Hens and Chicks (Echeveria elegans) is an attractive succulent that looks a bit like a tiny agave. It originates from Mexico, thus it loves humidity but not a lot of water (like most succulent species).
Hens and Chicks, like all succulents, need excellent drainage. They also need plenty of sunlight-but not direct sun. These plants can be grown outdoors in cold climates during the summer, but you must bring indoors and place in a sunny window during the winter.
The plant forms tiny rosettes, and will spread slowly by offsets. If you grow in pots, make sure you do not use regular potting soil. Either make your own potting mix, or buy a succulent potting mix to ensure proper drainage. If you purchase potting soil, check to make sure it has little in the way of organic matter such as peat moss; as succulents do not like wet feet.
Water only when the soil is thoroughly dry. A moisture meter works great in cases like this as sometimes it can be hard to tell if the soil is fully dried out.
