What Vegetables Grow in Partial Shade? Matching Crops to 2, 4 and 6 Hours of Sun
Plenty of gardens have a sunny strip and a lot of somewhere else: the side of the house, the bed under a maple, the corner the fence shades after lunch. The good news is that not every vegetable needs full sun. The useful rule is to look at what you eat. Fruits and seeds (tomatoes, peppers, squash, beans, corn) need the most light. Roots need less. Leaves need the least. This guide matches crops to hours of direct sun using the Sunlight Requirements Guide, and is honest about what shade costs you.
Start with a measured number, not a guess. If you have not counted the hours yet, how to measure hours of direct sun in your garden walks through a one-day sun log.
The four bands, and what the guide suggests
Enter your daily hours of direct sun and the guide returns one of four categories, each with a short list of suitable plants:
| Hours of direct sun | Category | Plants the guide lists |
|---|---|---|
| 6 or more | Full Sun | Tomato, pepper, squash, cucumber, bean, corn, sunflower, lavender, rosemary, marigold |
| 4 up to 6 | Partial Sun | Lettuce, carrot, beet, pea, broccoli, cabbage, spinach, parsley |
| 2 up to 4 | Partial Shade | Kale, chard, arugula, mint, cilantro, radish, leaf lettuce, hosta |
| Under 2 | Full Shade | Hosta, fern, astilbe, coleus, begonia, impatiens, lily of the valley |
So a bed with 1.5 hours reads Full Shade, 2 or 3 hours read Partial Shade, 4 or 5 hours read Partial Sun, and 6 hours reads Full Sun. Notice that the full-shade list contains no vegetables at all. Below about two hours of direct sun, food crops are a struggle, and that bed is better used for ornamentals, a seating area or a compost bin.
About 6 hours or more: fruiting crops
Tomatoes, peppers, eggplant, squash, cucumbers, melons, beans and corn need full sun to flower and set fruit well. In less light they grow tall and thin, flower sparingly and produce small or few fruits that ripen late. If you have only one sunny bed, give it to these. A cherry tomato will produce something with five hours; a large beefsteak or a pepper in the same spot is likely to disappoint.
Sun-loving herbs belong here too: rosemary, lavender, thyme and oregano come from dry, bright places. Basil also wants as much sun as you can give it.
About 4 to 6 hours: roots, brassicas and peas
This is the most useful band in a part-shaded yard. Root crops such as carrots and beets, cabbage-family crops such as broccoli and cabbage, peas and lettuce all grow here. Expect two trade-offs:
- Slower growth. Roots size up more slowly and may finish smaller. Allow extra days beyond the seed packet's figure.
- Smaller heads. Broccoli and cabbage form heads, but often smaller ones than in full sun.
The guide's description for this band reads “4–6 hours; morning sun is kinder in hot weather”, and that matters for the crops on its list. In hot summers, cool-season crops such as lettuce, spinach and peas usually do better when their four to six hours come in the morning, with shade in the hottest part of the afternoon. In a cool, cloudy climate the reverse can be true. If you know which part of the day your sun arrives, use that as a tiebreaker.
About 2 to 4 hours: leafy greens
Leafy crops are the backbone of a shade garden. Kale, chard, arugula, leaf lettuce, spinach and mustard greens all produce in two to four hours of direct sun, especially with bright indirect light the rest of the day. Leaves will be thinner and growth slower than in a sunny bed, but you harvest the leaves anyway, so there is nothing to wait on.
Shade even has an upside here. In midsummer, lettuce and arugula in a hot sunny bed turn bitter and bolt to seed; the same crops in partial shade often keep producing longer. Herbs that like moisture, such as mint, cilantro, parsley and chives, also cope well.
Radish appears on the guide's partial-shade list. It will grow there, but because you eat the root, expect smaller roots and more leaf than in a sunnier bed. Pick-and-come-again leaf lettuce is a more reliable choice for the darkest spots in this band.
Getting more from a shaded bed
- Bounce the light. A light-colored fence or wall behind the bed reflects extra light onto plants.
- Raise the bed. A taller raised bed can lift small plants above the shadow line of a low fence; see how much soil to fill a raised bed for what that costs in soil.
- Prune, where it is yours to prune. Thinning a few low branches can add an hour of light. Large trees and anything near power lines are a job for a qualified arborist.
- Plant shade crops in the shadow of tall ones. In a sunny bed, the north side of a row of tomatoes or pole beans gives lettuce afternoon relief in summer.
- Space for the light you have. Plants in lower light benefit from a little more room so leaves do not shade each other. The Plant Spacing Calculator shows how counts change with spacing.
- Water by the bed, not the yard. Shaded beds dry more slowly than sunny ones. Check the soil with a finger before watering rather than running every bed on the same schedule.
Plants to be careful with
Two plants that do well in shade deserve a warning. Lily of the valley, on the guide's full-shade list, is poisonous to people, cats and dogs if eaten, and hostas can make pets ill if they chew them. Rhubarb, often grown in a part-shaded corner, has toxic leaves; only the stalks are eaten. If children or pets use the garden, place these thoughtfully, teach children not to graze on plants, and never eat anything you have not positively identified.
What the guide does not cover
- It does not measure light. It sorts the hours you type into a category.
- It does not weigh time of day or intensity. Four hours in the morning and four in the afternoon read the same.
- Its lists are short and general. They name common choices for each band, not every crop or variety. Variety matters: some lettuces and peas are sold as more heat or shade tolerant than others.
- It does not predict yield. A crop that "grows" in partial shade will usually yield less than in full sun.
- Seasonal change. One number stands for the whole season, but shadows shift and trees leaf out.
A quick plan for a part-shade yard
- Log the hours of direct sun for each bed.
- Give the 6-hour beds to tomatoes, peppers, squash and beans.
- Put roots, peas and brassicas in the 4 to 6 hour beds.
- Fill 2 to 4 hour beds with leafy greens and moisture-loving herbs.
- Use under-2-hour spots for ornamentals, paths or storage.
