Is it permissible to plant and eat a lettuce called “iceberg lettuce trinity” because of its name?
Question

I am a farmer who plants lettuce, I have recently found out that a lettuce variety which is very common in my land carries the title "iceberg lettuce trinity".
Praise be to Allah.Lettuce is a kind of plant that it is permissible to eat. Allah has blessed us with good food that He has created and brought forth for us from the earth. Allah says (interpretation of the meaning): 
“O mankind! Eat of that which is lawful and good on the earth, and follow not the footsteps of Shaytaan (Satan). Verily, he is to you an open enemy” [al-Baqarah 2:168] 
“O you who believe (in the Oneness of Allah — Islamic Monotheism)! Eat of the lawful things that We have provided you  with, and be grateful to Allah, if it is indeed He Whom you worship” [al-Baqarah 2:172]
The permissibility with regard to these things that we are permitted to grow and eat has nothing to do with the names that people give to them, because the names come from these people, each according to his environment and language. 
Based on that, the fact that this is called “iceberg lettuce trinity” does not make it haraam to grow it or eat it, even though in our research we did not find out who gave this name to it. Whatever the case, even if the word trinity in the name is a religious name connected to deviant Christianity, it does not affect the fact that it is permissible.
