During the growing season, they put out fibrous roots to take up moisture and nutrients. Typically grow in a cluster, with the swollen tuberous portions radiating out from a central point. The growth buds are on the stem or at the stem base rather than on the roots themselves like in rhizomes, corms or tubers. In plant producing annual, deciduous shoots new growth buds, or eyes form at the base of the stem where it meets the tuberous root. This area is called the crown.  Tuberous roots are true root tissue, unlike tubers, rhizomes, and corms which are stem tissue, and bulbs which are leaf tissue. A tuberose root is not a taproot or caudex. Tuberous root system allows the plant to survive catastrophes which may kill the above ground parts.
