Tarragon
Artemisia dracunculusFrench tarragon brings an anise-like sharpness that is hard to substitute, but it is grown from divisions or cuttings, never true seed. It dies back in cold weather and returns from the roots each spring. The one rule: give it sharp drainage, since wet winter soil is its main enemy.

When to sow tarragon
- Sow from around your last expected frost until about 6 weeks after your last expected frost.
Plant divisions, not seed — French tarragon rarely sets viable seed.Set young plants at the same depth they sat in their pot.Water in well and keep soil evenly moist while roots take hold.
Divide every few years — this keeps clumps vigorous and productive.Cut back stems after flowering to encourage a fresh flush of leaves.Mulch over winter in cold spots to protect dormant roots from frost.
Pick young shoots — flavor is best on tender new growth, not old stems.Harvest through the growing season; regular picking encourages branching.Freeze or steep sprigs in vinegar to preserve flavor past the season.
