During the summer a great variety of flowers flourish throughout the sierra, some of which are used as food or natural medicine by the local inhabitants, who are known as the Tarahumara.
Suvel katab kogu mäeahelikku tohutu mitmekesine lillevaip. Kohalikud tarahumara indiaanlased kasutavad mõningaid sealsetest taimedest toiduks või siis loodusraviks.
