All annual and biennial herbs are grown from seed. Of the perennials, though, many are easier to propagate by methods other than seed; for example, rosemary, sage, tarragon and lavender from cuttings or mint and sweet woodruff from runners. Other perennials are worth growing from seed as they are easy to germinate. This group includes catnip, chamomile (flowering), chives, fennel (green and bronze), feverfew good King Henry, hyssop, loaves, marjoram (French), oregano, rue, sage (common), salad burnet, sorrel, sweet cicely, thyme (common), Welsh onion, winter savory, and wormwood. Indeed, growing from seed may be the only way to obtain many of the wild flower herbs and unusually herbs from abroad.
