Tulsi Pooja, or Tulsi Vivah,

Tulsi Pooja, or Tulsi Vivah, is a traditional Hindu ritual that involves the ceremonial marriage of the Tulsi plant (holy basil) to Lord Vishnu, usually represented by a Shaligram stone or an idol of Krishna. This ritual is particularly popular among Hindu households and is observed during the month of Kartika (October-November), often marking the end of Diwali festivities.
