Culantro is a herb typically grown in tropical areas as a replacement for cilantro. Cilantro is one of our favorite herbs to use in cooking, but our growing season here in Oklahoma makes it difficult to grow because of how hot it gets. Culantro is a great alternative to cilantro that flourishes in heat and can handle as much sun as you give it. It has a bit more of a kick than traditional cilantro, but we are usually using it in Mexican dishes so we enjoy this extra kick! Culantro does not typically transplant well so it is best to do them from seed.
