The difference between long-leaf thorny sunflower and soft-leaf thorny sunflower

1. Tree shape difference

The long-leaved thorny palm tree can reach a height of 15 meters, with a thick, cylindrical trunk.

The stems of the soft-leaved amaranth grow in clusters, about 1 to 3 meters high, with a stem diameter of about 10 centimeters and a persistent triangular petiole base.

2. Leaf Difference

The petiole of the long-leafed sunflower is short, thick at the base, and yellow-brown in color. The pinnate leaves are 5 to 6 meters long and are bow-shaped.

The leaves of the soft-leaved sunflower are 1 to 1.5 meters long, with linear pinnae. The pinnae are soft, 20 to 30 centimeters long, dark green on both sides, and arranged in two rows.

3. Flower Difference

The long-leafed thorny sunflower has a spike-like inflorescence, small, yellowish-brown flowers, three petals, spherical female flowers, and a cup-shaped calyx.

The soft-leaved echinops has an inflorescence that can be up to 20 cm long. The flowers have three petals, which are needle-shaped, about 9 mm long, and gradually pointed at the apex.
