What is the difference between creeping grass and purslane?

1. Different varieties

The creeping grass is also called dog-tooth grass, melon seed grass, stone nail, dog-tooth petals, etc. It is a plant of the Crassulaceae family and the Sedum genus. It is distributed in most parts of my country and is also distributed in North Korea and Japan.

Portulaca oleracea is an annual succulent herb belonging to the Portulacaceae family and the genus Portulaca. It is native to South Asia and is now distributed in both the northern and southern regions of my country and is relatively common.

2. Different stems

The stems of creeping grasses are mostly creeping and relatively low. If grown in a pot, they will grow down along the edge of the pot.

Some of the stems of Portulaca oleracea lie flat, while others grow at an angle and occupy a larger area.

3. Different leaves

The leaves of the creeping grass are whorled, oblanceolate to oblong, about 1.5-2.5 cm long, and have a relatively pointed tip.

The leaves of Portulaca oleracea are opposite, and the single leaf is obovate-wedge-shaped, relatively thick and flat, like the shape of horse teeth, about 1-3 cm long and 0.6-1.5 cm wide. The top of the leaf is somewhat rounded and sometimes slightly concave. The surface of the leaf is dark green and the bottom is light green.
