Generally we keep leaves of Tulsi over Prasāda( SACRAMENT) we offer to Gods. But recently in Ganesh Festival our priest while doing pooja told us that "Tulsi is not offered to Lord ganesha, it is offered to Lord Vishnu" on this I asked reason, then priest answered that it was a curse to Tulsi and since then Tulsi plant is kept out of our house(Aangan) and there is a more story behind that which he don't know.

Do any One know story what happened between Lord Ganesha and Tulsi?
