The biggest basil I have ever seen – Reddit Post

This is in the South of Greece. The plant is over 2m/7ft high and the trunk is easily 10cm/4″ in diameter. Bigger than most grown men’s forearms. I’ve seen people grow big basil plants on Reddit, but then it’s a dozen plants in one pot, and they’re only one season old. This here is just one tree.

Can anyone identify the kind of basil? Is it a perennial variation? This can’t be regular Genovese, right? Also, how old do you think this plant is? 5 years? 10 years? 20 years?
