What is the difference between cosmos and cineraria?
Plant form differences: Cosmos stems have no hairs or only a few soft hairs, while cineraria stems have dense white long soft hairs. Leaf differences: Cosmos leaves are bipinnately lobed, with linear or filiform-linear lobes. Cineraria leaves are relatively broad and wide, broadly heart-shaped. Flower differences: Cosmos pedicels are longer than those of cineraria.
I. Plant form differences
Cosmos grows 1-2 m tall, and its stems have no hairs or only a few soft hairs. Cineraria grows 30-70 cm tall, with upright stems covered in dense white long soft hairs.
II. Leaf differences
Cosmos leaves are bipinnately lobed, and its lobes are linear or filiform-linear. Cineraria leaves are relatively broad and large, 10-15 cm long and 10-20 cm wide, broadly heart-shaped.
III. Flower differences
Cosmos inflorescences are capitula, with solitary flowers, pedicels 6-18 cm, and flower diameter about 3-6 cm. Its ray florets are white, pink, or purplish red, and its disc florets are yellow. Cineraria inflorescences are also capitula, but its pedicels are only 3-6 cm long. Its flower colors are similar to those of cosmos, but the ray florets also include light blue, which the former lacks.
