The difference between round-leaf mint and mint

1. Plant Differences

The stem of round-leaved mint is upright, about 30 to 80 cm high, bluntly quadrangular, and has stripes on the stem.

The stem of mint is upright, about 30 to 60 cm high, and has a sharp quadrangular shape with four grooves.

2. Leaf Difference

The leaves of round-leaved mint are usually sessile, round, ovate or oblong-ovate, 2 to 4.5 cm long, 1.5 to 3 cm wide, obtuse at the apex, heart-shaped at the base, with crenate or crenate-serrated edges, papery leaves, green above, light green below, and covered with soft hairs.

Mint leaves are oblong-lanceolate, lanceolate, oval-lanceolate or elliptical, about 3 to 5 cm long, about 0.8 to 3 cm wide, with a sharp front end, a wedge-shaped or nearly circular base, tooth-like serrations on the leaf edges, and green leaves.

3. Flower Difference

The cymes of round-leaved mint are gathered into cylindrical spikes at the top of the stems and branches. The inflorescence is 2 to 4 cm long and about 6 mm in diameter. The corolla is white, light blue, purple or lavender.

The mint inflorescence is umbel, which is nearly spherical in outline and about 18 mm in diameter. The flowers are usually white.
