Cilantro is fairly tolerant of cold weather. Cilantro can handle frost just fine.
The problem with cilantro is that it grows best when you give it lots of water. If you're planning to plant it in the fall, wait until spring before you put it out in the garden. You'll have a better chance of having it grow well then. I've also heard that cilantro does not like to dry out. This is true as well. It won't like to dry out as long as it is kept moist. I don't think there is anything wrong with planting cilantro in the fall, but it's best to wait until spring. It will still grow, but you won't get as much from it. I would plant it early in the spring if you can, because it won't grow as big or as well in the fall.
Cilantro is a member of the mint family, but it's more closely related to parsley. It's often used as an herb and can be found in Mexican, Indian, Asian and Mediterranean cuisines. It's also commonly used in Latin American dishes, including tacos and guacamole. Cilantro is known for its distinct flavor and is often used as an ingredient in cooking. When you add it to dishes, you're adding a bit of spice to foods.
