bed space along the long walls, which matters if you plan to grow in rows or need room for a potting bench.
Both greenhouses share the same 7-foot width, so the difference is mainly in length. The Poppy's three-sided trellis roof extends outward, adding vertical growing space without increasing the footprint. If your site is tight on length but you want to grow upward, the Poppy's design may be more efficient.
Roof design: trellis vs sloped
The Poppy features an extended three-sided trellis roof that gives you room to hang baskets, trail plants, and train climbing vines along the roofline. This suits gardeners who want to use vertical space and create a lush, layered look.
The Zalie has a sloped roof with clean architectural lines. A sloped roof sheds rain and snow more effectively and provides a more traditional greenhouse appearance. It also offers uninterrupted headroom along the center, which can be helpful if you install tall stakes or hanging pots inside.
Insulation and glazing: same performance, different priorities
Both greenhouses use 10mm 4-wall polycarbonate panels with an R-2.1 insulation value, which improves heat retention by 30% over standard 6mm twin-wall. They also both have FSC-certified, kiln-dried cedar frames that resist rot, decay, and insects.
Because the glazing and frame materials are identical, your choice between the two comes down to size and roof style rather than thermal performance. If you need maximum heat retention, both are equally capable; if you need more space, the Zalie's extra length gives you more volume to buffer temperature swings.
Decision rules for choosing between Poppy and Zalie
- If you want to grow vertically: Choose the Poppy 11x7 for its three-sided trellis roof, which lets you hang baskets and train vines along the roofline. Measure the height and reach of your climbing plants to ensure the trellis suits your varieties.
- If you need maximum floor space: Choose the Zalie 12x7 for its extra foot of length, giving more room for benches, beds, or a potting area. Check that your site allows the additional length without crowding paths or doors.
- If you prefer a traditional look: Choose the Zalie's sloped roof for clean architectural lines and effective rain and snow shedding. Consider local snow loads if you live in a snowy climate; a sloped roof is generally better at shedding snow.
- If you want identical thermal performance: Both use the same 10mm 4-wall polycarbonate with R-2.1, so base your decision on size and roof style, not insulation. Plan supplemental heating or ventilation based on your climate, as both have the same insulation value.
