The difference between Aster and Aster calyx

1. Difference of blades

The basal leaves of Aster are oblong or elliptical-spoon-shaped, gradually narrowing into long petioles in the lower half, with a total length of 20-50 cm including the petiole. The lower leaves are spoon-shaped and oblong, while the middle leaves are oblong or oblong-lanceolate. All leaves are thick papery.

The leaves of the purple calyx are ovate to ovate, and rarely extend downward at the base to become cuneate. The petiole is about 6-30 cm long.

2. The difference between flowers

Most asters have capitulate inflorescences with long peduncles and linear bracts. The bracts have 3 layers and are linear or linear-lanceolate. There are about 20 ligulate flowers, and the tongues are blue-purple.

The purple-calyx scape is about 60-100 cm high and has 10-30 flowers. The bracts are oblong-lanceolate and white. When in bloom, the tepals expand upward in a nearly funnel-shaped shape and are purple-red in color.
