Difference Between Petunia and Morning Glory

1. Leaf Difference

The leaves of petunia have short petioles or are nearly sessile. The leaves are ovate in shape with an acute apex and a broad cuneate or cuneate base. The leaves are entire, 3 to 8 cm long and 1.5 to 4.5 cm wide.

The leaves of morning glory are broadly ovate or nearly round, with deep or shallow three lobes, about 4 to 15 cm long and about 4.5 to 14 cm wide. The base of the leaves is round or heart-shaped, and the petiole is 2 to 15 cm long.

2. Flower Differences

Petunia flowers grow solitary in the leaf axils, with pedicels 3 to 5 cm long and calyx with 5 deep lobes, which are linear, about 1 to 1.5 cm long and 3.5 mm wide. The petals are blunt at the top and the flowers are white, purple or various reds.

Morning glory flowers are axillary, single or usually two flowers are borne at the top of the inflorescence peduncle. The peduncle varies in length, the corolla is funnel-shaped, and the color is blue-purple or purple-red.
