The most frustrating herb in Australia. Coriander bolts to seed at the first hint of warmth, making it a cool-season-only crop in most zones. Both the leaves (cilantro) and seeds (coriander spice) are useful. Understanding its biology is the key to managing bolting. This is NOT a herb that grows like parsley. It is a rapid-lifecycle annual that wants to flower and die as fast as possible.

Harvesting Coriander

When ready: Harvest leaves once plants are 10-15cm tall. Harvest before any sign of central flower stem elongation.
