What is the difference between sulphureus and caltrops?

1. Leaf Difference

The leaves of the sulphur aster are opposite, bipinnately compound leaves with deep lobes. The lobes are lanceolate with short tips. The edges of the leaves are relatively rough and the leaves are wide.

The leaves of California poppy are basal, about 10 to 30 cm long, with long petioles. The leaves are gray-green and mostly have pinnate-shaped fissures. The shapes of the lobes vary, including linear-acute, oblong-acute, or blunt-oblong-spoon-oblong.

2. Flower Differences

The flowers of Sulfur Daisy are large and brightly colored. The ligulate flowers are pure yellow, golden yellow or orange-yellow, and the tubular flowers in the center of the disk stand out clearly in the disk and are yellow or reddish brown.

The flowers of the California poppy are solitary at the top of the stems and branches. The pedicels are 5 to 15 cm long. When the flowers bloom, they are cup-shaped with wavy edges. The flowers are usually yellow.
