The pronunciation of the two is the same. As for why the spelling is so different, it is actually because this plant was written as garlic moss at first, but on the one hand, it was mistakenly written as garlic moss. On the other hand, people later thought that garlic moss was simpler and simpler, so they continued to use this typo.
On the Origin of Garlic Moss
Garlic moss does not grow from garlic seedlings. Garlic moss and garlic seedlings belong to the same relationship. They all grow from garlic. Garlic moss is a flower stem that grows in garlic, while garlic seedlings are buds that grow in garlic seedling stage. They are not the same thing.
But they all grow on garlic, and the names of garlic moss in different regions are different. Garlic moss is also called garlic sprout in the south.
