Tulsi plant past life was a girl in the previous birth name Vrinda

 

whose name was Vrinda, she was born in the demon clan, she was a devotee of Lord Vishnu since childhood. She used to worship, serve God with great love.  When she grew up, she got married to the demon king Jalandhar in the evil clan.  Jalandhar was born from the ocean. Vrinda was a very pious woman, always used to serve her husband.

Tulsi workship once there was a war between the gods and the demons 

When Jalandhar started going to war, Vrinda said. Lord, you are going to war, as long as you are in war, I will sit in worship and perform rituals for your victory, and till you come back, I will take my pledge

Tulsi won't leave  Jalandhar went to war 

Vrinda took the vow of fast and sat in worship, due to the effect of her fast, even the gods could not win Jalandhar, when all the gods started losing, they went to Vishnu. When everyone prayed to God, then God started saying that Vrinda is my supreme devotee, I cannot deceive her.
