The question most gardeners never ask is: of everything I could plant in this bed, what returns the most money? Not just “does it pay off” but “does it pay off better than the alternatives?”
That question has a quantitative answer. This ranking uses the yield and price data from each crop’s encyclopedia entry to compute net return per planting unit and net return per square foot. Every figure in the table below is traceable to a crop page on this site, which in turn cites USDA ERS retail price data. Nothing is invented.
How the Rankings Work
The core formula is: (avg_price_lb × avg_yield_lb) - start_cost = net return
All three inputs come from plant frontmatter fields:
avg_price_lb- retail price per pound, sourced from USDA Agricultural Marketing Service terminal market reportsavg_yield_lb- typical yield per planting unit (one transplant, one seed packet, or one batch of seed garlic)start_cost- what you pay to start one planting unit
The result is net return per planting unit before your own labor.
For the second column - net per square foot - a space footprint was added for each crop using standard spacing recommendations from Penn State Extension and Cornell Cooperative Extension. Transplants get the space one plant occupies at recommended in-row and between-row spacing. Seed packets get the space a typical home-scale planting uses.
Three crops in the table carry an asterisk: lettuce, arugula, and basil. For these, the frontmatter avg_yield_lb represents a single cutting cycle rather than full-season production. Their actual per-square-foot return over a full season is 5-10x higher than the table shows. This is addressed after the table.

The Top Performers
Cherry Tomato: The Clear Winner
Cherry and grape tomatoes (Solanum lycopersicum var. cerasiforme) occupy the top rank by a wide margin because they combine a high retail price ($3.00-4.50/lb per USDA AMS data), exceptional yield from a single plant, and a harvest window that runs from early summer to first frost. The 12 lb per plant figure in the table is a realistic midpoint for an indeterminate variety given adequate support and a full season. Plants like Sun Gold, Sweet Million, and Black Cherry regularly exceed it.
The cherry tomato’s advantage over slicing tomatoes is the price premium. Retail cherry tomatoes run roughly double what standard slicers fetch per pound. That premium more than compensates for the slightly lower per-plant weight, and the longer harvest window (indeterminate cherry tomatoes start producing 10-15 days earlier than most slicers) adds to the overall season return.
At $9.63 per square foot, cherry tomatoes outperform every annual vegetable in this table. The next closest at the same planting density - slicing tomato at $3.58/sq ft - earns less than 40% of that return.
The catch: cherry tomatoes still need staking or caging (a cage or stake adds $2-5 amortized over several seasons), consistent watering to prevent blossom end rot and fruit cracking, and a 60-80 day commitment before first harvest. They are not a beginner’s fastest payback - that distinction belongs to arugula and lettuce. They are, however, the highest ceiling.
Tomato and Hot Pepper: The Other Transplant Crops
Slicing tomatoes and hot peppers rank 2nd and 3rd per square foot, which reflects the advantage transplant crops have over seeded crops: you buy a plant already 6-8 weeks into its life, and the per-plant yield is known, not estimated across a mixed stand.
Hot peppers (Capsicum annuum) are frequently underrated in ROI discussions. The $3.49/lb retail price is for standard hot peppers; specialty varieties at farmers markets and farm stores routinely fetch $5-8/lb. At standard pricing, 3 lb from a $3.50 transplant occupying 2 sq ft returns $3.49 per square foot. If you grow specialty or heirloom varieties at a premium price point, that number improves substantially.
Hot peppers also have a secondary yield benefit: a mature plant at the end of the season can be dug up, root-pruned, potted, and overwintered indoors as a “pepper tree” that resumes production the following season. This effectively halves the start cost in Year 2 and beyond. An established 2-year-old pepper plant, having already paid for itself, has zero amortized start cost going forward.
Garlic: The High Absolute Return Crop
Garlic (Allium sativum) ranks 4th by net per square foot at $3.41. It earns the 4th slot despite having the highest absolute start cost in the table ($12 for seed garlic) because yield and price both work in its favor: $4.99/lb at the retail counter - a figure USDA AMS Specialty Crops data supports consistently - multiplied by 6.5 lb from one home purchase produces $32.44 gross. Net of the $12 seed investment: $20.44.
The nuance with garlic economics is timing. You plant in fall (October-November in most zones) and harvest the following July. The return on your $12 seed investment takes 9 months to materialize. That’s not a liability unless you’re treating it as a quick-turnover crop. Treated correctly - as a plant-and-forget fall investment that delivers in midsummer - it returns better per square foot than most crops in the second half of the table.
Seed garlic can also be held over from your own harvest, which eliminates the $12 start cost in Year 2 and beyond. Save 15-20% of your best heads for replanting. After the first year, garlic’s start cost drops to zero. See garlic ROI analysis for the multi-year breakdown.
Cucumber: Overlooked Middle Tier
Cucumbers (Cucumis sativus) land at 5th place and tend to be underestimated in ROI discussions because the per-pound retail price - $1.78/lb per USDA AMS - looks modest. What carries cucumbers is yield. A single plant on a trellis, given warm conditions and regular harvesting, produces 8-12 lb through the summer. At 2 plants from a $3.00 seed packet and 6 sq ft of trellised space, the math improves to $1.87 per square foot. Without trellising, cucumbers sprawl over 15-20 sq ft per plant and their per-sq-ft return collapses. Trellis them.
Pick every 2-3 days at peak production. Cucumbers left on the vine past maturity signal the plant to stop producing. Missed harvests directly reduce your return.
Kale and Spinach: The Cut-and-Come-Again Pair
Kale (Brassica oleracea var. acephala) and spinach (Spinacia oleracea) tie at $1.81 per square foot and both benefit from the same property: repeated harvest from a single planting. A kale plant harvested correctly - outer leaves taken, center left to continue growing - produces for 3-5 months from spring through fall. Spinach, faster-growing at 37-50 days to maturity, completes its cycle sooner but can be succession-planted across the same bed for continuous production.
The $3.50/lb retail price for kale reflects grocery store organic bunches (USDA AMS Specialty Crops Terminal Market data, 2024). Loose-bunch kale at a farmers market runs $4-6/lb. If you’re comparing against what you’d actually buy, the value per pound is closer to $4.
Kale is also one of the most cold-tolerant vegetables in this table, surviving into mid-fall and even winter under row cover in Zones 6-7. A spring planting that runs through December effectively doubles the season compared to a frost-sensitive crop. That extended window affects the real-season return but not the single-cycle frontmatter math in the table.
The Asterisk Crops: Where the Table Understates Reality
Lettuce, arugula, and basil show low per-sq-ft numbers in the main table because their avg_yield_lb in the plant data represents a single cutting cycle, not full-season production. For all three, the per-square-foot economics are better than the table suggests.
Arugula (Eruca vesicaria ssp. sativa) is the fastest payback crop in the garden by days-to-harvest - 30-40 days from seed to first cut. A single 3 sq ft planting yields 0.25-0.5 lb per cutting at baby-leaf stage, with 2-3 additional regrowth cuts before quality declines. One seed packet contains enough seed for 8-10 successive sowings through spring and fall. At $8/lb retail and 1.5 lb per succession across 3 cuts, a packet that costs $2.50 returns $12/succession × 9 successions = $108 in annual value from a rotating 3 sq ft. The table’s $0.50 figure reflects one cut from the first sowing. The real annual number, managed as a relay planting, is closer to $36/sq ft. See the arugula growing guide for succession timing.
Lettuce (Lactuca sativa) follows similar logic. Baby leaf lettuce from a broadcast sowing yields 1-1.5 lb per cut, with 2-3 cuts per sowing and 8-9 sowings per season from one packet. The $2.75 single-cycle net understates a managed relay planting by roughly the same factor.
Basil (Ocimum basilicum) is different in one important way: a single seed packet returns modest direct value, but basil propagates from cuttings with near-zero cost. One purchased plant or packet becomes the source material for dozens of free additional plants. The economics of basil are better analyzed as a propagation problem than a seed-packet problem. See herb ROI comparison for the per-herb propagation math and herb propagation from cuttings for the mechanics.
Beginner Shortlist
If you’re new to food gardening and want the highest probability of a positive return on the first attempt, three crops cover that case better than any others:
Cherry tomatoes. One transplant from a garden center, staked or caged, watered consistently, and harvested daily at peak - this is the single highest-returning food plant a beginner can put in a pot or a bed. You spend $3.50 on the transplant and $5-8 on a cage. Everything else is labor.
Kale. Forgiving of poor soil, cold-tolerant, and productive for months. Direct-seed or transplant in spring, harvest outer leaves continually, and a single packet delivers all season. Fewer failure modes than tomatoes.
Snap peas. Direct-sow in earliest spring (soil 40°F+), provide a simple trellis, and they produce in 55-70 days. Fast feedback for new gardeners, and $4/lb retail means even a modest harvest is worth counting. The plants die on their own when summer heat arrives - no management decision required for season end.
These three give you two immediate-season crops (snap peas mature and finish before summer; cherry tomatoes peak through summer) and one extended season crop (kale spans spring through fall). They cover a range of timing that keeps production moving through multiple growing windows.
Space-Constrained Shortlist
For container gardening or beds under 10 square feet, the per-square-foot figure is the only metric that matters.
Cherry tomato in a 5-gallon container. One plant in a large container on a south-facing patio is the highest-returning use of 2-4 square feet of growing surface. Use a container at least 14 inches in diameter and 16 inches deep. Add a support stake at planting.
Arugula in a window box or small trough. A 12-inch × 24-inch container (2 sq ft) broadcast-seeded with arugula produces a first cut in 30 days and 2-3 regrowth cuts. Resow the same container immediately after the last cut. Outdoor light and a south exposure are adequate. No support structure needed.
Basil in a single 6-inch pot, propagated forward. Buy one basil transplant in spring. Root 8-10 cuttings in water within a week. You now have 9-11 plants from one $3-4 purchase. Pot a few, give some away, harvest from all of them through summer.
Hot pepper as a container perennial. A single hot pepper in a 3-gallon container produces through summer, overwinters indoors, and resumes the following season. Year 1 start cost is $3.50. Year 2 and beyond is zero.
For a tool that helps size expected returns from any bed configuration, the Garden ROI Calculator lets you enter bed area, crop selection, and local price data to compute season return before you plant.
What This Table Doesn’t Capture
The rankings above assume one planting cycle at the frontmatter yield figure. Several crops have economics that look better over multiple seasons:
Garlic can be replanted from your own harvest, reducing Year 2+ start cost to zero. The net return over 5 years from one initial $12 investment in seed garlic, replanting each year, is substantially higher than $20.44 × 5 - it compounds.
Perennial herbs (spearmint, rosemary, thyme, sage) have low first-year returns because the start cost is amortized against only one season. Spearmint yields 2 lb from a $3 potted plant - $33 net in Year 1. In Year 2 and beyond, the plant costs $0 to replace and the net return is the full $36 gross. Over 5 years, one spearmint container returns $36 × 4 + $33 = $177, all from a $3 initial investment. That’s not in the table because the ranking is per-season, not multi-year.
Asparagus doesn’t appear in this table because it produces nothing in Year 1 and light harvest in Year 2 - the formula produces a negative first-year number. By Year 3-20, a mature bed returns $125-300 annually with zero replanting cost. The asparagus ROI analysis covers this case.
The table is a starting-point ranking, not a definitive lifetime calculation. Use it to make planting decisions for this coming season, and adjust as you observe your own yields and local prices.
