About cilantro
Cilantro is a fast cool-season herb that bolts quickly in heat, so it’s best grown in spring and fall and sown in succession. The leaves are cilantro; let the same plant flower and set seed and you get coriander. It’s easy from seed but resents transplanting, so sow it where it will grow.

Why does my cilantro bolt so fast?＋

Is cilantro the same as coriander?＋
Same plant — cilantro is the leaf, coriander is the dried seed. Let a plant flower and it produces coriander.
