Botanical Description and Taxonomy of the Cassava Tapioca Plant
Botanically, cassava is a perennial shrub that produces fleshy, tuberous roots rich in starch and belongs in the Euphorbiaceae family with other plants such as Castor oil plant (Ricinus communis), Poinsettia (Euphorbia pulcherrima), Croton (Codiaeum variegatum), Leafy spurge (Euphorbia esula), Chinese tallow tree (Triadica sebifera) etc.
Physical Description of Cassava Tapioca Plant
The yuca plant can be described by obvious three parts: the stem, leaves, and roots. Let’s take a closer look:
Stem
The stem of the cassava tapioca plant is woody and cylindrical, reaching up to 10 feet (3 meters) in height with an average diameter of 10 cm.
It is light brown or grayish, with bumpy nodes running along its length. These nodes serve as growth points where new shoots emerge during sprouting.
The stem is fibrous and hardy, allowing it to withstand drought conditions. The branches grow in an opposite pattern, forming a bushy appearance.
Cassava stems are not only used for propagation but also as fuelwood or, in some cases, animal feed after processing. For a detailed guide on cassava stems, read cassava stems: varieties and propagation
Leaves
Cassava leaves are palmate (hand-shaped) with 3 to 9 lobes, spreading outward like fingers.
They are deep green, though some varieties have reddish or purplish hues on the petioles.
The petioles (leaf stems) can grow up to 30 cm long, attaching the leaves to the main stem.
These leaves play a crucial role in photosynthesis, supplying energy for root development.
Nutritionally, cassava leaves are high in protein, vitamins A and C, and iron, making them a valuable food source in some regions, especially when cooked to neutralize toxins.
For a detailed information on the cassava leaves, read our in-depth article here.
Roots/Tubers
The cassava tubers are elongated, cylindrical, and slightly tapered at the ends. They grow underground in clusters, with each plant producing 4 to 10 tubers, depending on the variety and growing conditions.
The outer layer, or rind, is thin, detachable, and varies in color, typically brown, reddish, or white.
The inner flesh is firm, white, or yellow, and loaded with starch, making it a key carbohydrate source.
Cassava roots contain small amounts of calcium, phosphorus, and vitamin C, though they require proper processing to remove natural toxins before consumption.
For a comprehensive guide on cassava tuber, including parts and anatomy, read our post on cassava tuber.
The cassava plant is susceptible to many cassava pests and diseases including cassava mosaic disease, cassava brown streak disease and more. Using biological and chemical methods can get rid of pests and diseases.
