You can't see the difference between the pictures, because these two things look very similar to those planted in my family, and they are very close, easy to cross, and have a bad taste. Mint should be easy to tell. If you pick a leaf and crush it in your hand, you will smell a strong mint flavor, that is, chewing gum and mints that you often eat. That smell is authentic mint. The taste is weak. It may be planted in a string. The taste of fish is completely different from that of mint. I can't describe it … but then you can tell mint. The mint flavor is obvious, and you can tell the mint flavor at once. Maybe fish vanilla is a variety of mint, but the two flavors are completely different.
