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.
