What We're Growing

The plots, the plants,
the honest verdicts.

Every article is built from field notes, not speculation. When something fails, we write about that too — usually with more detail.

Seed Reviews

What the catalogs
don't tell you.

Every review is from seed sourced, grown, and eaten. Ratings reflect germination, yield, flavor, and disease resistance — in that order.

Baker Creek

Dragon Tongue Bean

4.7/5

Exceptional germination (94% in our tests), vigorous growth, and genuinely superior flavor to standard yellow wax. The streaking disappears on cooking, which nobody mentions.

HeirloomHigh YieldTested 3 Seasons
Johnny's Selected Seeds

Jasper F1 Tomato

4.2/5

The disease resistance package is real — we saw zero early blight while adjacent heirlooms struggled. Flavor is good for a hybrid, not transcendent. Worth growing for reliability.
