15 Highest-ROI Crops
Passionfruit returns $20x its seed cost. These crops are ranked by gross harvest value divided by seed cost, using USDA yield and price data.
How the Ranking Works
ROI ratio = (average yield × retail price per lb) ÷ seed cost. A ratio of 10x means a $3 seed packet produces $30 in harvest value. This measures return per dollar invested in seed, not return on total garden inputs. For the full cost picture including soil, water, and labor, see the methodology page and raised bed break-even analysis.
Yield data is sourced from USDA extension research and land-grant university trials. Retail prices are from USDA AMS and ERS reports. All figures represent seasonal averages across US growing regions.

What This Table Doesn't Show
ROI ratio measures seed cost efficiency only. It doesn't account for:
- Space efficiency - a high-ratio herb like basil yields less total value per square foot than a high-yielding tomato crop
- Time to harvest - asparagus has a 3-year establishment period before meaningful yield
- Difficulty - some high-ROI crops require specific soil conditions, zone compatibility, or pest management
- Your actual consumption - the highest-ROI crop is the one you'll eat; 10 lb of an herb you don't use is worthless
