Growing herbs in Zone 8

The herbs below grow well in Zone 8. Use the zone's frost dates — last frost Late February – late March, first frost Mid November – mid December — to time sowing and transplanting right.
Herbs are among the highest-value crops by square foot and among the easiest to grow. Most culinary herbs prefer well-drained soil and at least partial sun. Annual herbs like basil are direct-sown each season; perennial herbs like rosemary and thyme return year after year in mild zones.
