Arugula and leaf lettuce when just the leaves are pinched, produce over a long season. Both if planted in the cool spring tend to bolt quickly, but plant some later after the weather starts to warm, and those plants will give a much longer harvest. The lettuce will produce at least a month longer into the heat. Late spring planted Arugula will last many months and sometimes all the way through the winter here in zone 8 South Carolina.
With succession planting, I'm able to harvest cucumbers, squash, and zucchini from late spring until frost in the fall. Without succession planting, the plants generally give out by early to mid summer, because of pests, disease, heat, or just plain get worn out.
In some areas cucumbers and tomatoes grow great all season long, but in the hot south, it takes a little creativity to get a continuous crop from early summer until frost. I have to keep a continuous supply of young replacement tomato plants growing throughout the spring and summer. They serve as replacements any time the older plants die, usually because of summer blight or other heat related disease. Young vigorously growing plants are usually not affected, and will grow through the stressed period to pick up production when that of older plants comes to an end.
Okra produces from early summer until late fall.
Succession planting with bush green beans will give an almost continuous crop from spring through late fall.
Garlic stores very well, so while the harvest period is short, the crop lasts for at least 6-9 months.
