The Lotus tree is another interesting magical plant featured in literature for muggles. Found throughout the southern parts of Europe, the many stories about this tree (or bush) also serve a warning. Lotus trees bear large round fruits, which are white on the outside and light green on the inside. Eating these fruits causes one to feel very full… however Herbologists would suggest leaving the food alone at all costs. Potioneers may use leaves, or the fruit of the tree, to produce feelings of contentment as well as forgetfulness in their brews. Yellow to green flowers bloom on Lotus trees in the spring, with its fruits in season all year long.

The Lotus tree is quite vividly expressed on Homer's Odyssey, giving muggles a clear expression of the faults of the tree. On an island, the only food available to eat was from the tree of the Lotus fruit. After one has eaten from the tree, they forget about their friends and family and homes, thus causing the travelers to lose their desires to find a way home, and encouraging them to take up a life of idleness. The consumer of the plant is also overtaken by feelings of drowsiness.

The Lotus tree is also referenced in the biblical Book of Job, where God is describing how a behemoth (a rare magical creature) lives surrounded by Lotus trees. This passage may be found in Job 40:21–22.
