|discussion=<p><i>Manihot grahamii</i> is native to northern Argentina, southeastern Brazil, Paraguay, and Uruguay, and is sometimes cultivated for its distinctive, attractive foliage. The flowers are relatively inconspicuous, but are much-visited by bees. This is the most cold-tolerant <i>Manihot</i> species; above-ground stems survive light frosts and if severe cold kills the aerial shoot system outright, new stems can regenerate from underground parts. It survives well and self-sows in garden settings as far north as tidewater Virginia; northern limits for the persistence of plants escaping from cultivation have yet to be established. In addition to characteristics noted in the key, herbarium specimens frequently exhibit contracted petiole bases.</p>
