Not all vegetables are created equal when it comes to garden ROI. A row of potatoes might feel productive, but at $0.80/lb in stores, the savings are modest. A few basil plants, on the other hand, produce harvests worth $100+ from $0.30 in seeds.

This guide ranks the 10 best vegetables to grow for maximum savings — with real numbers on seed cost, yield, store price, and days to harvest.

How We Ranked These Vegetables

Ready to actually get started? See our step-by-step garden setup guide.

We scored each vegetable on four criteria:

1. Price differential: Store price vs cost to grow
2. Yield per plant or per square foot
3. Ease of growing (beginners can succeed)
4. Growing season length (longer = more savings)

#1: Fresh Herbs — Best ROI of Any Garden Plant

Want to grow herbs year-round indoors? Check our indoor gardening guide.

Fresh herbs are the undisputed ROI champion of the vegetable garden. A supermarket bunch of basil costs $2.99–$4.99 and wilts within days. A single basil plant grown from $0.25 in seeds produces fresh leaves all summer.

• Best herbs to grow: Basil, cilantro, parsley, dill, chives, mint
• Seed cost: $0.02–$0.25 per plant
• Store equivalent value per season: $50–$200
• Growing difficulty: Easy (most herbs thrive in pots)
• Days to first harvest: 21–45 days

Pro tip: Grow basil next to your tomatoes — they’re companion plants that repel pests and improve each other’s flavour.

#2: Tomatoes — The Classic High-Value Crop

Tomatoes are the most popular home garden vegetable for good reason. Heirloom and cherry varieties cost $4–$6/lb organic in stores. Homegrown cost: $0.02–$0.05/lb including seeds and soil amendments.

• Seed cost: $0.10–$0.30 per plant
• Yield per plant: 10–20 lbs over the season
• Store price: $2.00–$6.00/lb (higher for organic/heirloom)
• Value per plant: $20–$120
• Growing difficulty: Easy–moderate (needs staking)
• Days to harvest: 60–80 days from transplant

Plant 4–6 tomato plants to supply a family of four through summer and into fall. Preserve surplus as sauce or freeze whole for winter use.

#3: Salad Greens and Lettuce — Fastest Payback

Pre-washed salad mixes cost $4–$6 per small bag — one of the most expensive grocery items per pound. Growing your own cuts this cost by 95%.

• Seed cost: $0.02–$0.05 per plant
• Yield: Multiple harvests per plant (cut-and-come-again)
• Store price: $4–$6 per 5 oz bag ($12–$20/lb)
• Value per 4-foot row: $30–$60 per season
• Growing difficulty: Very easy
• Days to harvest: 30–45 days

Plant successive sowings every 2–3 weeks for continuous harvest. Lettuce bolts in summer heat — choose heat-tolerant varieties for summer planting.

#4: Zucchini and Summer Squash — Highest Yield Per Plant

One zucchini plant can produce 15–25 lbs of squash over the season — often more than a family can eat. The problem isn’t growing enough; it’s finding enough ways to use it all.

• Seed cost: $0.10–$0.20 per plant
• Yield per plant: 15–25 lbs
• Store price: $1.50–$2.50/lb
• Value per plant: $22–$62
• Growing difficulty: Very easy
• Days to harvest: 50–60 days

Grow 2–3 plants maximum — more than that and you’ll be giving zucchini to everyone you know.

#5: Peppers — Best for Warm Climates

Bell peppers cost $1.50–$3.00 each in stores. Specialty and heirloom peppers run $5–$8/lb organic. Each pepper plant produces 10–15 fruits over the season.

• Seed cost: $0.10–$0.30 per plant
• Yield per plant: 5–10 lbs
• Store price: $1.50–$6.00/lb
• Value per plant: $8–$60 (highest for specialty varieties)
• Growing difficulty: Easy–moderate (needs warm soil)
• Days to harvest: 70–90 days

#6: Green Beans — Easy and Prolific

Bush beans are beginner-friendly, require no staking, and produce heavily. Pole beans take up vertical space but produce continuously all season.

• Seed cost: $0.05–$0.10 per seed
• Yield: 2–3 lbs per foot of row
• Store price: $2.00–$3.50/lb fresh
• Value per 10-foot row: $40–$70
• Growing difficulty: Very easy
• Days to harvest: 50–65 days

#7: Cucumbers — High Volume, Easy Growing

Cucumbers are one of the most productive plants for their garden footprint when grown vertically on a trellis. Each plant produces 10–20 cucumbers over the season.

• Seed cost: $0.05–$0.15 per seed
• Yield per plant: 10–20 cucumbers (8–15 lbs)
• Store price: $0.75–$1.50 per cucumber
• Value per plant: $7.50–$30
• Growing difficulty: Easy
• Days to harvest: 50–70 days

#8: Kale and Swiss Chard — Extended Harvest Season

Kale and Swiss chard can be harvested continuously from spring through first frost — and kale actually improves in flavour after a frost. Organic kale costs $3–$5/lb in stores.

• Seed cost: $0.05–$0.10 per plant
• Yield per plant: 5–10 lbs over full season
• Store price: $2.50–$5.00/lb organic
• Value per plant: $12–$50
• Growing difficulty: Very easy
• Days to harvest: 55–70 days (earlier for baby kale)

#9: Peas — Best for Spring

Sugar snap peas from the garden are so good they rarely make it inside. Store prices for fresh peas run $3–$5/lb. Grow them as a spring crop before summer heat arrives.

• Seed cost: $0.05–$0.10 per seed
• Yield per 10-foot row: 4–8 lbs
• Store price: $3–$5/lb
• Value per row: $12–$40
• Growing difficulty: Easy (needs trellis)
• Days to harvest: 60–70 days

#10: Winter Squash and Pumpkins — Best for Storage

Butternut squash, acorn squash, and pumpkins store for 3–6 months in a cool, dry place — meaning summer garden work feeds you through winter. Butternut squash costs $1.50–$2.50/lb in stores.

• Seed cost: $0.10–$0.25 per seed
• Yield per plant: 3–6 squash (8–20 lbs)
• Store price: $1.50–$2.50/lb
• Value per plant: $12–$50
• Growing difficulty: Easy (needs space)
• Days to harvest: 80–110 days
