'Caribe' is a superior variety of cilanatro that tolerates heat well and is slow to bolt. This is a great plant if you use a lot of cilantro in salsas and cooking. We always plant young cilantro plants AND seed at the same time. When the plants go to seed, let the seed drop. Meanwhile, the second crop will be growing leaves. You can also keep sowing seed every two weeks until late summer. Eventually, you will have a self-sown cilantro patch. Did you know that when cilantro goes to seed, the dry seed is ground to make the spice coriander?
