What Is the Difference Between Eupatorium and Spider Plant? A Quick Guide to Telling Them Apart
1. Leaf differences
Eupatorium leaves are long-elliptic, oblanceolate, or long-elliptic-lanceolate, about 5 to 10 cm long and 1.5 to 2.5 cm wide, with lateral lobes, and the leaf tip gradually tapers to a point. Both surfaces of the leaf are smooth and hairless, and the leaf edges have irregular fine teeth or coarse teeth.
Spider plant leaves are basal, linear, sword-shaped, or linear-lanceolate, very narrow and long, 10 to 30 cm long and 1 to 2 cm wide, slightly narrowed toward both ends.
2. Flower differences
Eupatorium bears head-like inflorescences, mostly growing at the top of the stem and the tips of branches and arranged in compound corymbs; the inflorescence is about 3 to 6 cm, and the flowers are white or slightly reddish.
Spider plant flowers are white, usually in clusters of 2 to 4, arranged in racemes or panicles.
