Notably, there are white cassava (with green leaves and white petioles) and red cassava (with red petioles). According to the cooking practice of the local people, they only choose the white cassava variety. It is also noted that a Manihot species or cassava variety with narrow purplish leaves (Vietnamese: sắn lá tre) is not used because the high level of toxicity. Also, the bitter cassava (Manihot utilissima, Vietnamese: sắn dù) is also not advised for the same reason.

The general rule is only choose the species or variety/cultivar with a low level of toxicity.
