The difference between silk grass and citronella is that silk grass can be woven and citronella can repel insects. Citronella is a perennial herb with slender stems, erect clumps and swollen nodes. Leaf sheaths are mostly broken at the hairless base, and the upper part is shorter than the internodes. The membranous apex is blunt, irregular, with narrow broken leaves and nearly hairless on both sides, all of which are white powder.

I like warm, humid, sunny or semi-cloudy fertile soil with good drainage. I need indoor potted plants in North China. Stems and leaves can be refined into essence with aromatic oil or used in medicine. Cooking fish with leaves can avoid the fishy smell. Many Africans eat fresh leaves.

Compared with other varieties of thatched grass, four-leaf clover has more slender and flexible leaves and reddish stems and leaves. It likes to take root and sprout in the mountains and the rising sun, and often clusters are born between the cracks of stones. It is difficult to pull up four grasses, which is familiar to people who used to cut wood on the mountain. This is a natural straw rope for those who forget to bring it up the mountain and use it locally.
