Plant broad beans, also called fava beans, directly in the garden 4 to 7 weeks before the last frost in spring. Sow broad beans as soon as the soil can be worked for harvest before the weather warms. Broad beans are a cool-season crop that grows best in temperatures ranging from 60° to 65°F (15-18°C)
Mustard is a cool-season crop. Mustard matures in 30 to 50 days so time the planting for harvest when the average temperature is around 60° to 65°F (16°-18°C). Mustard bolts easily so it is often grown for autumn harvest, but it can be grown as a spring crop where spring weather tends to stay cool.
Collards are a hardy cool-weather crop. It can be grown in early spring and in mid to late autumn. Sow collards seeds in the garden 3 to 4 weeks before the last frost. Start transplants 6 to 8 weeks before setting out in the garden. Transplants can be set in the garden 4 weeks before

Radishes grow best in the cooler time of the year. Most are hardy to spring and autumn chills; a few varieties can withstand the summer heat. Sow seeds for small early varieties 4 to 6 weeks before the last frost. Plant midseason or summer varieties in mid to late spring. Late varieties—called winter radishes—should be
Endive and escarole are cool-season crops. They can be grown in early spring and in fall. Sow endive and escarole seeds directly in the garden 2 to 4 weeks before the last frost in spring. To set out transplants start seeds indoors 4 to 5 weeks before transplanting. Set transplants in the garden 4 weeks
Parsley is a biennial usually grown as an annual. The leaves are used for flavoring, garnishing, and in salads. Sow parsley seeds directly in the garden 2 to 4 weeks before the average last frost date in spring.

All parts of Florence fennel can be eaten. The bulb can be prepared like celery; it can be eaten raw or cooked. The leaves and tenderest branches can be used in soups and salads. The seeds can be used as a flavoring in baked goods. Florence fennel requires a long, cool growing season, about 100
Lettuce can be grown in any home garden and in containers. It is a cool-weather crop and usually does not grow well in the heat of summer. Planting lettuce in the wrong season is the cause of most failures. In warm-winter regions grow lettuce in late fall, winter, and spring. In cold winter regions, grow
